Product Overview

Primary pump output:
Primary pump runs when any zone pump
runs. Its status during priority (on\off) can be
programmed using the jumper pins.
L = Line (hot leg) of 120 VAC to power the
pump
N = Neutral leg of 120 VAC to power the pump
Status During Priority ON / OFF: If priority is enabled and the jumper
is placed on the ON pins, the primary pump will continue to operate
during ZONE 1 demand. When jumper is placed on OFF pins, the primary
pump will be OFF during ZONE 1 demand.
Zone pump outputs:
Zone pumps run when
corresponding thermostat
initiates a demand.
GROUND = Connect the ground from the pump to the ground terminal.
PRIORITY PUMP = Runs when zone #1 calls. Can be programmed to
be the priority zone. L = Line (hot leg) of 120 VAC to power the pump,
N = Neutral leg of 120 VAC to power the pump. Remote Enable allows
for input of 24-120 VAC from a boiler to allow the zone pumps to
operate. When power is removed from Remote Enable, zone pumps
will not be allowed to operate. This is useful during warm weather
shut down to stop zone pumps from running or if your boiler controls
are used to handle priority (DHW) demand and need the zone pumps
to be off during the priority demand. Even with power removed from
Remote Enable, the ZSR board stays powered to supply power to the
thermostats.
Input Power:
L = Line (hot leg) of 120 VAC supply
N = Neutral of 120 VAC
= Ground
Note: when connecting 2 or more Z-one
controls, all controls must be powered by the same 120 VAC circuit.
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.

Maintenance and Repair: The Caleffi Z-one™ multi-zone pump control
comes with two spare fuses. If control fails or is damaged, replace control
with functional one.
Communication connections:
Connect terminals to matching terminal of slave
boards D to D, P to P, Ground to Ground. Use 18
gauge thermostat wire and it should be shielded if
located in close proximity to high voltage wiring.

WARNING: NEVER CONNECT R & C DIRECTLY, this will 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.
The ZSR series of control is
programmed by positioning five
dip switches for the following
operations.
Master / Slave: allows for
unlimited expansion to additional
ZVR or ZSR relays. Only one
Master.
Priority ON / OFF: When priority switch is ON, upon demand to TSTAT
1 , 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.
Remote Enable ON / OFF: When remote enable mode is ON, the board
will hold off all zones waiting for an external 24 - 120 VAC voltage from
the boiler.
Exercise ON / OFF: When exercise mode is ON, each circulator is
switched on for 30 seconds following 72 hours of inactivity.
Post Purge Zone #1 ON / OFF: When post purge is ON, Zone 1 pump
continues operating for 2 minutes after the priority zone is switched OFF.
