Taco Comfort Solutions SR503-4 is the Switching Relay - 3 Zone w/Priority.

This switching relay controls 3 circulators in a zoned hydronic heating system, operating the pumps and the boiler from thermostat calls. Priority lets one zone, usually an indirect water heater, take precedence over the space heating zones.

Check the number of zones, the thermostat type and the circulator electrical load before choosing a relay. Wiring terminals are grouped by zone for straightforward installation and troubleshooting.
