SAS Supply Air Sensor

The SAS Supply Air Sensor allows precise real time monitoring of the Supply Air temperature on your Zoned HVAC system. The SAS wires directly into the BMPlus, NCM300, EWC-300 or UZC series control panels and senses the supply air temperature in both heating and cooling modes. Using the adjustable potentiometers on the control panel, the installer can set the desired temperature limit set points on most EWC zoned HVAC systems. This will protect the HVAC equipment from frozen coils, excessive sweating, or short cycling the furnace/heat pump on high limit or pressure
