Fossil Fuel Kit. The AFE18-60A control is designed for use where the indoor coil is located
above/downstream of a gas or fossil fuel furnace when used with a heat p ump. It will operate
with sing le and two stage heat pumps and single and two stage furnaces. The AFE18-60A
control will turn the heat pump unit off when the furnace is turned on. An anti-short cycle feature
initiates a 3 minute timed off delay when the compressor goes off.
