Fan Proving Switch 125 VA @ 24 VAC 300 VA Up to 277 VAC
To satisfy national mechanical codes for oil and gas installations, Draft Inducers must be properly interlocked with burner circuits. The PS1505 Fan Proving Switch monitors pressure within the Inducer housing to verify Inducer operation. Used in conjunction with the UC1 Universal Control, it assures compliance with codes and simplifies electrical interlock with all 24/115 VAC burner circuits. The PS1505 is not compatible with millivolt gas valves.
