Trane CNT5010 Defrost Control Board

The Trane CNT5010 Defrost Control Board plays an essential role in the control of commercial heat pumps for efficiency. It is a cyclic process of operation necessary to defrost the body, and in turn, operate effectively. This board checks refrigerant pressures, outside air temperature and superheat to decide when a defrost cycle is needed. It energizes the required parts like electric heaters, reversing valve, fans during the defrosting process to eliminate ice formation on the outside coil. This avoids the occurrence of low airflow, high heat exchange, and high system performance.
