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
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.
