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 2% 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 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 2% 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 2VAC 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 % 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 available (except on. 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 2. 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 - 2 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 - ERVF OPTIONAL The wall-mount energy recovery ventilator (ERVF) is a highly innovative approach to meeting indoor air quality ventilation requirements as established by ANSI/ASHRAE Standard 2.. The ERVF allows from to 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 7% during summer and 7% during winter conditions. The ERVF 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 ERVF 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-* and ERVF-* can be independently adjusted for intake and exhaust rates. Manufactured under U.S. Patent Nos.,,7;,,7 Form No. S2- Supersedes S2- Page of 2

The module also provides the lockout feature (with 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 F. ALR The alarm relay has a set of normally open and normally closed dry contacts to provide the ability to signal a condition of shutdown on either high or low pressure controls. SK PTCR start kit is standard with all -A single phase models only. Increases starting torque 2-x. Must be disconnected if SK or SK is used. Is not used or available for -B or -C three phase models. 7 Start capacitor and potential relay start kit can be used with all -A single phase models. Increases starting torque 9x. Not used for -B or -C three phase models. Do not use if CMC- is used. Use SK for WA-A only. Use SK for WA-A and W9A-A only. ODT. Outdoor thermostat is adjustable from to F. It is suitable for use as a compressor cutoff thermostat. 9 DDC. Incorporates 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 w/direct digital controller (DDC) model TCS2. Refer to DDC specification sheet S2 for more information. Form No. S2- Supersedes S2- Page of 2
