The Honeywell R845A1030 Switching Relay provides DPST switching for hydronic zone controlled heating systems or SPST control of two seperate loads. One load must be line voltage; the other may be either line or low voltage. The R845A may be directly controlled by any 2-wire series 80 thermostat, such as the T86A Round Thermostat or T852A Electric Clock Thermostat. Integral transformer provides low voltage power for control circuit.
