123
Boiler connections:
XX = Dry contact rated up to 120 VAC, 2 Amps,
which is typically connected to TT on boiler control,
closes when any zone calls including priority.
ZONE 1 E/S = Dry contact rated up to 120 VAC, 2 Amps, will close with
any call to ZONE 1. Zone 1 can be enabled as a priority zone, typically
used for heating domestic hot water. The ZONE 1 E/S can be used to
close a DHW contact on boiler controls equipped with these features.
AUX = Dry contact, rated up to 120 VAC, 2 Amps, close when any zone
calls and can be used as signal to a variable speed self regulated pump
or other controls.
The ZVR series of controls is programmed by the dip switches which can
be positioned for the following operations.
Master / Slave: allows for
unlimited expansion to additional
ZVR or ZSR relays.
Pump Exercise ON / OFF:
When exercise mode is ON, each
circulator is switched on for 30
seconds following 72 hours of
inactivity.
Priority ON / OFF: When priority
switch is ON, upon demand, Zone 1 will operate as priority and all other
zones are temporarily switched off (with 1 hour time-out). When priority is
OFF, any zones that were active when Zone 1 was switched on will remain
on.
AUX ON / OFF Durning Priority Demand: When AUX switch is ON,
the AUX dry contacts will close during a priority demand. When switch is
OFF, the AUX dry contacts will remain open during a priority demand.

The Caleffi Z-one™ multi-zone valve relay comes with an automatic
resettable fuse and requires no maintenance. If control fails or is damaged,
replace control with functional one.

be a direct short on the 24 VAC supply.
WARNING: When connecting 2 or more Z-one controls,
all controls must be powered by the same 120 VAC
circuit.
