PRODUCT INFO
Air Handling Controller
The ICM6502 is a package unit heat pump control board designed to provide control of the compressor, reversing valve, auxiliary heat elements, the condenser and evaporator fans. The ICM6502 also accepts inputs from a thermostat, indoor coil temperature, outdoor coil temperature, outdoor ambient temperature, indoor room temperature and a shutdown switch (front desk). The ICM6502 provides compressor protection from short cycling with an anti-short cycle timer and low ambient lockout. A built-in defrost cycle will protect the outdoor coil from freezing up when in heating mode.
