Function
The ZVR series is a multi-zone zone valve and boiler
operating control for 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.
