Defrost Control Board
DETAILS:
The ICM350 Defrost Board is a 3-in-1 replacement board for Carrier HK32EA001, HKEA003 and HK32EA008 boards. Special circuitry helps reduce noise disturbances when entering and exiting the defrost sequence on the 003 and 008 applications.
- Adjustable 30, 60, 90, and 120 minute timing sequences
- Speedup jumper for quicker testing and troubleshooting
- Brownout monitoring
- Microcontroller precision timing
- Time and temperature termination
- Quiet Shift : Reduces noise disturbance when entering and exiting the defrost sequence (HK32EA003 & HK32EA008)
- 5 minute anti short cycle delay (HK32EA003 & HK32EA008)
- Optional random start timer (HK32EA003 & HK32EA008)
