Trane CNT08177 Defrost Board

The Trane CNT08177 Defrost Board is an essential part of HVAC systems particularly those that use heat pumps. It has a critical function in controlling the defrost cycle and the time and sequence in which the ice formed on the outside of the heat exchanger must be removed. This helps to avoid the system from being worked inefficiently and even damaged. The board uses timers, relays and sensors to trigger the defrosting process and also to monitor it. The CNT08177 board increases system competency, decreases energy expenditure, and improves the general durability of the HVAC equipment because of correct defrost cycle calibration.
