TRADELINE Installation Instructions
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.
| Features
