Tjernlund PS1505 Fan Proving Safety Interlock Switch for Draft Inducer Fans

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.

Doc fetch goes through Layer's Aerospike pull-through cache; cache hit served the row without touching turbopuffer. The similar query asks Layer for nearest neighbors of the stored product vector — queries don't go through the doc cache, so no cache header is set.
