R845 Honeywell Switching Relay Wiring Diagram R845. Switching Relay provides DPST switching for hydronic zone controlled heating systems or SPST control of two separate loads. One load must be line voltage; the other may be either line or low voltage.
R845 Honeywell Switching Relay Wiring Diagram I'm installing a new Burnham Oil fired bolier that came with a Honeywell L7248C Controller. The house has an existing Honeywell R845 switching relay to controll the second zone in the house. The wiring digram shows the leads coming from the #1 and #4 terminals on the R845 going to the ZC and ZR terminals on the L7248C.
