this component provides enhanced responsiveness and tighter temperature control compared to standard non-assisted switches

When you're troubleshooting a furnace that won't initiate the ignition sequence

Whether you are working with R-410A systems or standard vacuum applications

MARS 33246 Sequencer The robust construction of theThe MARS 33246 Sequencer is a field proven DPST electric heat sequencer engineered for multi stage staging in electric furnaces, heat pumps, and air handlers. This 2 switch thermal time delay relay utilizes a solid state PTC (Positive Temperature Coefficient) heater to provide reliable, voltage compensated timing, ensuring consistent performance even during line voltage fluctuations. With a 24V control circuit, it manages the sequential activation of
