Honeywell R845A1030 switching relay dpst w/ transformer


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.
Switching relay with internal transformer, provides Dpst switching for hot water zone control systems, or spst control of two separate loads.
Provide intermediate switching of a line voltage device form a low voltage controller.
DPST; one pole line voltage, the other line or low voltage
