ZMS) wiring.
Add-A-Zone Panel
Wire the Add-A-Zone (TAZ) Panel to the TotalZone (TZ-3)
Panel as shown in Fig. 13. Up to nine TAZ Panels can be
wired to one TZ-3 panel. See Fig. 13.
Use 18-gauge thermostat wire for runs up to a maximum of
500 feet. Keep these wires at least 12 in. from line voltage
wiring and equipment; otherwise, use shielded cable wiring.
IMPORTANT:
When multiple panels are used, it is important that
the transformers be in-phase. Check the phasing by
measuring for 24V across the TR2 transformer termi-
nals on each panel. There should be 0 Vac. If not,
reverse the TR1and TR2 transformer wires on one of
the panels and recheck.

Conventional Equipment
Wire the heating and cooling equipment to the equipment
terminals on the TZ-3 Panel as shown in Fig. 14.
Electric Furnaces: Set DIP switch 8 to On to energize the fan
with a call for heat.
Hydro-Air: Wire the zone valve or circulator relay to the W1
equipment terminal. (If the circulator relay has powered
terminals, use an isolation relay.) Set DIP switch 8 to On to
energize the fan with a call for heat.
Oil Heat: Wire an isolation relay on the W equipment wire to
isolate the oil primary from the panel.
