The ZVR series is a multi-zone valve relay and boiler operating control
ior multiple zone hydronic heating or cooling 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.
