Continuous CFM is the total air being circulated during continuous (manual) fan mode. Will occur automatically with a call for Y1 signal from thermostat. Will occur automatically with a call for Y2 signal from thermostat. Will occur automatically with a call for W signal from thermostat. Constant CFM of Variable Speed Motor should maintain mid-rise temperature differential through range of allowable static. Ventilation System Packages 125, BTU Input Bard Wall-Mounts are designed to provide optional ventilation packages to meet all of your ventilation and indoor air quality requirements. All ventilation packages can be built-in at the factory, or field-installed at a later date. BLANK OFF PLATE - WGSBOP STANDARD 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. COMMERCIAL ROOM VENTILATOR - WGSCRVMP-5 OPTIONAL The built-in commercial room ventilator is internally mounted behind the service door and allows outside ventilation air, up to 5% of the total airflow rating of the unit, to be introduced through the air inlet openings. It includes a built-in exhaust air damper with integral bug screen. Automatic control is integrated to maintain desired ventilation air at the various supply airflows while on Stage 1, Stage 2 or ventilation modes of operation. 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. The CRV is power open - spring return on power loss. Complies with ANSI/ASHRAE Standard 62.1 Ventilation for Acceptable Indoor Air Quality. CO 2 Sensor Ready: WGSCRVMP-5 is designed for CO 2 based on ventilation control by simply wiring in a field installed CO 2 sensor if desired. ECONOMIZER ENERGY RECOVERY VENTILATOR ECONOMIZER - WGSJIFM-5 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. 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. Honeywell JADE electronic economizer module with precision settings and diagnostics. Mixed Air Sensor - to monitor outside and return air to automatically modulate damper position. WALL-MOUNT ENERGY RECOVERY VENTILATOR - WGSERV-5 OPTIONAL The wall-mount energy recovery ventilator (WGSERV-5) is a highly innovative approach to address indoor air quality ventilation requirements as established by ANSI/ASHRAE Standard The WGSERV-5 allows up to 45 CFM (depending upon speed setting) 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 74% during summer and 8% during winter conditions. The WGSERV-5 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 WGSERV-5 is designed to be internally mounted behind the service door in the WGS Gas/Electric units. It can be built-in at the factory or field installed as an option. WGSERV-5 can be independently adjusted for intake and exhaust rates. NOTE: See Page 4 for WGSCRV Performance Data & Page 5 & 6 for WGSERV Performance Data Page 3 of 12

7 Important Information Concerning Altitude Impact on Heating Input Ratings Heating input, and thus heating output, decreases with altitude. No orifice change is required up to 6, feet elevation and derate occurs naturally due to altitude impact. Natural gas models may require orifice change based on BTU content of gas. See Natural Gas Orifice and Altitude Tables on next page for details. For Propane Gas see the Propane Gas Conversion Table below. Above 6, feet elevation orifice changes are required, and capacity reductions are a function of altitude impact and orifice change. Pressure switch change is required above 6, feet elevation. For Natural Gas see the Orifice and Altitude Tables on next page. For Propane Gas see the Propane Gas Conversion Table below.

HPC. High pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note. LPC. Low pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note. CCM. Compressor control module has adjustable 3-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 1% 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 F. SK. 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.
