Carrier HH18SA261 Defrost Temperature 320735-701 Common Questions What wire isThe Carrier HH18SA261 Defrost Thermostat is a critical inductive component engineered for Carrier, Bryant, and Payne heat pump systems. This dual purpose sensor utilizes a bi metal disc temperature control mechanism with a specific L80F 50 calibration, meaning it opens the circuit at 80F and closes it at 30F (50F differential). Designed as a direct replacement for the HH18SA261A, this SPST defrost switch monitors outdoor coil temperatures to initiate
