Description
The York S1-33109150000 2/4 Stage Control Board Kit is a multi-stage furnace control board that is used to control ignition, blower sequencing and safety operation in Simplicity 1A heating and cooling systems. It receives signals from thermostats and sensors, activating burners, regulating the work of the blower in two or four stages of heat, and controlling limits and safety measures to ensure proper cycling. It coordinates the operation of the systems in residential furnaces and air handlers. Its logic and diagnostics built-in enable it to maintain temperature and safe and efficient operation in normal heating cycles.
