MOUNTING
Mount the HZ432 TrueZONE panel near the HVAC
equipment; locate it on a wall, stud, roof truss, or cold-
air return.
NOTE: The HZ432 TrueZONE panel can be mounted in
any orientation; level it for appearance only.
1
2Separate the zone panel cover from the base, and use the base as a template to drill mounting holes.
Attach the base to the wall, stud, roof truss, or duct with appropriate screws (not included).
Use two screws for attaching to a stud or roof truss, or
four screws for duct or drywall/plaster installations.

WIRING
Follow these steps for wiring all systems. However, wiring will vary depending on equipment. For conventional sys-
tems, see page 5. For heat pump systems, see pages 6 and 7. For dual fuel systems, see pages 8 and 9.
Wiring must comply with applicable codes, ordinances, and regulations. Use the following wiring diagrams to wire
the zone panel to the thermostats and dampers.
The HZ432 offers many innovations for wire management and organization: wires can be run
behind the panel, through wire channels on its sides, and must be attached to a wiring anchor
with a cable tie.
M24743
Install thermostats using instructions provided with thermostats.
If using wired thermostats, connect thermostat to zone panel. To con-
nect wire to the panel, strip approximately 1/4 in. of insulation and
push wire into terminal. To release wire, press the button on top of
the terminal.
3
Install dampers using instructions provided with dampers.
Connect dampers to zone panel.
NOTE: Multiple dampers can be wired in parallel.

The DS/BK terminal is used with a variable-speed fan.
If the HVAC equipment has DS, BK, ODD, or DHUM ter-
minals, wire that terminal to the DS/BK terminal. When
greater than 25% of zones are calling for cooling, this
terminal will be energized and the fan will operate at nor-
mal speed. When 1 zone or fewer than 25% of zones are
calling for cooling, the terminal will be de-energized and
the fan will run at a reduced rate, which will reduce the
amount of air that needs to be bypassed. This reduces
blower speed on most variable speed blowers. Refer to
HVAC equipment manufacturer instructions.
For oil heat with a separate transformer for cooling,
remove this jumper.
For other systems, leave jumper in place and wire to
HVAC R terminal with 18 gauge solid copper wire.
Connect DATS as shown.

If using more than 4 zones, use the TAZ-4 Add-A-ZoneTM
Control Panel. Follow instructions with the TAZ-4 for
installation (form 69-1366).
Note: If using wireless thermostats, a maximum of 4
zones may be configured when using the THM4000 wire-
less adpater.
For applications requiring more than 4 zones using wire-
less thermostats, wire a THM5320R Wireless Equipment
Interface Module to the thermostat terminals of each
zone on the zone panel, and configure the panel for wired
thermostats. Note that no THM4000R Wireless Adapter is
used in this more than 4 zone setup.
CAUTION
Do not wire the A-B-C-D terminals of the THM5320R to
the A-B-C-D terminals of the HZ432 zone control panel.
Doing so will damage the components.

LED Description
HEAT 1 Solid when in heat stage 1. Blinking when DATS high limit mode has been
reached.
HEAT 2, 3 Solid when in heat stage 2, 3. Blinking when stage 2, 3 locked out due to
DATS or OT.
COOL 1 Solid when in cool stage 1. Blinking when DATS low limit mode has been
reached.
COOL 2 Solid when in cool stage 2. Blinking when stage 2 locked out due to DATS.
PURGE Solid when in purge (at power-up and after a call for heat or cool).
Blinking when the DATS sensor has failed, or the wires are shorted or
open. Will blink for 3 minutes at power-up if DATS is not present.
FAN Solid with a call for fan.
EM HEAT Solid when in emergency heat mode. This light does not indicate a call for
heat. Emergency heat will only run when both HEAT and EM HEAT are lit.
ZONE 1, 2,

Solid green when open or opening. Solid red when closed or closing.
Blinking amber when the VA draw of the dampers exceeds the specified
VA, or if there is a short circuit on the damper or thermostat wiring, caus-
ing that zone's breaker to trip.

Adjust Setting and Next buttons to work through the checkout menu as listed below. See the Configuration section on
page 10 for instructions on using these buttons.
Steps 3–10 cycle through heating and cooling stages and open and close dampers to verify proper operation of the
equipment and dampers. These steps energize the equipment and damper terminals.
Steps 11–14 verify thermostat operation and correct wiring. This is done by making the thermostats call for heat or
cool and viewing the active wires as displayed on the LCD screen. This is a useful way to troubleshoot which ther-
mostat terminals are actually energized on each zone.
