Description
The Lennox Y8422 Outdoor Control Board 17122000A19408 is used to coordinate the work of the main unit elements, such as compressors, fans, sensors, and safety parts. It operates by taking into consideration inputs of a thermostat, internal sensors to control cooling cycles, defrosting instructions, and fan speeds. It is intended to be installed in the control compartment of the outside unit of residential and commercial HVAC systems and to the motors, relays, and sensors directly so they can be easily integrated. It helps the stability of the system and energy efficiency.
