This temperature control is built to withstand the rigorous duty cycles of residential and light commercial air handlers and furnaces

The Ranco A30-2209 Control is a heavy-duty

or insufficient combustion air causing flames to roll out the front of the burner

and industrial duct furnaces

This is achieved by either cycling the thermostat below room temperature or removing the 24V power source for at least 5 seconds to clear the ignition lockout code

Carrier HH18HA282 Thermostat/Sensor 328140-751 This temperature control is builtThe Carrier HH18HA282 is a high precision defrost thermostat sensor engineered for Carrier, Bryant, and Payne heat pump systems. This OEM replacement part, also identified by manufacturer number 3NT01L 04002, is a critical tube mount sensor designed to monitor evaporator coil temperatures.
