Safety First: Normally closed configuration ensures the valve remains sealed during power loss for maximum system protection
Optimized Sanitization: Smooth interior surfaces and a large 5-3/4" bottom hole facilitate rapid cleaning and simplified maintenance routines
causing pressure switch trips and system lockout
Use a multimeter to check for resistance across the terminals
MARS 33266 Relay 321702-401 Safety First: Normally closed configurationThe MARS 33266 is a heavy duty DPST Time Delay Relay engineered for precision timing in residential and commercial HVACR systems. As a veteran grade electric heat sequencer relay, this component is designed to manage high current 240V electrical loads, providing critical protection for compressors and fans by preventing short cycling. By implementing a consistent time delay for HVAC compressors, it mitigates the mechanical strain caused by rapid
