Once installed and wired correctly, the Taco ZVC403 operates automatically in conjunction with your thermostats and zone valves.
- When a thermostat calls for heat/cool in a specific zone, the ZVC403 energizes the corresponding zone valve.
- Upon the zone valve opening, the ZVC403 signals the boiler/pump to activate, circulating heating/cooling fluid to that zone.
- The external indicator lights on the unit provide real-time status of each zone and the system's overall operation.
- The switchable priority feature allows you to designate a specific zone (e.g., domestic hot water) to take precedence over others when multiple zones call for heat simultaneously. Consult the detailed wiring diagram for priority setup.
