A physical "click" upon pressing indicates the safety circuit was opened due to an over-temperature event

This HVACR control is typically utilized in systems where DPST single control is required to bridge low-voltage thermostat signals with line-voltage circulator or burner demands

While the DFS2-DM20 is capable of monitoring temperatures down to 34°F

which are primary causes of mechanical failure in low-ambient conditions

Reduced Mechanical Wear: Proper sensing prevents rapid cycling of burners and pumps
