Caleffi ZVR103 - Z-one™ Relay (three zone)

MULTI-ZONE VALVE CONTROL

The ZVR103 is a multi-zone zone valve and boiler operating control for multiple zone hydronic heating systems. The ZVR103 interfaces with low voltage thermostats, or any other low voltage controllers having a switching action. The ZVR103 controls up to 3 zones. In addition, a system pump, secondary pump and a priority (DHW) pump can also be controlled. LED indicators provide functional status and easy system troubleshooting. The ZVR106 is a perfect match with Caleffi’s Z-one™ motorized zone valves.
