- The ZVR series is a zone valve 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 6 zone valves, depending on model selected. In addition, a system pump and secondary pump is turned on whenever any zone calls for heat. A DHW primary pump can also be operated. LED indicators provide functional status and easy system troubleshooting.
