TZ-4 TOTALZONE® ZONE CONTROL PANEL
68-0259-1 4
INSTALLATION
Mounting
CAUTION
Equipment Damage Hazard.
Do not mount TZ-4 inside HVAC equipment
Mount only on wall or on cold air return.
Identifying DIP Switches
This panel has two banks of DIP switches, DIP switch 4 (S4)
and DIP switch 5 (S5), see Fig 15. Each bank has eight
individual switches that are identified by two numbers; the first
number is the bank number (4 or 5) and the second number
identifies the individual switch. For example, DIP 5-1 is bank
5, switch 1.
1. Mount the thermostats in each zone of the living space
using the installation instructions provided with each
thermostat.
2. Mount the dampers in the ductwork using the installa-
tion instructions provided with each damper.
3. Mount the TZ-4 zone panel near the HVAC equipment;
(on a wall or on the cold-air return). See Fig. 2.
4. Level the TZ-4 for appearance only.
Wiring
CAUTION
Voltage Hazard.
Can cause electrical shock or equipment damage.
Disconnect power before continuing installation.
Wiring must comply with applicable codes, ordinances, and
regulations.
1. Connect thermostats as shown in Fig. 3-6.
2. Connect dampers as shown in Fig. 7-10.
3. Connect C7735A Discharge Air Temperature Sensor
(not supplied) to the DATS terminals. The wires are not
polarized. See Fig. 13.
4. Connect Add-A-Zone panels (if used) to the AZ1 and
AZ2 terminals.
5. Connect the HVAC equipment to the EQUIP terminals
on the panel. See Fig. 15-21.
6. Connect a 40 VA, 24 volt transformer to R (hot) and C
(common). This must be a dedicated transformer and
each TAZ-4 board also requires a transformer. See Fig.
12.
7. The auxiliary 40 VA 24-volt transformer can be con-
nected to T1 and T2 if additional power for dampers is
required. This second transformer is not required; how-
ever, total power consumption of panel and damper is
limited to 40VA without it.
