Description
The Supco Q109 Sequencer is an electrical timing and switching component that stages heating elements and blower operation in electric heating equipment through controlled circuit activation. It operates using an internal temperature-responsive mechanism that opens and closes electrical contacts in a timed sequence as the heating element warms and cool. Used into electric furnaces, air handlers, heat pump auxiliary heating sections, and HVAC systems, it connects with low-voltage and line circuits for coordinated equipment operation. Its operation within the heating assembly includes managing staged heater activation and reducing.
