Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.
Based on 75°C copper wire. All wiring must conform to the National Electrical Code (NEC) and all local codes.
These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electric Code (latest revision), article 310 for power conductor sizing.
Caution: When more than one field power conductor 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 3 conductors are in a raceway.

Ventilation System Packages
Bard Wall-Mounts are designed to provide optional ventilation packages to meet all of your ventilation and indoor air quality requirements.
All units are equipped with a barometric fresh air damper as the standard ventilation package. All ventilation packages can be built-in at the factory,
or field-installed at a later date.
BAROMETRIC FRESH AIR DAMPER - BFAD
STANDARD
The barometric fresh air damper is a standard feature on all models. It is installed on the inside of the
service door and allows outside ventilation air, up to 25% of the total airflow rating of the unit, to be
introduced through the air inlet openings and to be mixed with the conditioned air. The damper opens
during blower operation and closes when the blower is off. Adjustable blade stops allow different amounts
of outside air to be introduced into the building and can be easily locked closed if required.
Barometric Fresh Air Damper
BLANK OFF PLATE - BOP
OPTIONAL
A blank off plate is installed on the inside of the service door. It covers the air inlet openings, which
restricts any outside air from entering the unit. The blank off plate should be utilized in applications where
outside air is not required to be mixed with the conditioned air.
MOTORIZED FRESH AIR DAMPER - MFAD
OPTIONAL
The motorized fresh air damper is internally mounted behind the service door and allows outside ventilation
air, up to 25% of the total airflow rating of the unit, to be introduced through the air inlet openings and to be
mixed with the conditioned air. The two position damper can be fully opened or closed. The damper blade
is powered open by a 24VAC motor with spring return on power loss. The damper can be controlled by
indoor blower operation or can be field connected to be managed based on building occupancy.
Motorized Fresh Air Damper
NOTE: The above vent systems are without exhaust capability. May require separate field installed
barometric relief and/or mechanical exhaust elsewhere within the conditioned space.
COMMERCIAL ROOM VENTILATOR - CRV
OPTIONAL
The built-in commercial room ventilator is internally mounted behind the service door and allows outside
ventilation air, up to 50% of the total airflow rating of the unit, to be introduced through the air inlet
openings. It includes a built-in exhaust air damper.
Commercial Room Ventilator
The commercial room ventilator (CRV) is a simple and innovative approach to improving the indoor air
quality by providing fresh air intake and exhaust capability through the CRV. The damper can be easily
adjusted to control the amount of fresh air supplied into the building. The CRV can be controlled by indoor
blower operation or field controlled based on room occupancy. Two versions are available: the CRVS is
power open - spring return on power loss; the CRVP is power open and power return. Complies with
ASHRAE Standard 62.1 “Ventilation for Acceptable Indoor Air Quality.”
ECONOMIZER - EIFM
OPTIONAL
The built-in economizer system is internally mounted behind the service door and allows outdoor air to be
introduced through the air inlet openings. The amount of outdoor air varies in response to the system
controls and settings defined by the end user. It includes a built-in exhaust air damper. The economizer
is designed to provide “free cooling” when outside air conditions are cool and dry enough to satisfy cooling
requirements without running the compressor. This in turn provides lower operating costs, while extending
the life of the compressor.
Economizer
Energy Recovery Ventilator
Standard Features:
• One Piece Construction - Easy to install with no mechanical linkage adjustment required.
• Exhaust Air Damper - Built in with positive closed position. Provides exhaust air capability to
prevent pressurization of tight buildings.
• Actuator Motor - 24 volt, power open, spring return with built in torque limiting switch.
• Proportioning Type Control - for maximum “free cooling” economy and comfort.
• Moisture Eliminator & Prefilter - permanent, washable aluminum construction.
• Enthalpy Control - adjustable to monitor outdoor temperature and humidity.
• Minimum Position Potentiometer - adjustable to control minimum damper blade position for
ventilation purposes.
• Mixed Air Sensor - to monitor outside and return air to automatically modulate damper position.
WALL-MOUNT ENERGY RECOVERY VENTILATOR - WERV
OPTIONAL
The wall-mount energy recovery ventilator (WERV) is a highly innovative approach to meeting indoor air
quality ventilation requirements as established by ASHRAE Standard 62.1. The WERV allows from 200
to 450 CFM (depending upon model) of fresh air and exhaust through the unit while maintaining superior
indoor comfort and humidity levels. In most cases, this can be accomplished without increasing equipment
sizing or operating costs. Heat transfer efficiency is up to 67% during summer and 75% during winter
conditions.
The WERV consists of a unique “rotary energy recovery cassette” that provides effective sensible and
latent heat transfer capabilities during summer and winter conditions. Various control schemes are
addressed - including limiting ventilation during building occupancy only.
The WERV is designed to be internally mounted behind the service door in the WA, WH or WL model wall
mount units. It can be built-in at the factory or field installed as an option. (See Form F1403 for complete
performance and application details.)

Compressor control module has adjustable 30-second to 5-minute delay-on-break timer. On initial power-up, or any time the power is interrupted, the delay-on-make will be 2
minutes, plus 10% of the delay-on-break setting. There is no delay-on-make during routine operation of the unit. The module also provides the lockout feature (with 1 retry) for high
and/or low-pressure controls, and a 2-minute timed bypass for low-pressure control.
LAC. Low ambient control permits cooling operation down to 0°F.

Outdoor thermostat is adjustable from 0 to 50°F. It is suitable for use as a compressor cut-off thermostat.
Incorporates 4 additional sensors: discharge air temperature, indoor blower airflow, compressor current, and dirty filter. These sensing devices function to input analog
data such as temperature, as well as digital data such as air flow, compressor status or filter status.
"V" control module should be ordered in conjunction with direct digital controller (DDC) model TCS22. Refer to DDC specification sheet S3280 for more information.
