Product and Documentation Changes

SKOV A/S reserves the right to change this document and the product herein described without further notice.
In case of doubt, please contact SKOV A/S.
The date of change appears from the front and back pages.
IMPORTANT
Notes concerning alarm systems
Breakdowns, malfunctions or faulty settings may cause substantial damage and financial losses when regulat-
ing and controlling the climate in a livestock house. It is therefore essential to install a separate, independent
alarm system that monitors the house climate concurrently with the climate and production controller. According
to EU-directive No. 98/58/EU, an alarm system must be installed in all mechanically ventilated houses.
We would like to draw your attention to the fact that the product liability clause of general terms and conditions
of sale and delivery specifies that an alarm system must be installed.

In case of an operating error or inappropriate use, ventilation systems can result in production
losses or cause loss of lives among livestock.
We recommend that ventilation systems should be mounted, operated and serviced only by
trained staff and that a separate emergency opening unit and an alarm system be installed as well
as maintained and tested at regular intervals, according to terms and conditions of sale and deliv-
ery.
Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-
fied personnel in compliance with the applicable national and international standard EN 60204-1
and any other EU standards that are applicable in Europe.
The installation of a power supply isolator is required for each motor and power supply to facilitate
voltage-free work on the electrical equipment. The power supply isolator is not included.

1 Guidelines
This user manual deals with the daily operation of the house controller. The manual provides the fundamental
knowledge about the functions of the controller that is required to ensure optimum use of it.

Some functions are optional and only used in specific set-ups of the house controller. These func-
tions are shown with an optional icon.

If a function is not used, e.g. 24-hour clock, it is not shown in the user menus of the controller. The manual may
therefore contain sections that are not relevant to the specific setup of your controller. See also the Technical
Manual or, if necessary, contact service or your dealer.
This manual's Operating Instructions consists of a general introduction, which describes briefly how to operate
the house controller.
This is followed by descriptions of the controller functions.

10" and 7" controller display

The displays shown in this manual are from a 10" controller display where the menu overview is shown to the
left in the display. If you use a controller with a 7” display, the menus are shown in the middle of the display.
Using a 7” display you can press the menu headlines at the top
of the display to go back step-by-step in the menus.
If more steps are available that what can be shown, you can
press the 3 dots and select a menu from the appearing list.

3.3 TrustMe
TrustMe information is meant to give a better understanding of how the controller is working.
For selected control areas the following is described:
• the current status.
• the reason for the current adjustment.
• what the next step in adjustment will be.
The information is available from pages with cards with the icon
in the right corner.
Press the card to see how the controller is currently working.

Press the icon in the left corner to close the window again.
The TrustMe information can also be added as a card to a
page. See also Creating pages [} 18].

3.4 Activity log

The controller registers operation, events and alarms with the information of when they took place and when
they were deactivated. It often happens that several alarms follow each other because one defective function
also affects other functions.
For instance, a flap alarm can be followed by a temperature alarm as the controller cannot adjust the tempera-
ture correctly with a defective flap. Thus, the previous alarms give you the possibility of following an alarm
course back in time to detect the error that caused the alarms.
The activity log contains information about alarms such as:
• When the alarm occurred.
• When the alarm ended.
• The value that triggered the alarm.

Other active alarms are marked on the list.

• Hard alarms are marked in red.
• Soft alarms are marked in yellow.
• Deactivated alarms are gray.
The icon for Activity log indicates the number of active alarms, as long as an alarm situation has not ended.

With correct setup of the house controller, the daily user of the house should only exceptionally need to make
manual changes to the settings.

The controller can continuously adapt the climate to the ani-

mals' age and needs on the basis of the strategy laid out.
In addition, it can via its adaptive functions adapt the regulation
to the very current conditions such as e.g. changing outside
temperature.

SKOV A/S recommend the use of adaptive control.

The controller has adaptive control of the following climate functions:
• Heating
• Humidity
• Ventilation
• Tunnel cooling

See also Technical manual for further description of adaptive control.

User Manual 25

4.2 Temperature
The controller adjusts the inside temperature according to the Temperature setpoint.
When the inside temperature is too high, the controller increases the ventilation level to supply more fresh air.
When the temperature is too low, the controller reduces the ventilation level to keep the heat in the house; the
heating level is increased if needed.

4.3 Humidity
This section is relevant only to houses with a humidity sensor.

The air humidity in the house is important both for the indoor climate and for the well-being of the animals. In re-
lation to air humidity the regulation must ensure a suitable level - neither too high nor too low.
When the animals are young, it is especially important to avoid a very high humidity level (> 80%) in order to
limit pathogens in the environment. A very low humidity level (<40%) can dry out the house, but also the ani-
mals.
In relation to animal welfare, it is generally more important to keep the correct inside temperature than to keep
the humidity within a precise level. Therefore, the house controller regulates for humidity only when the temper-
ature control allows it.

 DOL 534 • DOL 539

Note that a combination of a high inside temperature and high air humidity (>85%) can be life-threatening
to the animals.

Ventilation
- air change

Heating

Cooling

Humidity is supplied to the housing air partly from the animals, feed, drinking water and litter, and partly from the
cooling and humidification functions.
Basically, the humidity of the house can be regulated by either increasing or decreasing the ventilation level or
by increasing or decreasing the heat supply. The house controller has several humidity control principles, which
you can choose from depending on what suits the house in question. See section Humidity control mode
[} 29].
The most important humidity values can be seen and adjusted on the page types Daily view, Climate and House
view. See also section Daily view and House view.

Adaptive control
From the factory the control is set to adaptive control. This means that the house controller constantly adapts
the regulation to the current conditions. Thus, there is less need for the user to make manual changes to set-
tings.

The following sections describe the functions and setting options available in the humidity menu.

4.3.1 Humidification
Humidification increases the air humidity of the house by supplying atomized water to the air. It is important to
maintain a certain air humidity, among other things to prevent dehydration of the animals’ mucous membranes.
The house controller increases humidification as long as the air humidity is below the humidification setpoint.
During batch production, the house controller can automatically regulate the humidification in relation to the age
of the animals by adjusting the batch curve. See also the section Batch curves.

4.3.2 Humidity control mode

The air humidity can be regulated based on the correlation between the air temperature and its ability to contain
moisture. The warmer the air is, the more water vapor it can contain.
It is generally estimated that for every 1 °C temperature change, the humidity will change 5%.
• As the temperature rises, the relative humidity decreases.
• As the temperature falls, the relative humidity increases.

If the temperature falls so much that the relative air humidity reaches 100%, the water vapor will start to con-
dense (dew point).
These general principles can be exploited by choosing the humidity control mode that best suits the require-
ments of the animals and the individual house (geographical location).

The house controller has 3 primary humidity control modes, each of which takes its own area into account.

When the house controller has been set to control humidity according to the humidity heat principle, it will re-
duce a too high humidity level by gradually increasing the ventilation. The increased air change will make the in-
side temperature fall. To maintain the temperature of heating temperature, the heating system will gradually
supply more heating.

degree of humidity ventilation at the start of a batch when the animals are small.

4.3.2.2 Temperature reduction

The house controller can control the house humidity according to the humidity control principle with temperature
reduction when the animals can tolerate a temperature drop at high air humidity. This function limits the use of
heating in the house but cannot keep the air humidity at the humidity setpoint.
In your daily work, you should only adjust humidity via Humidity setpoint.
Consequences Method of Operation
Less heat consumption The inside temperature that is controlled as it is reduced so
that ventilation can be increased.
Possible to regulate humidity without heat
Does not maintain the set humidity
The animals must be able to tolerate the temper-
ature drop at high humidity.

Temperature reduction with heat supply

When the house controller is set to control humidity according to the temperature reduction principle, the con-
troller will adjust a too high humidity level by reducing the inside temperature by a few degrees (reduction).
At a lower temperature setting, the house controller will thus increase ventilation and consequently the change
of air. When this has made the inside temperature drop, ventilation will decrease to minimum ventilation in order
to limit the heat loss from the ventilation.
If this is insufficient to maintain the reduced House heater setpoint, the controller will gradually supply more
heat.

Temperature reduction without heat supply

30 User Manual

When the house controller has been set to control humidity according to the humidity heat principle, it will re-
duce a too high humidity level by gradually increasing the heat supply. The increased heat supply will make the
inside temperature rise. In order to maintain the temperature, the ventilation system will gradually increase ven-
tilation.

4.3.3 Intelligent humidity control - at high outside temperature and outside

humidity
As an alternative to the standard setup of the controller, the humidity control can be changed so that a high air
humidity in the livestock house is reduced by raising the inside temperature. The intelligent humidity control reg-
ulates both inside and outside temperature, as well as inside and outside humidity, and thus optimizes the hu-
midity control according to current climatic conditions.
It is intended for areas with a high outside temperature and a high outside humidity, whereas humidity, at high
humidity via increased ventilation, is less suitable.
This feature is only available when an outside and inside humidity sensor is installed.

The intelligent humidity control takes over when the following conditions are met:
1. High inside humidity (higher than Humidity setpoint)
2. High outside humidity (exceeds the limit for Outside humidity)
3. High outside temperature (higher than the Temperature setpoint of 6°C)

Example values for when Intelligent humidity control takes over

Current conditions Requirements
Inside humidity 85% 1. High inside humidity 85% > 75%

4.4 CO2
This section is relevant only to houses with a CO2 sensor.

Using a CO2 sensor, you can monitor the current CO2 level in the livestock house and use it as an indicator of
the air quality.
The feature either increases or lowers the minimum ventilation and the current ventilation level, depending on
the atmospheric CO2 content. i.e., if it was higher or lower than the set CO2.

Before day 10, the CO2 ventilation can be limited to 0%.

After Day 10, the CO2 ventilation cannot be less than 25% of the minimum ventilation.
If the inside temperature drops below the heating temperature setpoint, the climate controller reduces the CO2
ventilation by up to 25%.

The following sections describe the functions and setting options available in the CO2 menu.

It is possible to search for functions via the search function in the Settings menu. See section

Lack of ventilation in the case of CO2 alarm

In the case of CO2 sensor errors or high CO2 alarm, the controller deactivates the CO2 function
and enables Minimum ventilation. It is to avoid a defective CO2 sensor causing a too low or too
high ventilation level.
It is therefore essential that Minimum ventilation and Number of animals are correctly set, even

4.5 NH3
This section is relevant only to houses with a NH3 sensor.

By using a NH3 sensor, the current NH3 level (ammonia) in the house can be monitored and used as an indica-
tor of the air quality.
This function increases the ventilation and the current ventilation level depending on the air’s NH3 content, that
is if it is higher than the NH3 setpoint. Ventilation due to NH3 can, however, not exceed 25% of the ventilation.

Note the setting of the NH3 setpoint.
As long as the NH3 level is above the setpoint, the controller will increase the ventilation to reduce the

A too low setting can result in very high heat consumption or a temperature drop in the livestock house if
there is no heat supply available.

If the inside temperature drops below the heating setpoint, the climate controller will gradually reduce the NH3
ventilation.

These functions are only accessible in houses with heat recovery units. The availability of the
functions described depends on the structure of the heat recovery unit in question.

The heat recovery unit can be controlled as an integrated part of the house ventilation system. It is used to re-
cover heat in the low ventilation area for a number of days at the beginning of a batch. When a higher air output
is needed than the capacity of the heat recovery unit, the ordinary ventilation system will gradually take over.
The heat recovery unit has two fans. One of the fans removes warm, humid air from the house. The other fan
draws fresh, preheated air into the house.

The controller continuously adjusts the ventilation according to a calculation of the ventilation requirement.
Thus, the controller will increase or limit ventilation according to whether the inside temperature and air humidity
are too high or too low.

4.8.2 Parking of fans

With this function, fans can be taken temporarily out of service. This can, for example, be used in cold periods
where some fans are closed for insulation purposes, or if a fan is defective and awaiting repair.

We recommend that you only use parking for fans that are not actually in use. Otherwise, the ventilation control
cannot automatically adapt to the changed ventilation capacity.

If fans are parked and ventilation has been running at maximum for 5 minutes, the controller will give a soft
alarm to make you aware that you should activate the fans again.

Parking of fans must not be used as safety breaker in case of servicing the fan.

38 User Manual

Be aware that if you park all tunnel fans in a Combi-Tunnel system, the controller can still switch to tunnel
regulation of the ventilation - but without actually being able to use the tunnel fans.
This can be catastrophic for the animals.

4.8.3 Ventilation settings

Minimum ventilation

Climate | Ventilation
Minimum ventilation The lower limit for how little is ventilated in relation to the air requirement of the
animals.

The minimum ventilation function supplies the exact amount of air to the house, which ensures an acceptable
air quality. The function is particularly relevant in periods with cold weather when it is not necessary to ventilate
to keep down the inside temperature.
The controller calculates the necessary minimum ventilation according to the animals’ need for fresh air.
The animals' fresh air requirement varies according to the type of animal and weight. You must indicate the re-
quirement as cubic meters per hour (m3/h) per animal. You can find the correct figure in the technical literature
or ask your consultant if in doubt.
Note that the correct number of animals must be set in the menu Management | Animals.
Reduced minimum ventilation
In houses where a high minimum ventilation is required to avoid high CO2 and ammonia levels, it may be rele-
vant to use the Reduced minimum ventilation function. This function allows the minimum ventilation to follow the
outside temperature.

This function is an alternative to reducing the minimum ventilation via a CO2 sensor. However, if CO2 minimum
ventilation is also used, it will take precedence as long as the CO2 level determines the ventilation requirement.
Also see Technical Manual.
Maximum ventilation

Climate | Ventilation
Maximum ventilation Upper limit for how much of the system's capacity the controller can activate.

Maximum ventilation sets a limit to how much of the capacity of the ventilation system (in percentage) the con-
troller can activate. 100% ventilation corresponds to the animals’ calculated requirement, while ventilation utiliz-
ing the total system capacity may reach e.g. 160% (see also the section on extra ventilation).
The function can be relevant to use during very high outside temperatures. Ventilation utilizing the total system
capacity would make the inside temperature exceed the required temperature, as large amounts of warm air is
added. The function can also prevent young animals from being exposed to a level of ventilation which they do
not tolerate.
When you want to disregard the function, you should set the Maximum ventilation to the maximum value (fac-
tory setting 300 %). By doing so you ensure that there is not actually a limit on how much of the ventilation sys-
tem's capacity can be used.

4.8.4 Ventilation status

Stepless and MultiStep position

User Manual 39
DOL 534 • DOL 539

The air outlet in the house consists of partly one or several stepless exhaust units, partly groups of ON/OFF ex-
haust units. The stepless exhaust unit is variable, as the controller can adjust motor performance and flap open-
ing of the fan, while the fans in the other exhaust units are either on or off.
The ventilation system connects the stepless exhaust unit first. When the ventilation requirement exceeds the
capacity of the stepless exhaust unit, a group of the other exhaust units are connected and the stepless exhaust
unit decreases its output simultaneously. This way, the controller ensures stepless transition from one ventila-
tion level (MultiStep) to the next. If the ventilation requirement increases further, the stepless exhaust unit will
perform up to its maximum until it reduces its output when the next group of ON/OFF exhaust units is con-
nected.
All exhaust units in the the house bear a sign showing if it is a stepless or an ON/OFF exhaust unit. The latter
are numbered according to which MultiStep they belong. This way, it is possible to recognize the individual ex-
haust units and compare their actual output with the status that you can read in the Ventilation menu. This is
particularly relevant in connection with fault finding.
Shutter position
The flap position is a percentage indication of how much the flaps of both air inlet and air outlet are open. If you
are in doubt about the actual ventilation output, you can compare the reading of the Ventilation status in the
ventilation menu with the output that you can actually observe in the house. The percentage indications are rele-
vant particularly in connection with troubleshooting.

4.8.4.1 Cycle timer at minimum air intake

The objective of the cycle timer function is to enable the control of air currents in the house at a very limited ven-
tilation requirement. The function opens and closes the air inlets alternately, thus sending a more powerful air jet
through the house. This ensures a thorough replacement of housing air. See also the Technical Manual for the
house controller.
The cycle timer can also be displayed graphically as a card on
a page, see also Creating pages [} 18].

4.9 Side cooling

This section is relevant only to houses with side cooling systems.

Cooling is used in houses where ventilation alone cannot reduce the inside temperature sufficiently.
Cooling has the advantage over ventilation in that it can bring the inside temperature down below the outside
temperature. On the other hand, cooling will also increase the air humidity in the house.

MAX
Temperature

The combination of a high inside temperature and high air humidity can be life-threatening to the
animals. As cooling makes the house humidity increase, the controller automatically disconnects
cooling when the house humidity exceeds Humidity to stop side cooling (normally 75-85%, fac-
tory setting: 85 %).

The following sections describe the functions and setting options available in the side cooling menu.

It is possible to search for functions via the search function in the Settings menu. See section
Search in menus [} 22].

4.9.2 Start cooling

As a standard the climate controller will adjust for an increasing inside temperature by increasing the ventilation.
The cooling does not start until the climate controller is unable to maintain the temperature by ventilating.

4.9.2.1 Side cooling start based on ventilation level

The function Cooling before max ventilation makes it possible to start cooling at a lower ventilation level.
An early start of the cooling is particularly relevant in hot and dry areas. When you increase the ventilation level,
you get hot outdoor air into the livestock house. A smaller air volume needs cooling if you activate the cooling at
an earlier stage. It reduces both power and water consumption.
This feature is only available when outside and inside humidity sensor is installed.

With this setting the climate controller will continuously calculate the ventilation level at which the side cooling
must start.
The calculations are based on the current outside humidity and outside temperature and indicate a so-called
cooling potential. Also, see section Cooling potential [} 45].

At a cooling potential of 15 °C, cooling will, for example, start at 60 % of the maximum ventilation.

4.9.2.1.2 Cooling potential

The cooling potential is a way to describe how much the air temperature can be lowered by adding water-based
cooling.
The cooling potential for water-based cooling thus depends on the humidity and the outside temperature.

In general there is a higher cooling potential in hot areas than in cold areas. Furthermore, there will usually be a
very high cooling potential in areas with very low humidity.

Figure 13: The lower the outside humidity, the higher the cooling potential.

A rule of thumb states that for each 5 % increase in air humidity, the temperature drops by 1 °C.

4.10 Tunnel
This section is relevant only to houses with tunnel ventilation.

Tunnel ventilation is used at high temperatures. The air is let in through a tunnel opening at one end of the live-
stock house, and the air is exhausted through a number of wall fans at the other end of the house. This makes
the air move quickly in a lengthwise direction in the the house and the air therefore feels cooler.

Temperature

The tunnel ventilation cannot be activated until both the outside and inside temperatures are sufficiently high.

4.10.1 Cycle timer at tunnel ventilation

When tunnel ventilating at low ventilation requirement (e.g. below 0.8 m/s), the distribution of air in the house
can be ensured by means of a cycle timer. The controller will alternately switch the fans on and off. This will pre-
vent temperature differences.
The cycle timer can also be displayed graphically as a card on

4.10.2 Chill factor and chill effect

The chill factor reflects the fact that the cooling effect of the air is dependent on the age and breed of the ani-
mals. The younger the birds, the colder they feel the temperature at a given air velocity.

current chill factor.

The controller calculates which inside temperature is required in order to activate tunnel mode (only combi-tun-
nel).
• To make the change to tunnel at a lower inside temperature you must reduce the chill factor.
• To make the change to tunnel at a higher inside temperature you must increase the chill factor.

Enter the displayed code to change the house status.

The change takes place immediately when the fourth digit is en-

Active house
It may be an advantage to change the status to Active house the day before stocking the animals. This way the
controller has time to adapt the climate to the needs of the animals and to feed in the house.
The day number then switches to day 0, and the controller operates in accordance with the automatic settings.

Empty house
The status should not be changed to Empty house until the house has been depopulated.
Then the controller disconnects the adjustment and controls according to the in-between function Empty house.
This function protects the animals in case a house is set to Empty house by mistake.
If the house is to be completely closed, the settings of the in-between function Empty house must be reset. See

Program sequence
With time control, each in-between function can be set to start
at a specified time. It is thus possible to set a total sequence for
the in-between functions.

Soaking
Soaking will soak the house with water to loosen dust and dirt. This will not only reduce the amount of dust dur-
ing the subsequent cleaning but also make cleaning easier.
In soaking mode, stop ventilation to maintain the humidity in the house. Set the soaking system to run at inter-
vals (Cycle time) for a number of minutes (ON-time) during the total period (soaking time) which the soaking
process is to last.
Washing
While washing the house manually, ventilation must run again to start changing the air in the house.

Drying
Drying is a combination of ventilation and heat supply. The more heat is supplied to the the house, the faster it
dries.
Heating can be supplied as room heating or floor heating.
A desired temperature is set when room heating is used.
When floor heating is used, the percentage the floor heating system will operate at must be set. The floor heat-
ing stops when the inside temperature exceeds the temperature that has been set.
Disinfection
Disinfection is carried out manually by adding disinfectant to the water.
A certain temperature must be maintained in the house during disinfection in order for the disinfectant to have
optimal effect (often over 20 °C).
The house controller shuts off the ventilation system and supplies heat as needed to maintain the correct tem-
perature for disinfection.
Heating can be supplied as room heating or floor heating.
A desired temperature is set when room heating is used.
When floor heating is used, the percentage the floor heating system will operate at must be set. The floor heat-
ing stops when the inside temperature exceeds the temperature that has been set.

5.4.1 Empty house

Empty house
When batch status is Empty house (in the Management |
House data menu), the house controller will regulate according
to the settings for Empty house (set in the In-between func-
tions menu).
This function will maintain the air change in the house by allow-
ing ventilation to run at a fixed percentage (50 %) of the system
capacity. This is to protect the animals in case a house is set to
Empty house by mistake.

5.5 Ventilation boost

This section is only relevant to houses where ventilation boost is activated in the menu |
Technical | Installation | Manual installation | Management | Ventilation boost

68 User Manual
 DOL 534 • DOL 539

Ventilation boost is a function to improve the air quality in the house, the function can reduce CO2 and NH3 as
well as the amount of dust in the air. This is achieved by activating the function once or several times during the
day.
The air quality is improved by increasing the ventilation and activating an environment system which humidifies
the livestock housing with water (added oil is an option). This reduces the amount of dust and gas in the air in
the livestock housing. When the ventilation boost function starts, the climate controller gradually adjusts the cli-
mate to the settings of the function and then gradually reverts to the regular setting.
You can activate/deactivate the function's day program, which can have up to 8 active periods. You can also ac-
tivate the function manually if you enter the house outside one of the set periods. If you activate the function
manually there is no start adaption time, but the climate controller will still gradually revert to the regular set-
tings.
The function is not active when the house is set to Empty house.

6 Alarms
Alarms only work when the status is Active house.
The only exceptions are alarm test and alarms for CAN communication and temperature surveil-
lance for Empty house.

When an alarm occurs, the house controller will register the

alarm type and the time it occurred.
The information on the type of alarm will appear in a separate
alarm window together with a short description of the alarm situ-
ation.
The alarm relay is only trigged by hard alarms.
Soft alarms generate a pop-up in the display.
Red: active alarm
Yellow: active warning
Gray: deactivated alarm (alarm state ceased)
There are two types of alarm:
Hard alarm: Red pop-up alarm on the controller and alarm gen-
eration with the connected alarm units, e.g. a horn
Soft alarm: Yellow pop-up alert on the controller.
In the alarm menu, it is possible to select whether some climate
and production alarms are to be hard or soft.

The controller will also activate an alarm signal, which you can
choose to maintain.
The alarm signal will thus continue to sound until you acknowl-
edge the alarm. This also applies even if the situation that trig-
gered the alarm has stopped
Alarms maintained:
YES: The signal continues after the alarm situation has ceased.
NO: The signal stops after the alarm situation has ceased.

The controller can remind you of an on-going alarm situation

once you have acknowledged a hard alarm. This to ensure that
the cause of the alarm is handled.
Settings for reminders:
Alarm time: Setting how long after the alarm, the reminder is to
appear.

From the factory the low alarm is disconnected. The alarm limit is factory pre-set
at such a low level (5 %) that the alarm is only usually triggered upon intrinsic sen-
sor errors.
In the case of a high alarm (30 ppm) the house controller ventilates 100%.

6.4.10 Heat recovery alarm

Alarm settings | Climate | Heat recovery
Heat recovery unit The flap alarm for the heat recovery unit works in the same way as the other flap
alarms, see Inlet and outlet alarm [} 75].
The controller can generate an alarm if the temperature sensor in the air inlet is
short-circuited or disconnected.
The controller generates an alarm when the temperature in the air inlet is below
the set limit (-5 ̊C).

6.4.11 Dynamic Air Alarm

Alarm settings | Climate | Dynamic Air
Dynamic Air The Dynamic Air alarm may be due to a mechanical error in the fan, the pressure
sensor or the flap position. The house controller triggers an alarm if the measure-
ment of the ventilation output deviates from the calculated ventilation requirement.
Check the fan while it is running. Further troubleshooting must be carried out by
technically trained personnel.

6.4.12 Alarm for pop holes

Depending on the installation of the function, the controller will make an alarm for when the pop holes do not
open and/or close as required.
As long as the alarm is active, the controller will not open and close the pop holes. The user must acknowledge
the alarm, before adjustment is made again.

6.4.13 Winter garden alarms

Depending on the installation of the function, the controller will make an alarm for when access to the winter
garden does not open and/or close as required.
As long as the alarm is active, the controller will not open and close the access to the winter garden. The user
must acknowledge the alarm, before adjustment is made again.

6.4.15 Auxiliary alarms

It is possible to create a number of auxiliary alarms. For example, the controller may give an alarm from a con-
nected motor controller, a water pump or other equipment.
The alarms are set up in the menu Alarm settings | Auxiliary | Auxiliary alarms | Auxiliary alarm settings
Press Add to add a new alarm.
Press the field Name to give the alarm a name.
Press Category to select the category the alarm belongs to.
Set the control mode Hard, Soft or Disabled.
Set a delay, if required.
Set the activation to take place in the event of high or low input.
Select if the alarm should be active always or from a specific
day number.
To delete an auxiliary alarm, press the icon .

After creating the alarm, see the menu | Installation | Show connection for information about where to
connect the extra equipment.

6.4.16 Equipment status

When connecting monitoring equipment such as e.g. a current sensor for the individual components of the sys-
tem (stepless and MultiStep fans), it is possible to get an alarm which can indicate the possible fault type.
There are 3 alarm types:

Low alarm Possible equipment failure. The equipment may be disconnected by mistake.
Alarm due to missing current consumption. For example, MultiStep/stepless may
be activated and the power consumption too low, if the emergency stop at the fan
is activated.
High alarm The equipment shows signs of wear.
Alarm due to excessive current consumption.

78 User Manual
 DOL 534 • DOL 539

ON alarm The equipment is active, but should not be in relation to the controller's regulation.
Alarming due to current consumption, which should not be there. For example,
MultiStep/stepless may be activated and the power consumption too high, if there
is an emerging defect in the fan.
Alarms are only triggered when a limit has been exceeded for 5 minutes.

The alarms are set up to match the connected monitoring equipment. This is done in the menu Alarm settings |
Equipment status.
Select the alarm type Hard, Soft or Disabled.
Set voltage ranges for Low alarm, High alarm and ON alarm.
First read the current consumption during normal operation to
get an indication of the voltage ranges.

6.5 Emergency control

6.5.1 Emergency opening
The house controller has emergency opening as a standard function regardless of whether an actual emer-
gency opening is installed. As long as there is power, the controller will open the ventilation system 100 % in
case of a relevant alarm - even if it is cold outside.
The emergency opening can be activated by five types of alarms.
Activated by Side Tunnel (CT, T)
High temperature Yes
Absolute high temperature Yes Yes
Absolute high humidity Yes Yes
Pressure high alarm Yes Yes
Pressure low alarm (negative pres- Yes Yes
sure)
Pressure low alarm (positive pres- No No
sure)
Power failure Yes Yes

It may be an advantage to disconnect absolute high humidity in houses that are placed in areas with very high
outside air humidity and in situations when a technical sensor error emerges.

6.5.2 Temperature-controlled emergency opening

This section is relevant only to houses where temperature controlled emergency opening is in-
stalled.

Temperature controlled emergency opening is only triggered when the inside temperature exceeds the tempera-
ture setpoint for emergency opening (Emergency opening setpoint). You can read off the setpoint as an actual
temperature figure on the house controller’s display. The emergency opening is also triggered in the event of
power failure.

User Manual 79
DOL 534 • DOL 539

Emergency opening temperature

You can set the temperature at which emergency opening shall occur directly on the emergency opening’s ad-
justment knob. The setpoint can be read off in the display together with Temperature setpoint.
Warning at emergency temp.
The house controller can issue a warning that will flash in the display in the event of the Emergency opening
setpoint being too high in relation to the Temperature setpoint (inside temperature). This is especially relevant
at batch production and a falling temperature curve. This is where on an ongoing basis you must adjust the
Emergency opening setpoint downwards. However, too high a setting can also be caused by an error.
The warning function can be connected and disconnected. The setting here should be the number of degrees
by which the Emergency opening setpoint must exceed the Temperature setpoint for the controller to issue a
warning.
Battery alarm and battery voltage
Temperature controlled emergency opening has a battery that ensures that the emergency opening will open,
despite there being a power failure, if the inside temperature exceeds the Emergency opening setpoint.
You can read off the current and the lowest measured voltage on the battery. These readings indicate whether
you need to replace the battery or whether there may be a technical fault causing the battery alarm.
The house controller can trigger an alarm if the battery that operates emergency opening is not working.

Be careful not to set the Battery voltage limit too low, as this will actually deactivate the alarm.

6.5.3 Emergency inlet

This section is relevant only to houses where emergency inlets are installed.

The emergency air intake can be triggered by four types of alarms.

Activated by
Emergency inlet (temperature) Set
Absolute high temperature Connect or disconnect
Error temperature sensor Connect or disconnect
Power failure Always activate

Whether an inside temperature sensor error should trigger the emergency inlet depends on the general climate
conditions. If it is very hot, you could profit from using the function. However, if it is cold, you should consider the
necessity of using it and whether the animals will suffer.
The emergency Inlet has its own temperature setting Emergency Inlet, where the number of degrees are en-
tered for the Temperature setpoint and any Comfort temperature.
This setting makes it possible to open the air intake during a hot season where the air intake, under normal con-
ditions, is not activated by the normal high temperature alarm limit.
