/////// Unit Modes of Operation
Cooling Operation:
The Bard MULTI-TEC Series products offer single-stage compressor cooling operation using R410A refrigerant. Copper tube/Aluminum
hydrophilic green fin coils provide high efficiency and easy serviceability. Scroll compressor technology delivers years of quiet, reliable
operation. Economizer vent options are available for increased energy efficiency during cooling operation when outdoor conditions are
favorable.

Optional Heating Operation:

The Bard MULTI-TEC Series products offer optional single or two-stage heating operation using resistance heaters. Circuit breaker disconnect
protection is standard in all units equipped with electric heat.

Optional Free Cooling Ventilation:

The Bard MULTI-TEC Series offers an optional economizer free cooling vent used when cooling is necessary, with mild outdoor conditions.
Economizers use outdoor air to cool equipment and electronics inside a structure, saving energy and reducing runtime on the refrigerant
system, extending unit life. An outdoor temperature and humidity sensor measures outdoor conditions, and user-adjustable settings are
provided, including outdoor temperature, relative humidity, and dewpoint. Building exhaust air relief is provided through the vent assembly,
providing slight building pressurization. If necessary, a minimum blade position setting is available for a constant outdoor air supply.
Emergency cooling operation is available with a user-adjustable alarm to open the damper and bring outdoor air into the shelter when the
outdoor temperature is cooler than the temperature indoors. The ventilation shutdown feature forces the damper to close during an external
emergency alarm.

Optional Mechanical Dehumidification (Hot Gas Reheat) Operation:

Mechanical Dehumidification provides an energy-efficient way to remove humidity from the indoor air stream without overcooling or
overheating the indoor space. The Bard W30 through W72 Series products offer optional dehumidification operation that removes moisture
from the air entering the unit. A three-way valve, reheat coil, and electronic expansion valve (EEV) are standard with all models. The
dehumidification circuit incorporates an independent heat exchanger coil in the supply air stream. This coil reheats the supply air after
it passes over the cooling coil without requiring the electric resistance heater to be used for reheating purposes. This results in very high
mechanical dehumidification capability from the air conditioner on demand without using electric resistance reheat (electric heat is available
for heating purposes). Airflow during dehumidification is reduced, resulting in additional latent capacity operation.

Optional Electrical Dehumidification (Electric Heat Reheat) Operation:

Units with a 15kw electric heat option are available that operate compressor cooling to remove moisture from the indoor airstream and operate
electric heat to re-warm the leaving air temperature. Review state and local codes from a compliance standpoint before ordering this option.

Filtration and Indoor Air Quality:

Providing the best air filtration solution is important to occupants and equipment inside a room or structure. Bard provides several filter
options based on MERV filtration, and also other solutions to improve indoor air quality.

Increased Latent Cooling Operation (Balanced Climate Mode):

Additional moisture can be removed during cooling operation by reducing the indoor fan speed. This feature is user-selectable and is operated
based on a user-adjustable indoor humidity setpoint. Using this feature, when humidity levels are higher than normal inside the building, the
indoor fan can slow down to reduce moisture levels while cooling the space. When cooling is not required for equipment inside the building,
but humidity reduction is required, dehumidification operation is recommended.

Increased High Sensible Cooling Operation (Hi Sensible Mode):

Increasing the indoor fan speed is possible for additional sensible cooling capacity during cooling operation. This feature is user-selectable
and is operated based on a user-adjustable indoor humidity setpoint.

Low Outdoor Temperature Cooling Operation:

Equipment cooling often requires indoor areas to remain cool regardless of outdoor temperature. If your application requires operation of the
compressor to provide cooling below 65° outdoor conditions, then just like any other HVAC system, a low ambient control (LAC) is used. The
LAC will help maintain higher refrigerant pressure during compressor operation at lower outdoor temperatures. This is achieved by limiting
outdoor fan operation based on system pressure. As temperatures decrease outdoors, outdoor fan use will continue to decrease. Applications
that require cooling functionality from 0°F to -40°F outdoor temperatures will require an economizer for cooling operation.

High Outdoor Temperature Cooling Operation:

The Bard WA Series products are designed and tested to function in higher outdoor temperature areas. Wall-Mount products utilize large,
efficient condenser coils with high airflow condenser fan systems to save energy and lower high-side refrigerant pressures. It is always
important to follow all clearance guidelines supplied in the unit dimension section of this specification and additional information provided
in the user manual. Properly cleaning the condenser coil using a regular maintenance schedule and filter changes will help maintain unit
operation during high outdoor ambient temperatures.

/////// Indoor EC Motor Blower Speeds
Indoor airflow is measured in Cubic Feet per Minute (CFM) and will vary based on static pressure created by supply duct work, return duct work, unit filter type,
deflection of the air by the supply grille, or any other restriction of air entering or leaving the unit. The indoor fan motor of the WA series product has the capabil-
ity of running at multiple speeds. Indoor blower speed is selected inside the control panel area using the speed tap terminal block.

Blower and Vent Only Speed: The WA series uses this speed when fan only or ventilation operation is used. See airflow performance chart for CFM amount.

Balanced Climate Speed: The WA series uses this speed when the Balanced Climate Mode is enabled or mechanical dehumidification option (M) is used. The
Balanced Climate speed reduces unit airflow by approximately 30% which increases moisture removal (latent capacity) during cooling operation. Units with the
hot gas reheat dehumidification option also use this speed to increase moisture removal when running in dehumidification mode. Unit capacity performance
when using Balanced Climate can be calculated using the -30% capacity multipler factor provided in the Cooling Application Data. Unit capacity performance
for hot gas reheat dehumidification units can be found in the Dehumidification performance supplimental manual #7960-811. See airflow performance chart for
CFM amount.

Balanced Climate can be used for duct free and ducted applications below ESP total static shown in indoor airflow performance charts. Balanced Climate pro-
vides increased moisture removal during the cooling cycle, but is not a replacement for optional mechanical dehumidification. Optional mechanical dehumidifi-
cation provides moisture removal without significantly cooling the space being conditioned. Mechanical dehumidification is highly recommended for applications
requiring indoor humidity control or applications with a varying indoor heat load.

LO Speed: The WA series uses this speed by default when using standard cooling or heating operation. Lo Speed provides the optimal airflow amount for normal
use. See airflow performance chart for CFM amount.

HI Speed: The WA series uses this speed when the High Sensible Mode is enabled. See airflow performance chart for CFM amount. HI speed provides maximum
unit airflow per the airflow performance chart.

/////// Indoor Airflow Static and Unit Performance

The airflow amount that passes through the unit is very important when considering cooling capacity and proper unit operation. Restriction of the amount of
air passing through the unit is called external static pressure (ESP). As the amount of air passing through the unit is restricted, the ESP value increases. This
will have a direct impact on how heating and cooling equipment performs when used in an application. It is important to have a professional HVAC contractor,
distributor, or technician complete a duct static calculation if supply or return ducts are used with the WA series unit. Unit filter static must also be calculated
into the total ESP value.

Supply Duct Static: Supply duct static will include duct work connected to the unit supply opening, supply registers, filtration installed in the supply duct, or any
other device in the supply airstream that will restrict airflow. All ducts must be sealed to reduce duct air leakage, and flex duct work must not include restriction
due to installation. Duct static must be calculated by a HVAC professional and include all factors of the duct design.

Return Duct Static: Return duct static will include duct work connected to the unit return opening, return registers, filtration installed in the return duct, or any
other device in the return airstream that will restrict airflow. All ducts must be sealed to reduce duct air leakage, and flex duct work must not include restriction
due to installation.Duct static must be calculated by a HVAC professional and include all factors of the duct design.

Unit Filter Static: The WA series uses a unit filter installed before the indoor blower assembly that filters both indoor air from the room and outdoor air entering
through the ventilation device. When additional filtration is required (higher MERV rating), additional static will need to be added to the total external static
pressure (ESP). The following chart is to be used to estimate additional static pressure for a installed clean filter.

FILTER CODE FILTER MERV RATING FILTER STATIC INCHES WC. FILTRATION LEVEL
X MERV 2 0” WC Low Filtration, 1” Thickness Disposable Media.
W MERV 2 -.02” WC Low Filtration, 1” Thickness Permanent Media.
P MERV 8 .03” WC Average Filtration, 2” Thickness Pleated Disposable Media.
M MERV 11 .05” WC Above Average Filtration, 2” Thickness Pleated Disposable Media.
N MERV 13 .08” WC High Filtration, 2” Thickness Pleated Disposable Media.

Calculating Total External Static Pressure: Supply duct static, return duct static, unit filter static, and any other source of additional static pressure are added
together. Once this is calculated, the actual unit airflow amount can be reviewed by using the Indoor Airflow CFM charts provided.

Total External Static Pressure Calculation:

Supply Duct Static + Return Duct Static + Filter Static + Additional External Static = Total External Static Pressure (ESP)

Non-Ducted Applications: Applications that do not include supply or return ducts inside the structure, use Bard supplied supply and return louvers, and do not
have additional sources of external static will typically reflect rated airflow amounts shown in the Indoor Airflow CFM charts. Additional filter static must still be
added as necessary to the rated airflow total external static pressure (ESP). Field supplied supply and return louvers must match Bard supplied supply and return
louvers to achieve shown in the Indoor Airflow CFM charts. Adjustment of 4-way deflection supply louver may effect unit supply airflow. See louver deflection and
throw characteristics provided in this document.

Notes: • Unit compressor cooling operation below 60°F requires a Capacity Multiplier Factors

• 1000 BTUH = .29307 kW

• Outdoor air temperatures provided are an average of the

Capacity Multiplier Calculation: Capacity multipliers are used to estimate unit capacity performance when airflow rates are decreased or
increased compared to rated airlow. Rated airflow is the standard CFM amount used for capacity and efficiency calculations. Airflow rates
may be effected by external static pressure (ESP) from supply ducts, return ducts, advanced filter options, or use of additional blower speeds.
See unit airflow charts for additional information on unit airflow at different indoor blower speeds, filter static levels, and indoor airflow using
Balanced Climate operation.
Example: Due to additional supply duct static, the actual supply airflow CFM for a installed W72 unit is 10% lower than the rated airflow
shown in the blower performance chart. We want to know the actual BTUH amount of the unit at 85/72°F indoor and 100°F outdoor
temperature for this application. The following formula will be used to calculate actual unit BTUH at the new supply airflow CFM amount:
Rated unit BTUH capacity x capacity multiplier factor = actual unit BTUH capacity.
Example: 75,000 rated Total BTUH x .97 capacity multiplier = 72,750 actual Total BTUH.
Example: 47,300 rated Sensible BTUH x .95 capacity multiplier = 44,935 actual Sensible BTUH.

 Maximum size of the time delay fuse or circuit breaker for protection of field wiring conductors.
 Based on 75°C copper wire. All wiring must conform to the National Electrical Code and all local codes.
 These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest version), Article 310
for power conductor sizing.

CAUTION: When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special attention to Note 8 of Table 310
regarding Ampacity Adjustment Factors when more than three current carrying conductors are in a raceway.

IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses and conductor wires in accordance
with the National Electrical Code and all local codes.
Note: MOCP (Maximum Overcurrent Protection) value listed is the maximum value as per UL 1995 calculations for MOCP (branch-circuit conductor sizes in this chart are based
on this MOCP). The actual factory installed Overcurrent Protective Device (Circuit Breaker) in this model may be lower than the maximum UL 1995 allowable MOCP

Vent Type Description
Code

B No Ventilation Unit does not include intake or exhaust openings for ventilation.

Free flow economizer. Enthalpy, Dew Point, or Dry Bulb economizing settings. A field installed 7” hood is re-
5 Economizer
quired on each side of the unit. The economizer is not a field installed option.
* Note: Ventilation options are not field installable.

“B” Vent Code Option – No Vent

This unit is constructed without the economizer vent option and the air intake and exhaust openings are removed. The no vent option may be
utilized when outside air intake is not desired or required by local codes.

“5” Vent Code Option – Free Cooling Economizer

The free cooling economizer uses a 2-10V High torque actuator to control the intake and exhaust damper. Intake air is pre-filtered before
entering the unit. A large exhaust air path is provided to reduce room pressure to slight positive pressurization during economizer operation. All
dampers include rubber seals for positive shutoff when the economizer is not being operated. All operation is controlled by the unit logic board.

Unit Software Economizer Features:

• Standard dry bulb outdoor temperature control of economizer operation.
• Optional wet bulb outdoor enthalpy control of economizer operation. Humidity is measured in either %RH or Dew point.
• Passive Dehum: Economizer operation can be disabled if humidity levels measured by the LC6000 reach the indoor maximum humidity
set point. The default passive indoor humidity set point is 70%RH*.
• Emergency Vent: When NO/NC* contacts are energized in the LC6000, the economizer blades are fully opened and the evaporator Fan is
activated.
• Emergency Off: When NO/NC* contacts are energized in the LC6000, the economizer blades are closed, and unit operation is disabled.
• Emergency Cool: When high temp alarm 2 is active in the LC6000 due to a High temperature event in a zone, the economizer blades are
fully opened and the Evaporator Fan is activated when the return air temperature is above the outdoor air temperature.
*Default setting.

Note: Fire suppression systems that use gases to flood an area may require economizer shutdown within 30 seconds of a smoke/fire event.
A signal from the LC6000 controller to close all dampers and disable unit operation can take over a minute (time will vary based on daisy
chain connections). A relay must be installed to break the 24VAC power supply output from the low voltage transformer in each unit in order
to shorten the blade closure time and disable unit operation.

/////// Controller Overview
The MULTI-TEC® unit has many controls options to choose from. Selection of the right controls option will depend on how many units
are being controlled, if remote communication via modbus or webpages is required, and how many alarms are needed to indicate
building conditions or unit characteristics.

Here are a few typical MULTI-TEC controller setups:

- The LC6000 is used to control 1 to 14 units in a building with 1 to 3 different climate zones. Both temperature and humidity are
monitored. Each zone can monitor a temperature average using a wall or ceiling mounted sensors and unit return sensors. Multiple dry
contact alarms are available from the LC6000 controller. Modbus and webpage remote access is available. Review wiring requirements
in LC6000 specification sheet.

- The th-Tune is used to control 1 unit in a building with 1 climate zone. Temperature is monitored with a sensor built into the th-Tune.
A single dry contact alarm is available from the MULTI-TEC to indicate a unit failure. A TEC-EYE diagnostic tool ships with the th-
Tune when ordering the installation kit Bard part #8620-264. Modbus and webpage remote access are not available. 18ga. to 22ga.
connection wire is field supplied. The th-Tune is wall-mounted or can be mouted to a junction box inside the zone.

- The PGD is used to control 1 unit in a building with 1 climate zone. Temperature is monitored by the return air sensor in the unit
(PGD Kit part #8620-306), or can use a remote temperature sensor (PGD Kit part #8620-307). The PGD includes a wall-mounted
enclosure. A single dry contact alarm is available from the MULTI-TEC to indicate a unit failure. Modbus and webpage remote access
are not available. An RJ11 cable is provided to connect the PGD to the MEGA-TEC and the PGD must be within 20ft. of the unit

TEC-EYE Main Setpoint Menu

The setpoint screen allows for a temperature setpoint to be adjusted and used without using the LC6000 or th-Tune controller.
When the MULTI-TEC unit is connected to the LC6000 or th-Tune, the temperature setpoints in the controller will override the
setpoints in the unit setpoint menu. If the PGD is used, these will be the setpoints for unit operation.

Set Temp.
A cooling and heating setpoint can be entered in this menu. Once entered, the unit will operate using
the setpoints based on the return air temperature sensor. When a LC6000 or th-Tune is connected to
the MULTI-TEC unit, these settings will no longer apply. If the MULTI-TEC loses communication with
the LC6000 or th-Tune, the last setpoints recieved from the controller will be used when running in
orphan mode until communication with the controller is restored.

Data Log Menu

The data event log screen records and displays any active or recorded alarms or events that have occured since the alarms
were cleared.
