Z-one 4 Zone valve control Relay

The ZVR series is a multi-zone valve relay and boiler operating control for multiple-zone hydronic heating systems. The ZVR series interfaces with low-voltage thermostats or any other low-voltage controllers having a switching action. The ZVR series controls up to 3, 4, 5 or 6 zones, depending on the model selected. In addition, a system circulator pump and secondary pump is turned on whenever any zone calls for heat. LED indicators provide functional status and easy system troubleshooting. The ZVR series is a perfect match with Caleffi’s Z-one™ motorized zone valves.
