Honeywell DB7110U1000 Universal Heat Pump Defrost Control
Universal Defrost Control for Single Stage On/Off Heat Pumps. It provides control of the outdoor equipment; compressor contactor, reversing valve, and outdoor fan in response to thermostat requests and air and coil temperatures. It also controls the indoor auxiliary heat source that is used during defrost operations and often as a second stage of heat. A defrost cycle is triggered based on outdoor air and outdoor coil temperatures that are measured using included temperature sensors.
