Description
The NORITZ NPJ231 Control Board is an electronic controller used to monitor the activities of the element and regulate communication among the internal components in HVAC systems. It uses a printed circuit board to receive signals from sensors and safety parts, processes that information, and sends instructions to the ignition components, valves, and other controls while working with water heaters and hydronic HVAC systems with the CB-PCB control board layout. It is mounted in the equipment control compartment to which wiring harnesses are attached to the circuit terminals and power supply leads.
