Description
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.
