This premium 2-pole electric heat sequencer is an essential control component for residential and commercial HVAC systems, including electric furnaces and heat pump air handlers. Designed to operate on a 24V control circuit, this relay facilitates the staged activation of heating elements, preventing electrical overloads and power surges that can occur when multiple elements energize simultaneously. By sequencing the timing of the heating stages and the blower motor, it ensures a smooth transition of airflow and heat output, enhancing the efficiency and longevity of your heating system. This heavy-duty sequencer is the ideal solution for repairing furnaces that fail to cycle correctly or blowers that do not engage during the heating cycle.
