ICM Controls ICM6502 Package Heat Pump Control

Product description

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.

The ICM6502 contains all functions to operate a package heat pump. Thermostat and temperature switches are provided, and on-board switching of the compressor, reversing valve, condenser and evaporator fans. The control contains auxiliary heat outputs as well.

Features :

• Power interruption protection for the compressor
• Random Start delay
• 6-minute anti-short cycle timer protects compressor from rapid short cycling
• Two stages of heating (compressor & auxiliary back up heat)
• Low outdoor ambient compressor lockout (cooling/heating)
• Steady state cooling
• Low indoor coil temperature cooling shut down
• Low outdoor coil defrost lockout (defrost mode)
• Low indoor room ambient (RS) auxiliary heat mode
• Front Desk shut down switch input
• Speed up test mode reduces timing for field testing of the board
