The ZSR series is multi-zone pump and boiler operating control for multiple
zone hydronic heating systems. The ZSR series interfaces with low voltage
thermostats, or any other low voltage controllers having a switching action.
The ZSR series controls up to 3, 4, 5 or 6 heating circulator pumps,
depending on model selected, a primary pump and has LED indicators to
provide functional status and easy system troubleshooting. In addition, a
primary pump system circulator is switched on whenever any zone calls
for heat.

VALVE ZONE CONTROLS
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.
