Carrier HH63AW001 Economizer Control

The Carrier HH63AW001 Economizer Control is an energy saver if installed in suitable Carrier rooftop HVAC units. To determine if cooling with outside air is more efficient than running the mechanical cooling system, it measures the outside temperature and humidity. The economizer control saves energy by allowing outside air to be used in the building during periods when outside temperature is relatively low. With dimensions of 4.5 x 4.1 x 1.5 inches this small device may potentially cut energy consumption by half without causing discomfort in buildings.
