Description
The Friedrich 67400371 Main Printed Circuit Board is a necessary part of the HVAC and is responsible for managing and regulating multiple processes of the unit. This PCB is the control center of the electrical signals and operations of the HVAC equipment as well as the controller of the performance of the equipment. Working at 24V, the PCB manages the components including motors, sensors and switches to achieve the required environmental conditions. From 32°F to 122°F, it operates stably in different climates, which means that it will work efficiently both in heating and cooling systems.
