Function
The ZVR series is a multi-zone 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 3, 4,
5 or 6 zones, depending on model selected. 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
ZVR series is a perfect match with Caleffi’s Z-one™
motorized zone valves.
