The Honeywell Freeze Protection Control (FPC) is a low cost control designed to keep the air conditioning coil from freezing. The FPC is installed by simply snapping it onto the suction line just outside the evaporator coil. When the FPC senses temperature at 38°F, it breaks the circuit to the compressor relay, preventing a freeze-up. The FPC then remakes the compressor circuit at 48°F allowing ample time for the compressor to be off. This differential prevents short-cycling. During the period the compressor is off the indoor fan is still running using the cold coil to provide air conditioning.
