Jumper set up
The jumpers on the ZVR series can be positioned for the
following operations.
Priority ON / Priority OFF: When priority jumper is ON, upon
demand, zone 1 will operate as priority and all other zones are
R W C
temporarily switched off (with 1 hour time-out). When priority
POWER IN
mode is OFF, any zones that were active when zone 1 was
T T COM
N
switched on will remain on.
T-STAT 3
Status During Priority ON / Status During Priority OFF: When
status jumper is ON, the system pump will continue to operate
during priority.
W C R W
Master / Slave: allows for unlimited expansion to additional ZVR

relays.

When a zone has a demand from a thermostat (T T or R W) the control will send 24 VAC to the
corresponding zone valve. When the zone valve end switch closes, the primary pump will switch
on and the (X X) dry contacts will close to signal the boiler of a heating demand. Zone 1 can be
used for priority (either a priority pump or valve). When the priority jumper is ON, a demand from
ON OFF
T-Stat1 will activate 24VAC to valve 1 and the priority pump will switch on after the end switch

closes (requires a jumper in the end switch terminals if a valve is not used). The DHW (ZR/ZC)
TRANSFORMER
dry contact will also close. Depending upon "Status During Priority" jumper, the system pump will

Large screw terminals connections makes wiring easy with three pump screw terminal connections.
POWER IN
Pump terminals connection have 120 VAC outputs for simplified pump connections. Zone valve

connections can be 2, 3 or 4 wire.
Z-oneLink unlimited expansion allows adding addition ZVR
series relay controls to a Master ZVR. Communication is
accomplished by connecting three wires (bell or thermostat
wire) to the communication terminals located in the upper
R W C
right hand corner. The jumper is positioned to Master / Slave
position. A demand for heat from any zone will fire the boiler

and start the pump.
