TotalZone® Add-A-Zone™(TAZ-4)
Zone Control Panel
INSTALLATION INSTRUCTIONS
APPLICATION
The TAZ-4 is a zone panel used to add zones to the TZ-4. See
Fig. 1. The TZ-4 provides up to four zones. Each TAZ-4 can
add up to four additional zones for a total of 32 zones. The
TAZ-4 is also compatible with the TZ-3, Rev 4.2.2, zone
control panel and with the TAZ-1, TAZ-2 and TAZ-3, Rev 4,
Add-A-Zone panels.

3. Installer must be a trained, experienced service technician.
4. After installation is complete, check out product operation as provided in these instructions.
5. Follow local codes for installation and application.
CAUTION
Voltage Hazard.
Can cause electrical shock or equipment damage.
Disconnect power before beginning installation.
Location
Select a location for the TAZ-4 as close as possible to the
Total Zone panel.
Mounting
Mount the TotalZone Add-A-Zone Panel as close as possible
to the TotalZone Panel. See Fig. 1.
WIRING
CAUTION
Electrical Interference Hazard.
Running cable near line voltage can interfere with
panel operation.
Run cable connecting AZ terminals at least
12 in. from line voltage wiring.

IMPORTANT
Be sure AZ1 and AZ2 wires do not cross and are a
minimum of 12 in. from any line voltage wiring. If not
possible, use shielded cable for AZ1 and AZ2 wires.
NOTE: Only two wires are required to connect the TAZ-4
panels to the main TZ-4 panel. Each TAZ-4 is wired
in a daisy chain or parallel to each other, connecting
the AZ1 and AZ2 terminals between panels.
Connect the AZ1 and AZ2 terminals on both panels using
standard 18-gauge thermostat wire:
1. Connect AZ1 on the TotalZone panel to AZ1 on the
Add-A-Zone panel.
2. Connect AZ2 on the TotalZone panel to AZ2 on the AddA-Zone panel.

3. Connect a 24V, 40 VA transformer to terminals R and C.
R is Hot and C is 24 Vac (Common). See
Fig. 2.
4. If there are five to ten ARD or ZD dampers connected to
the TAZ-4, wire an additional 40 VA transformer to T1
and T2. See Fig. 2.
5. Connect damper and thermostat wiring as shown
in Fig. 2.

SETUP
Each TAZ-4 panel has a set of five DIP switches. When using
a TZ-4 and one TAZ-4, set DIP switches 1, 2, and 4 to off and
switches 3 and 5 to on. Refer to Table 1 for other panel
configurations. Identify the zones that are controlled by the
TAZ-4 panel and set the DIP switches accordingly.
If the TAZ-4 is connected to a TZ-3 zone control panel, set
DIP switches 1, 2, and 4 to off, and switches 3 and 5 to on.
Set the switches on additional TAZ-1, TAZ-2, and TAZ-3, or
TAZ-4 panels to control the zones they are wired to; but be
careful that there is no duplication of zone numbers. See
Table 1.
