Description
The MARS 33215 Sequencer is a high-quality multi-position time delay relay that serves HVAC systems in electric furnaces, heat pumps, and air handlers. Through its sequencer design, this controls both heating element activation and deactivation while also preventing electrical overload to ensure operational efficiency. The sequencer functions through a bi-metallic strip that changes temperature to activate and deactivate circuits following a specific order for staged heating element activation. The sequencer system protects electrical components by controlling inrush current flow which leads to longer system life. The system delivers three main advantages through its energy-efficient operation its ability to protect components from damage and its safety feature that blocks sudden power surges.
