The “OAS” Outside Air Sensor allows precise real time monitoring of the Outside Air temperature on your Zoned HVAC system. The Optional “OAS” wires directly into the BMPlus series, UZC4 series or UT3000 control panels allowing the Control System to monitor the outside air temperature. Using the adjustable potentiometer on the Control Panel or the LCD menu, the installer can set the desired outdoor temperature changeover setting, to engage supplemental or backup heating systems.
The OAS comes standard with the HK2000 Economizer System. Refer to the Hk2000 Technical Bulletins for the specific Outside Air Features & Functions provided, with that product.
