 GENERAL FEATURES

Presentation of the unit

This series of air-water chillers and heat pumps satisfies the cooling and heating requirements of residential plants of medium size.
All the units are suitable for outdoor installation and can be applied to fan coil plants, radiant floor plants and high efficiency radiators
plants.
The refrigerant circuit, contained in a compartment protected from the air flow to simplify the maintenance operations, is equipped
with scroll compressors mounted on damper supports, brazed plate heat exchanger, thermostatic expansion valve (standard for IR)
or electronic expansion valve (standard for IP / option for IR), reverse cycle valve, dehydrator filter, axial fans with safety protection
grilles, finned coil made of copper pipes and aluminium louvered fins with subcooling section. The circuit is protected by a safety gas
valve, high and low pressure switches and differential pressure switch on the plate heat exchanger. The plate heat exchanger and all
the hydraulic pipes are thermally insulated in order to avoid condensate generation and to reduce thermal losses.
All the units can be equipped with variable speed fans control that allows the units to operate with low outdoor temperatures in cooling
and high outdoor temperature in heating and permits to reduce noise emissions in such operating conditions.
The low noise acoustic setting up (AS) is obtained, starting from the base setting up (AB), reducing the rotational speed of the fans
and mounting sound jackets on the compressors and the technical compartment is clad with soundproofing material of suitable thick-
ness.
The eXtra low noise acoustic setting up (AX) is obtained, starting from the low noise setting up (AS), further reducing the rotational
speed of the fans and using finned coil with bigger surface.
All the units are supplied with a management and control electrical panel containing general switch, phase presence and correct
sequence controller, microprocessor controller with display and all the other electrical components with IP54 minimum protection
degree.
All the units are accurately built and individually tested in the factory. Only electric and hydraulic connections are required for instal-
lation.

Produces cold water in the same way as the standard version plus hot water from 30 to 70°C at the same time. This is achieved
by installing a water-refrigerant gas heat exchanger between the compressor and coils in order to recover 25 to 30% of the heating
capacity that would otherwise be dispersed in the air. It helps to remind that hot water production is possible only in combination with
cold-hot water production in the main heat exchanger and it is subordinated by it.
VR: Total Heat Recovery version
Produces cold water as in the standard version plus hot water at a temperature of 30 to 55°C at the same time. This is achieved
thanks to a water-refrigerant gas heat exchanger that totally recovers the heating capacity that would otherwise be dispersed in the
air. The total heat recovery function is enabled and disabled by means of a valve on the compressor delivery of each circuit: when
the temperature of the water that enters the recuperator drops, the valve switches the hot gas flow from the condensing coils to the
recovery heat exchanger. On the other hand, when the temperature of the water reaches the set-point, the valve shuts off the heat
recuperator and switches the hot gas flow to the condensing coils. It helps to remind that hot water production is possible only in
combination with cold water production in the main heat exchanger and it is subordinated by it.

Tw= Outlet water temperature °C kWa = Compressor power input (kW)

kWf = Cooling capacity (kW) kWt = Heating capacity (kW)
The standard performances refer to a 5°C temperature difference between the water entering and leaving the heat exchanger and to operation of the unit with all fans at
nominal or maximum speed. A 0.44 x 10-4 m2 K/W fouling factor has also been considered with the unit installed at zero meters above sea level (Pb = 1013mbar).
The performances are declared no considering any correction due to water flow rate and water side pressure drop (gross performance).

(1) : at these temperatures the fans are at maximum speed.

(2) : ATC (Advanced Temperature Control) function may occur, if present.

Tw= Outlet water temperature °C kWa = Compressor power input (kW)
kWf = Cooling capacity (kW) kWt = Heating capacity (kW)
The standard performances refer to a 5°C temperature difference between the water entering and leaving the heat exchanger and to operation of the unit with all fans at
nominal or maximum speed. A 0.44 x 10 m K/W fouling factor has also been considered with the unit installed at zero meters above sea level (Pb = 1013mbar).
-4 2

The performances are declared no considering any correction due to water flow rate and water side pressure drop (gross performance).
(1) : at these temperatures the fans are at maximum speed.

kWtr = Recovery heat capacity TWR = Desuperheater outlet waterl temperature, ∆tin-out= 5°C
The standard performances refer to a 5°C temperature difference between the water entering and leaving the heat exchanger and to operation of the unit with all fans at nominal
or maximum speed. A 0.44 x 10-4 m2 K/W fouling factor has also been considered with the unit installed at zero meters above sea level (Pb = 1013mbar).
The performances are declared no considering any correction due to water flow rate and water side pressure drop (gross performance).

 NOISE LEVELS

Open field
The noise levels refer to units operating in the nominal conditions (A35W7), due to a change of Q=2
external air temperature noise levels may change to ensure proper functioning of the unit within
operating range.
The acoustic pressure levels are calculated 1/ 5 / 10 meters away from the outer surface of the unit
operating in the free field and resting on a reflecting surface (directional factor of 2).

SWL = Sound power levels, with reference to 1x10-12 W.

The Total sound power level in dB(A) measured in compliance with ISO 9614 standards, is certified
according to the Eurovent certification program.
Eurovent certification (E) exclusively refers to the Total Sound Power in db(A), which is therefore the
only binding acoustic specification (the values of the Octave bands in the table are indicative).
SPL = Sound pressure levels, with reference to 2x10-5 Pa.
The sound pressure levels are values calculated by applying the ISO-3744 relation (Eurovent 8/1).

 OPERATING RANGE

Operating range

The table below lists the operating ranges within which correct operation of the units is guaranteed, depending on the Version and
Operating Mode available for each type of unit.
Remember that in Heat Pump units, heat recovery only takes place during operation in the cooling mode.

NOTE: the admissible limits for water flow rate on heat exchangers are indicated under the related pressure drop graph (see
section "water pressure drop"). If the unit is equipped with pumping module the admissible limits are indicated under the
related working head graph (see section "working head").

 DIMENSIONAL AND PHYSICAL DATA

Minimum space required for operation

To correctly install the unit, comply with the measurements for the
free area that must be left around the unit, as shown in the figure.
This will ensure good air circulation, allow the unit to operate cor-
rectly and facilitate future maintenance work.
The distances must be doubled if the unit is to be installed in a pit.

NOTE. Allow for an uncluttered area of not less than 2.5 me-
ters above the unit.

Mod. 40÷115 130÷200 UM

E 1600 2000 mm

Position of condensate drain

The condensate tray (if present) must have a suitable drain trap to prevent spilling of water during operation.

Vibration-damper installation

To prevent the operating unit from tran-

smitting vibrations to the bearing struc-
ture, vibration dampening materials
should be inserted under the bearing
points.
The unit can be supplied with the rub-
ber or spring vibration dampening ac-
cessory. This must be mounted by the
installer.

 RECEPTION AND POSITIONING

Positioning

Before positioning please consider the overall dimensions and the technical requirements of the system and the unit, electric and
hydraulic connections and any air pipes/ducts or free passages.
Neglecting these aspects may decrease performance and operational life of the unit and therefore increase the operating costs and
maintenance.

Units are designed to be installed OUTSIDE and in fixed positions.

The unit is designed to be installed outside and in a fixed location and accessible only by qualified and authorized personnel.
Safety valve (if present): the installer is required to evaluate (according to EN378-2) the need and type of pipe to piped outlet in
accordance with local regulations.
To prevent the transmission of vibrations evaluate the need for vibration dampers mounting

Before placing the unit be sure that:

• the location is in a safe accessible place

• the framework or the floor is adequate to support the weight of the unit WORKING (tank filled with water, etc…), please refer
to weight paragraph
• support points are leveled and aligned
• the place can not be subject to flooding
• the maximum level of the snow does not obstruct the airflow to the unit

To ensure the best air circulation to the unit and thus ensure a smooth operation it is recommended to:

• avoid obstructions to air flow near or above the unit

• protect the unit from high winds that can favor or not the airflow
• protect the unit from heat sources or pollutants (chimneys, extractors…)
• protect the unit from air stratification or recirculation (avoid ducting of the fans, containment structure, high walls or corners
next to the unit)

These advises if not respected can lead to a lower efficiency of the unit or to high pressure stops (in summer) or low pressure stops
(in winter).

 HYDRAULIC CONNECTIONS

General rules

A mesh filter (hole Ø<1mm for plates heat exchanger Ø<1.5mm for shell and tubes heat exchanger) must be installed on the unit’s
water inlet otherwise warranty is immediately forfeited. The filter
The filter performs the function of blocking any foreign matter in the system’s plumbing circuit (shavings, machining debris, etc.)
limiting or avoiding possible problems of fouling (that decreases the heat exchange coefficient), erosion, and clogging
The clogging and fouling of the exchanger can lead to a reduction of the water flow rate and. In the case that the exchanger works
as evaporator- of the evaporation temperature: these 2 factors can cause the icing of the exchanger
The icing event leads to the bursting of the exchanger, the inlet of water into the refrigerant circuit and so the necessity of a re-
placement of the main components (compressors, filters, expansion valves,. Etc.) and an accurate washing of components as
refrigerant pipes, coils, etc., practically the rebuilding nearly complete of the refrigerant circuit.

The filter must be maintained clean: this is so necessary verify the cleanness after the unit installation and checking periodically
the state.

Protection devices

Standard supply includes a differential pressure switch situated between the water inlet and outlet of the heat exchanger to avoid
freezing if the water flow stops for any reason.
Activation is calibrated for a 80 mbar ±5 Δp, while resetting occurs with a Δp of 105 mbar ±5.
The differential pressure switch opens the contact and shuts down the compressors when the water flow ratey decreases and Δp ≤
80 mbar ±5.
The differential pressure switch closes and therefore the unit can restart when the water flow rate increases and Δp ≥ 105 mbar ±5.
• Standard supply includes an antifreeze heater placed between the external thermal insulation and the shell of the exchanger and
controlled by the main electronic controller of the unit in order to protect the evaporator full of water (but not the pipes) from the winter
icing when the unit is in stand-by mode. The exchanger is protected down to an outdoor air temperature of -20°C.
NOTE the antifreeze protection only worlk if the unit is electrically connected the standby period.
It is recommended to install a water paddle flow switch at the water inlet of the unit (it can be supplied as accessory or option): the
water paddle flow switch has to be electrically wired in series with the differential pressure switch.
It is mandatory to calibrate the trip out of the water paddle flow switch at a water flow rate value higher than the minimum water flow
rate admissible for the exchanger (re. section Pressure Drop).

Tips for a successful installation

For a correct design and installation of the hydraulic plant comply the local laws governing safety matters and sound…
The following information is suggestion for a correct installation of the unit:
• Before connecting the unit to the system wash adequately the pipes using clean water, filling and emptying and cleaning the filters.
Only after that proceed connecting the unit to the system; this operation is crucial to ensure proper start-up without the need to have
repeated stops to clean the filter, with the possible risk of damage to heat exchangers and other components.
• Check by qualified personnel the quality of the water or of the mixture used; avoid the presence of inorganic salts, biological load
(seaweeds, etc.) suspended solids, dissolved oxygen and the pH. Water with inadequate characteristics can cause a pressure drop
increase due to a rapid fouling of the filter, energy efficiency decrease and corrosive symptom increase that can damage the unit.
• The pipes must have the least possible number of bends to minimize load losses and must be adequately supported in order to
prevent the connections of the unit from being excessively stressed.
• Install on-off valves near components that need to be serviced to isolate them when maintenance work needs to be done and to
allow them to be replaced without having to discharge the system.
• Before isolating the pipes and charging the system, carry out preliminary inspections to make sure that there are no leaks.
• Isolate all the chilled water pipes to prevent condensation from forming along the pipes themselves. Make sure that the material
used is the steam barrier type, failing this, cover the insulation with an appropriate protection. Also make sure that the air venting
valves can be accessed through the insulation.
• Do not forget to install or at least allow for the installation of pressure and temperature reading instruments on the inlet and outlet
parts of the hydraulic circuit. These instruments will allow you to monitor the operation of the system.
• The circuit can be kept under pressure by means of an expansion tank and a pressure reducer. A plant filling unit can also be used in
order to automatically charge the system and keep it at the desired pressure if it drops below a certain pressure value. Install manual
or automatic values in the highest point of the system to eliminate air from the circuit.
Fit manual or automatic valves at the highest point in the circuit in order to vent air from the circuit.
• the water connections are Victaulic-type joints for hooking up to the unit.
The joints allow the pipes to expand due to changes in temperature and in addition the elastomer gasket and the specified play help
insulate and absorb noise and vibration.
• If vibrations dampers are installed under the unit, it is recommended to use flexible couplings before and after the water circulation
pump and near the unit.
• Install on the outlet of the unit a suitable valve able to regulate the water flow.
• Avoid that the weight of the connection pipes pushes on the hydraulic connections of the unit using approved supports.

Check that plant components are suitable to bear the maximum static pressure (it depends on the height of the building).

Precautions for the Winter

The water could freeze and damage the exchanger of the unit and other parts of the system during the winter period, if the system
was to remain at a standstill. This problem can be obviated in 3 different ways:
1. Drain the system completely, taking care to drain the plate exchanger (in order to drain the unit’s piping system completely, open
the water drain ball valves and the air vent valves, open any valves closed).
2. Operate with glycol water taking account, depending on the % of glycol, of the factor of correction of the refrigerating capacity,
power input, water flow rate and losses of head (see table on following page)
3. If it is certain that the unit will always be powered throughout the winter, the unit is able to protect itself from freezing, down to a
temperature of -20°C: this is possible thanks to an antifreeze electric heating element installed on the plate exchanger and intelli-
gent control of the water pump that must be governed by the microprocessor board (see the “Electric Connections” section).
If the unit is fitted with a Storage tank, solution no. 3 requires installing the tank antifreeze heating element accessor.

Air vent and water drain

On the plumbing circuit feeding the unit, especially when equipped with the standard pipe kit, the installer must fit an appropriate
number of valves (manual or automatic) at the top of the circuit in order to vent any air in the plumbing system. In the same way, he
must install a water drain valve in order, when necessary, to drain the unit's plate exchanger completely (especially during the winter
in order to prevent freezing that would seriously jeopardize the operation of the unit). For units with the complete pipe kit there is an
air vent valve on the top pipe (water inlet) and a water drain valve on the bottom pipe (water outlet). See “Accessories and options”
section.

Valve regulating diagram valve

To prevent problems from occurring when the unit is started with very cold water, you are strongly advised to install a mixer valve as
shown in the diagram.
The valve must be regulated to suit the temperature at which the water flows into the desuperheater (see diagram): the graph on
the right shows the type of adjustment to use.

Water connections must be performed carefully as for the evaporator (filter, circuit washing, etc.)
Perform all necessary interventions to avoid RISK OF FREEZING (tubes insulation, emptying of circuit, addition of glycol, anti-
freeze resistances).
Water temperature can reach high temperatures (up to 100°C for VD unit, up to 65°C for VR unit), therefore:
• avoid RISK OF BURNS by adopting the necessary precautions (insulations of tubes, temperature detecting station on water if the
sanitary use is foreseen, etc.).
• install safety valves and specifically dimensioned expansion tanks in the hydraulic circuit.

1) Pipe groove inspections

Check the depth and diameter of the grooves and their distance from the pipe ends. Make sure that the T
work has been carried out with care and that the end surface of the pipes is smooth and not ovalized.
Make sure that there are no notches, burrs or other imperfections that could impair the tightness.
Groove dimensions in mm A=16-B=8-C=57.2-D=1.6

2) Checking the seal and relative lubrication

Make sure that the type of seal used is compatible with the nature and temperature of the fluid. Signal
green EPDM seals are used.
Apply a film of grease to the seal: on the back, on the side flanks and on the inner lips that contact the
pipe. Work in conditions of the utmost cleanliness as particles of dirt could damage the seal. Always
and only use synthetic grease. Greasing makes it easier to fit the seal on the pipe and improves the
tightness. It also allows the seal to slide within the connection, avoiding tensions and projections near
the bolts.

3) How to fit the seal

Fully insert the seal into the end of a pipe. Make sure that the seal lips adhere to the pipe itself.

4) Alignment
Align the pipes and move their ends near to each other. Now push the seal, centering it on the two pipe
ends. The seal must remain inside the grooves.

5) Joint assembly
Remove one bolt and loosen (without removing) the other one. Seat part of the body of the joint at the
bottom, between the pipe ends, inserting and edges of the grooves. Now seat the other part of the
body at the top, on the two ends, and close the joint. Make sure that the parts of the body of the joint
touch each other.

6) Nut torquing
Fit the previously removed bolt back in place and tighten both nuts by hand. Now torque them with the
relative wrench, tightening them alternately a few turns.
WARNING:
If one nut is fully tightened at a time, the seal could slip between the jaws of the opposite side of the
joint.

 MAXIMUM VOLUME OF WATER

Maximum volume of water in the system with wet module

Before filling the water system, it is advisable to consider the type of installation in question, i.e. check the difference in level between
the wet module and user. The following table gives the maximum water content of the water supply system in liters, depending on
the capacity of the standard expansion vessel supplied and the pressure at which it should be charged. The expansion vessel setting
must be regulated to suit the maximum positive difference in level of the user.
Maximum setting value 600 kPa.
With a positive H of more than 12.25 meters, calculate the expansion vessel precharge value in kPa using the formula below:

Expansion vessel precharge= [H/10.2+0.3] x100 = [kPa]

 ELECTRICAL CONNECTIONS

1) Connection to the electricity main

• Power supply line;
The unit’s power supply line must be laid by following a clearly defined route in order to make it as correct as possible any without
any breaks. Pass the line through the opening on the button of the electrical panel. Secure the line integral with the structure of the
unit. Then continue inside the panel and connect the conductors directly to the input terminals of the main disconnecting device of the
unit. The characteristics of the main lines should be determined by qualified personnel specialized in the design of electrical systems,
according to your national regulations and standards.
• Power supply system;
The power cables of the unit’s supply line must be taken from a system of symmetrical three-phase voltages (difference between
voltage max 2%) and of a separate protection conductor.
V= 380÷415V
f= 50 Hz
• Protection on supply side:
An automatic switch must be installed on the supply side of the side in order to protect against any overcurrents and indirect contacts
that could occur when the unit is operating.
It is advisable to install an automatic current limiter switch in order to limit the effective short-circuit current in the connecting point of
the unit. This allows a protection device with a lower breaking capacity than that required in the connection point to be sized like the
main circuit-breaker of the unit.
The line and switch must be coordinated in compliance with the current laws governing electrical safety matters, regarding the type
of installation and environmental conditions in which the unit must operate.
• Protection conductor (ground wire):
The protection conductor from the feeder line must be connected straight to the ground screw identified by code “PE”, which ensures
the equipotential connection of all metal grounding points and structural parts of the unit.
• Signals and data lines
Do not exceed the maximum allowed distance of the cable as shown in the wiring diagram. Put cables away from power lines with
a different voltage or emitting electromagnetic noise, if really necessary do not to put in parallel but only cross with these cables to
90°. Do not put cables near equipment that can create electromagnetic interference (antennas, speakers, radio repeaters etc ...). Any
shielding of the cable must be connected to a ground without noise, while preserving the continuity across the total length of the cable.
• Connection
Always refer to the wiring diagram supplied with the unit. Verify that the network has characteristics corresponding to the data shown
on the nameplate of the unit. Before starting work, verify that the switching device at the start of the line power unit is open, locked
and a warning sign shown. Make the connection to the ground first that the others phase; protect the wires using cable properly fitted.
Before powering on the unit, ensure that you have restored all the protections that were removed during work on connection.

2) Electric panel
• Protection degree:
The electric panel casing is made from sheet metal and has IP54 protection rating at the doors directly accessible from the outside.
The other parts of the casing guarantee a protection degree that is at least equivalent to IP22, as established by the current laws in
force: this has been achieved since the panel has further protection against the penetration of solid foreign bodies and atmospheric
agents thanks to the unit structure in which it is housed.
• Starting and stopping function:
The red handle on the panel door directly acts on the main circuit-breaker. The handle also acts as a door lock since it ensures that
the unit is only powered when the door is shut. The stopping function carried out by the main circuit-breaker is classified as type “0”
since the unit is stopped by immediately cutting off the power supply.

3) Reference standards
• The provisions established by the following Directives have been complied with to ensure the safety of the electrical products placed
on the European Union market:
- Low Voltage Directive 2006/95 EEC which also includes the following harmonized standards:
CEI EN 60335-1 and 60335-2-40.
Classification:CEI EN 60204-1. Safety of unitry. Electrical equipment of units. Part 1: General rules.
- Directive 2004/108/EEC concerning “Electromagnetic compatibility”.

4) User connection
Inside the electrical panel is available a user terminal where you can have:
a) pumps start-up and safety devices
b) two user configurable inputs
c) digital Input for water paddle flow switch
d) integrative resistance output relay
e) clean contact for general alarm
f) external signal from the compressors running

Moreover, VR units contains the following terminals:

g) pumps start-up and safety devices
h) digital input for remote enable
i) digital Input for water paddle flow switch

For more details refer to the wiring diagram of the unit.

 ALARMS

Alarm activation and reset

The controller can perform a complete diagnosis of the unit, detecting all operation faults and signalling a number of alarms.
Activation of an alarm involves :
• blocking of users concerned
• signalling of alarm code on the display (in case of simultaneous alarms the one with the lowest index is displayed whereas the
complete list of active alarms can be shown by accessing the “Status \ AL”) menu
• recording of event in the alarms history

Alarms that can damage the unit or system require manual resetting or an action by the operator to reset the controller (pressing
the UP and DOWN buttons at the same time). It is advisable to carefully check the cause of the alarm and make sure the problem is
eliminated before restarting the unit. In any case the unit restarts only if the cause of the alarm has ended.

Less critical alarms are automatic reset. As soon as the cause is eliminated the unit starts working again and the alarm code disap-
pears from the display. Some of these alarms become manual reset if the number events per hour exceeds a fixed limit.

Press any button to deactivate the alarm : alarm signalling disappears from the display, the alarm LED starts flashing and the Alarm
digital output is disabled. This operation does not affect the alarm in progress.

Number of events per hour

The counting of events per hour is provided for some alarms : if the number of events reaches a fixed limit in the last hour, the alarm
goes from automatic to manual reset.
Sampling of alarms occurs every 112 seconds. If an alarm is activated several times in a sampling period (112 seconds) it is counted
only once.

Example. If an number of events per hour equal to 3 is set, it must have a duration of between 2*112 seconds and 3*112 seconds so
that the alarm goes from automatic to manual reset.

Alarms history
The controller enables the recording of alarms occurring during unit operation (up to a max. of 99 events). The following are memo-
rised for each event :
• alarm code
• input time
• input date
• output time
• output date
• type of alarm (automatic or manual reset)
This information can be shown by accessing the “Programming \ EU” menu.
When the number of events memorised is more than 99, alarm Er90 is generated and the subsequent events are memorised over-
writing the oldest alarms.
The alarms history can be cancelled by means of the Evr function available inside the “Programming \ FnC” menu.

Er05 Low pressure – Sequence meter - Fans thermal protection - EEV driver alarm
The alarm becomes manual reset when the number of events per hour is more than parameter al12.
The alarm is bypassed for parameter al11 seconds from activation of the compressor or the reverse cycle valve.

Er10 Compressor 1 thermal protection

The manual-reset alarm intervenes in the event of activation of the compressor thermal protection or the thermostat located on the
outlet of the compressor .

ER11 Compressor 2 thermal protection

The manual-reset alarm intervenes in the event of activation of the compressor thermal protection or the thermostat located on the
outlet of the compressor .

ER10 ER11 * Compressor 1 thermal protection - Compressor 2 thermal protection - High pressure switch (PAA)
The manual-reset alarm intervenes in the event of activation of the compressor 2 thermal protection or the thermostat located on the
outlet of the compressor 2 AND in the event of activation of the compressor 1 thermal protection or the thermostat located on the
outlet of the compressor 1 and/or more likely it means the auto-reset high pressure switch (PAA) trips in.

Er20 / Er25 Differential pressure switch - flow switch plant / recovery

The alarm is activated if the associated digital input remains activated for at least 5 seconds and automatically resets if the digital
input remains not activated for at least 3 seconds. The alarm becomes manual reset if the digital input remains activated for more
than 10 seconds. The alarm is bypassed for 15 seconds from pump activation.

ER 21 ER22 / ER26 Pump thermal protections plant / recovery

When thermal protection trip in the controller stop the pump and the unit; if the controller manages two pumps it involves the activation
of the other, if both thermal protection trip in the controller stops the unit.

Unit with 1 pump:

The alarm s active if the input is active for at least the time AL15 (plant) / AL18 (source). It remains automatic for the time
AL16 (plant) / AL19 (source): if, during this time the alarm is deactivated the unit can restart to work, instead if remains active becomes
manual.

Unit with 2 pumps:

The alarm s active if the input is active for at least the time AL15 (plant) / AL18 (source). It remains automatic for the time
AL16 (plant) / AL19 (source): during this time the controller stops the working pump and switch on the other one, if the alarm is
deactivated the unit can restart to work, instead if remains active becomes manual.

If there is the flow switch alarm during the first startup of the unit control the cleaness of the water plant.
Particularly diring the startup a lot of impurities due to the pipes installation can be present into the hydraulic plant
and if the plant was not carefully washed, despite the installation of water filters
with adequate mesh size impurities as sand,
chips or similar could enter into the exchangers choking them and, in worst cases,
lead to a serious damage or broke for freezing (if the excahanger is working as evaporator).
Er30 / ER31 Antifreeze plant / recovery
The alarm switch off the compressors, activates the heaters and the pumps (if off).
It is a very dangerous alarm: check carefully the possible cause and eliminates it before reset the alarm.

ER45 Clock failure

If the clock is not working it is not possible to set time bands and the record of date and hour for the alarms present in the alarm
events.

ER46 Alarm: clock to be set

There is this alarm if the controller is not electrically supplied for several days.

ER47 LAN communication error between electronic controller (base, remote, expansion)
There is this alarm if there si not communication between the devices connected trough LAN.

ER60 ER61 ER63 ER64 Failure of temperature probes (plant and recovery)
This alarm stops the unit. It could be caused for short-circuit, breakage or out of range of the probe

Er62 Failure of liquid temperature probe

If the alarm is active the fans work only on-off on request (on when compressor is on). It could be caused for short-circuit, breakage
or out of range of the probe. In and out defrosting are managed by the timing of compressor.

Er68 Failure of external air temperature probe

If the alarm is active all controls based on this probe (i.e. dynamic setpoint or defrost) are disabled: the unit can continue to work. It
could be caused for short-circuit, breakage or out of range of the probe.

Er80 Configuration fault

Appears when the parameters are not set correctly.

Er90 Maximum number of recordings in alarms history exceeded

Indicates that the alarms history buffer is full. Every new alarm will be memorised, cancelling the oldest alarm.

* Note: The manual-reset high pressure (PAM) does not have reference on the control display so you can not identify it
through the internal diagnostics as it acts directly on contactors, it may happen that the control display does not signal
any error but the compressors are however still, in this case switch-off the unit then rearm the manual-reset high pressure
switch by pressing the button located at the top of the switch.

Recording hours of operation

The controller can record the hours of compressors and pumps operation. Access the “Status \ Hr” menu to show the values.

Power failure
In case of a power failure, when the power is restored the controller will go to the status prior to the power failure. The procedure is
cancelled if a defrost is in progress. All timing in progress is cancelled and reinitialised.

Clock
The controller has an internal clock for memorising the date and time of each alarm occurring during unit operation (see “Alarms
history”). The clock can be set by accordingly to "Date and time set up".

History alarms
The controller is able to log and save up to 90 alarm events. Alarms are visible in the menu “Par \ eu”.
Push SET to display alarm EU00 (if present) that is always the latest, EU01 is the one before and so on.
Scroll to UP and DOWN keys to display all the other alarms, push SET to display more information about the event chosen: alarm
code (see alarm table), start event time, start event date, stop event time, stop event date,type of alarm (automatic or manual reset).
Example of an alarm visualization:

Timer scheduling

The scheduling allows to set weekly time zones to obtain a reduce in energy consumption when the cooling or heating demand is
lower.

There are 3 time zones each one with 4 events per hour.

For each event, you can set hours and minutes of start and stop, an operating mode (Stand-by or ON), a cooling set point and a
heating set point.

ATTENTION: you can not change the operating mode via scheduling. The operating mode (cooling or heating) will be the
same adopted before the enabling of time scheduling.
To enable time scheduling you must set up the date and time into the controller

 PROBE CHARACTERISTICS

NTC10K-25°C type temperature probes are used.

When the probe bulb is at a temperature of 25°C the electrical resistance measurable at the probe ends with a multimeter is approx.
10 kW. The thermistor of these probes has a negative temperature coefficient: the electrical resistance value decreases as the tem-
perature increases.

To find out if a temperature probe is faulty or disconnected, check the correspondence between the resistance value in kW and the
bulb temperature in °C according to the following table.

Temperature [°C] Resistance [kΩ] Temperature [°C] Resistance [kΩ] Temperature [°C] Resistance [kΩ]

For a reliable check it is not necessary to control each single value, but just several sample values. If the instrument gives an infinite
resistance, this means the probe is disconnected.

 NETWORK COMUNICATION

The unit can communicate on serial line using the Modbus communication protocol with RTU coding.
The unit can be connected to an RS485 network by means of the serial interface supplied as an accessory, and respond to requests
from any master device connected to the network.

Serial line settings

The serial line must be set as follows :
• baud rate : 9600
• data bits : 8
• stop bits : 1
• parity : even
All the devices connected to the same serial line MUST use the same settings.

Device address
To communicate correctly, each device connected to the serial network must have an univocal address (“Modbus individual address”)
of between 1 and 247. This address can be set by modifying the parameter CF63.

Modbus commands
The Modbus commands implemented by the controller are :
• parameter reading 3 (Hex 03 : Read Holding Registers)
• parameter writing 16 (Hex 10 : Write Multiple Registers)

Table of addresses
All the available resources are stored in the controller as WORD (2 byte) and therefore require the reading or writing of an entire
Modbus register. According to the Modbus protocol, to identify a register of address X the address X-1 must appear in the message.
Some registers contain more than one piece of information : in this case the bits representing the resource value are identified by
means of the number of bits used (“Bit number”) and by the least significant bit (“Lsb”). In the writing operation for these registers it
is necessary to read the current register value, modify the bits representing the resource concerned and rewrite the entire register.

Example.
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Bit number = 4
Lsb = 7 0 1 1 0 1 0 0 1 1 1 0 1 1 0 1 0
Resource value = 3

The resources can be read only (R), write only (W) or read and write (RW).

To interpret the value written in the register it is necessary to consider the value of CPL, EXP and UM :

CPL : if the register represents a number with sign (CPL = Y) carry out the following conversion :

0 = register value < 32767 : resource value = register value

32768 = register value < 65535 : resource value = register value – 65536

EXP : indicates the exponent of the power of 10 to be multiplied by the register value to obtain the resource value.

EXP Multiplier
-2 10-2 0,01
-1 10-1 0,1
0 100 1
1 101 10
2 102 100

MU : indicates the unit of measure of the resource

IMPORTANT. DO NOT modify any parameter not indicated in the tables provided or indicated as a read only parameter (R), other-
wise the warranty will be cancelled.

 START-UP

General Rules

To validate the contractual warranty, the unit must be set at work by technicians from an authorized assistance center. Before they
are called, check to make sure that all parts of the installation have been completed, the unit levelled, the wet connections made
with the relative air vent and the electrical connections made.

MAINTENANCE
General Rules

Maintenance is of extreme importance if the plant is to operate in a regular way and give fade-free service. Have extraordinary mainte-
nance work done by qualified and authorized personnel, according to EU Regulation 303/2008 of 2 April 2008 (and later) that requires
companies and technicians that perform maintenance / repair, leakage checking and recovery / recycling gases must be certified as
required by local regulations. Comply with the safety precautions given in the relative section of this manual and take all the necessary
precautions. The following information is only a guide for the end user.
Maintenance keeps unit efficiency, reduce the speed of deterioration over time and collect information and data to understand the
efficiency of the unit and prevent failures. We suggest to prepare a booklet of installation according European legislation.

Routine maintenance

The inspections described below, to which the unit must be subjected, do not require specific technical know-how.
They merely include a few simple inspections involving certain parts of the unit.
Call an authorized assistance center if actual maintenance work is required.
The table below gives a recommended list of inspections which should be carried out at the indicated intervals.
Provide controls and interventions more frequently in case of heavy (continuous or intermittent high, close to operating limits, etc ...)
or critical (essential service such as data centres, hospital etc ...) use.

DESCRIPTION WEEKLY MONTHLY EVERY SIX MONTHS

Visual inspection of the unit •
Inspection of hydraulic circuit •
Inspection of electrical system •
Inspection of condensing system •
Inspection and adjustment of operat. parameters •

• Structure of the unit

When checking the condition of the parts that form the structure of the unit, pay particular attention to the parts liable to rust.
If traces of rust are noted, they must be treated with rust-inhibitor paint in order to eliminate or reduce the problem.
Check to make sure that the external panels and the fans of the unit are well fixed.
Bad fixing gives rise to noise and abnormal vibrations.

• Hydraulic circuit
Check visually to make sure that there are no leaks in the hydraulic circuit. If the pumping module accessory is installed, it is advisable
to make sure that the water filter is clean.

• Electrical system
Make sure that the power cable that connects the unit to the distribution panel is not torn, cracked or damaged in a way that could
impair its insulation.

 MAINTENANCE

• Inspection of the condensing system

WARNING: The finned pack exchanger has fins made of aluminium or some other thin material, thus even accidental contact could
cause cuts. Comply with the instructions in the relative section.
• Condensing coils
In view of the function of this component, it is very important for the surface of the exchanger to be as free as possible from clogging
caused by items that could reduce the fan’s air flow rate and, thus, the performances of the unit itself.
The following operations may be required:
- Remove all impurities (such as paper scraps, leaves, etc.) that could be clogging the surface of the bank either by hand or using a
brush (comply with the above mentioned safety prescriptions).
- If the dirt has deposited on the fins and is difficult to remove by hand, use a flow of compressed air or pressurized water on the
aluminium surface of the coils, remembering to direct the flow in a vertical and opposite to the standard flow direction to prevent the
fins from being damaged.
- “Comb” the coils with the relative tool, using the appropriate comb spacing for the fins if some parts of them are bent or squashed.
• Helical electric fans
Visually inspect these parts to make sure that the electric fans are well fixed to the bearing grille and that this latter is fixed to the
structure of the unit. Check the fan bearings, causing abnormal noise and vibration, and close the terminal box and cable glands.

• Water heat exchanger

The exchanger must ensure the maximum heat transfer possible so keep it clean and free from dirt that may reduce efficiency; make
sure that the temperature difference between water outlet temperature and evaporation does not increase over time, if the difference
exceeds 8 -10 ° C is necessary to proceed cleaning the water side of the exchanger, keeping in mind the following: water circulation
must be in the opposite direction than normal, the fluid velocity does not exceed 1.5 times the nominal velocity and use just water or
moderately acid products but only water for final washing.

• Water filter
Make sure to clean the filter and remove any impurities that block the proper flow of water, contributing to increase pressure drop and
therefore energy consumption of the pumps.

• Water pumps (if present)

Check leakage, the state of the bearings (any anomalies are highlighted by noise and vibration), the closing of the terminal box and
integrity of the cable.

• Reading and adjustment of the operating parameters

This control can be done using the pressure gauges (if installed) of the refrigerant circuits and using the pressure and temperature
gauges (if installed) of the hydraulic circuits of the unit (evaporator + heat recovery - if present)

Provide a unit book that allows you to track of the actions taken on the unit, so it will be easier to cadence adequately the
various interventions and will facilitate a possible troubleshooting.
Please take note of: date, type of action, description of action, measurements performed, anomalies identified, alarms re-
gistered in the alarm history, etc. ...
