Identified as a fan and electric heat control board with variable speed capability in HVAC systems, it controls the sequencing of components to ensure correct operation. It works by receiving input from sensors and switches, then directing signals to the blower and heating elements for synchronized response. Located within control compartments, it interfaces with wiring circuits to maintain communication. It stabilizes system operation, supports efficient heating control, and reduces irregular performance during use.
