Description
The York S1-373-49824-003 2-Stage Circuit Board without Communication is a control component that regulates heating, and cooling sequences by coordinating system components in HVAC systems in residential and light commercial furnace units. It operates by receiving input signals through thermostats and sensors and controlling outputs in two levels of operation, which include blower motors, ignition systems, and safety parts. Constructed as a substitute control board, it can be installed in the control compartment of the unit and interconnected with the existing wiring harnesses. It enables staged operation control, and efficient system response and aids in maintaining stable performance.
