Description
The Nordyne 624769R Interface Board is an electronic component that connects inputs from the field to the HVAC systems. This furnace, air handlers and packaged units take signals fed by thermostats, sensors and user controls and convert them into coordinated instructions to be passed to the blowers, gas valves, ignition sequences, and safety elements. It is installed in the electrical compartment within the unit and is linked to the wiring harness, which gives the system a structured routing and logic of the control signals to act in the right way depending on the operating conditions.
