Caution
3.2 Electrical installation
CAUTION
Class 2 wiring must be segregated
from the wiring of Class 1 circuits.
When Class 2 wiring is routed with
Class 1 wiring, the Class 2 wiring
insulation must be rated for the
minimum voltage of the Class 1
wiring. Segregation is not required if
all circuits are wired as Class 1,
electric light or power circuits.
3.2.1 Wiring connections
• All electrical connections must be made
using copper wire only.
• 12-16 AWG wire is recommended for 120
VAC connections.
• 12-22 AWG wire for thermostat connections.
• 12-22 AWG wire for 24 VAC connections.
• Use approved UL conduit fittings.
You can find additional wiring schematics,
specs, and troubleshooting help online at

Fig. 3 UPZCV multi-zone valve board expansion
See fig. 3.
• You can only use the MASTER controller
with PRIORITY.
• When priority calls, the MASTER board will
produce 5 VDC between terminals B and C.
This tells the SLAVE board to turn off any
zones that are calling for heat. This also will
close the contacts XX PRIORITY.
• When there is a demand for heat, the SLAVE
board will produce 5 VDC between terminals
A and C. This tells the MASTER board to
activate any boiler or secondary pumps and
close the contacts XX MAIN.
• You can connect the pump and valve boards.
• When the SLAVE board calls for heat, the
secondary pump will be powered. If a boiler
pump and secondary pump are to be used,
connect them to the same terminals.
• You can use the low voltage wire to connect
the ABC terminals.
• Connect the 120 VAC power supply to each
board.
CAUTION
Connect the L and N terminals the
same way on each board. If switched,
a differential of 240 VAC can occur
resulting in damage to the equipment.

5. Product introduction
5.1 Features and benefits
• Compatible with 2-, 3-, and 4-wire low
voltage controllers or thermostats.
• Wiring ease with 120 VAC, ground and low
voltage screw terminal inputs.
• Low voltage end-switch output terminals for
the zone valves.
• Replaceable 40 VA transformer (snap-fit) for
the zone valve controllers only.
• Zone priority with selectable time-out
feature.
• Pump exercise feature, selectable 72 hours
or 14 days.
– The pumps will be turned on for 30
seconds every 72 hours or 14 days in
order to prevent pumps from seizing up.
This feature will only work if there is a
jumper wire connecting the ZR ZC
terminals on the pump controller.
• Boiler demand terminals.
– The two terminals, labeled MAIN XX, are
wired to the boiler. When the contacts
close, the boiler starts and will come up to
a preset temperature for hydronic heating.
• DHW terminal.
– The two terminals, labeled PRIORITY XX,
are wired to the boiler. When the contacts
close, the boiler starts and will come up to
a preset temperature for domestic hot
water heating.
• Front facing LED indicator lights on the
cover.
• Side-mounted terminal connections for ease
of wiring and installation.
