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
Motorized Fresh Air Damper
Commercial Room Ventilator
Economizer
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 open 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.
NOTE: The above vent systems are intake only without built-in exhaust capability . Building will likely require
separate field installed barometric relief or mechanical exhaust elsewhere within the conditioned space. Balancing
dampers in the return air grille may be required to achieve specified amount of outdoor air intake.
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.
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 available (except on 1.5 and 2-Ton models). The CRV and CRVS are
power open - spring return on power loss, and CRVP is power open and power close. Complies with ANSI/ASHRAE
Standard 62.1 “Ventilation for Acceptable Indoor Air Quality”.
ECONOMIZER - ECONWM-SeriesOPTIONAL
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.
• ECONWMT Equipment Building versions have extended air intake hood to deliver up to 100% of cooling rated airflow.
16" for ECONWMT-E2 or T2, and E3 or T3
18" for ECONWMT-E5 or T5
• ECONWMS Classroom versions have 3" air intake hood to deliver up to 75% of cooling rated airflow.
Standard Features:
•
Fully modulating
• Honeywell Direct Drive Hi-Torque Actuator
• No linkage required
• Simple single blade design
• Positive shut-off with non-stick gaskets
• Electronic DB and/or Enthalpy sensors depending upon version
• Honeywell JADE electronic economizer module with precision settings and diagnostics
• DB or Enthalpy economizer versions available
Energy Recovery Ventilator
WALL-MOUNT ENERGY RECOVERY VENTILATOR - ERVF OPTIONAL
The wall-mount energy recovery ventilator (ERV) is a highly innovative approach to meeting indoor air quality
ventilation requirements as established by ANSI/ASHRAE Standard 62.1. The ERV 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 ERV 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 ERV is designed to be internally mounted behind the service door in the W**A, W**H or W**L model wallmount units. It can be built-in at the factory or field installed as an option. ERVF-*3 and ERVF-*5 can be
independently adjusted for intake and exhaust rates.

CMC-15 is used.
8 ODT. Outdoor thermostat is adjustable from 0 to 50°F. It is suitable for use as a compressor cut-off thermostat.
9 DDC. 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 airflow, compressor status or filter status. Special economizer required; consult factory.
“V” control module should be ordered in conjunction with direct digital controller (DDC) model TCS24. Refer to DDC specification sheet S3280 for more information.
