MOUNTING
-
Mount the HZ432 TrueZONE panel near the HVAC equipment; locate it on a wall, stud, roof truss, or coldair return.
NOTE: The HZ432 TrueZONE panel can be mounted in any orientation; level it for appearance only. -
Separate 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).
WIRING
CAUTION: Voltage Hazard.
Can cause electrical shock or equipment damage. Disconnect power before
beginning installation.
Wire entire panel before applying transformer power.
Follow these steps for wiring all systems. However, wiring will vary depending on equipment. For conventional systems, 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.
-
Install thermostats using instructions provided with thermostats.
If using wired thermostats, connect thermostat to zone panel. To connect 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.
-
Install dampers using instructions provided with dampers.
Connect dampers to zone panel.
NOTE: Multiple dampers can be wired in parallel.
-
Connect DATS as shown. See high and low limit settings in Table 5 “Advanced Configuration”
-
Connect outdoor air temperature sensor as shown.
Required for dual fuel systems; optional for other multistage systems. If using the C7089R1013 wireless outdoor sensor and THM4000R wireless adapter on 2- to 4-zone systems,
-
Connect equipment as shown here.
-
When a wireless thermostat, Portable Comfort Control, wireless outdoor air temperature sensor, or other RedLINK™ wireless device is used on systems up to four zones, wire the THM4000 Wireless Adapter Module to the ABCD terminals on the zone panel.
For systems with more than 4 zones,
CAUTION: Do not wire the A-B-C-D terminals of the THM5320R or THM5421R Wireless Equipment Interface Module to the A-B-C-D terminals on the HZ432 zone control panel. Doing so will damage the components -
Connect a dedicated transformer as shown

CONFIGURATION
To enter Configuration:
-
Press the Mode button (the Config LED will light up)
-
Use the Back and Next buttons to navigate through the configuration settings. Scroll through the selection choices by using the “Adjust Setting” Left and Right arrow buttons. Pressing Next enters the selected option for that menu item and advances to the next menu.
-
The flow chart below illustrates basic zone panel configuration. For additional configuration, see Advanced Configuration. The label on the inside cover of the HZ432 Zone Panel also contains configuration information.
C7089U1006 WIRED OUTDOOR SENSOR, OR C7089R1013 WIRELESS OUTDOOR SENSOR AND THM4000R1000 WIRELESS ADAPTOR REQUIRED IF DUAL FUEL OPERATION IS SET TO YES.
SET TO “YES” IF WIRELESS (RADIO FREQUENCY) THERMOSTATS AND THM4000R ADAPTOR ARE USED. SET TO “NO” IF THE THM5320R IS USED AS DESCRIBED.
CANNOT USE TAZ-4 ADD-A-ZONE WITH THE HZ432 IF RF ENABLED IS SET TO “YES”.
SYSTEM IS LIMITED TO 4 ZONES WHEN THM4000
WIRELESS ADAPTER IS USED.
vSHOWN IF COMPRESSR STAGES, HEAT STAGES, OR DFUEL HT STAGES IS SET TO 2, OR AUX HT ENABLED IS SET TO “YES”
SHOWN ON NON DUAL FUEL HEAT-PUMPS IF COMPRESSR STAGES IS SET TO 2 AND AUX HT ENABLED IS SET TO “YES”, OR ON CONVENTIONAL APPLICATIONS IF HEAT STAGES IS SET TO 3.
CONNECT WIRELESS DEVICES
If connecting wireless devices, press the Mode button until the Wireless LED lights up. The TrueZONE must be configured for wireless devices to select Wireless mode.
- Press Next to add devices.
- While the display alternates the Press Connect and
- Exit screens, push the Connect button(s) on the wireless device(s).
- -ORFollow the instructions that came with the wireless device(s).
- Press Next to exit.
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).
If using a THM4000R wireless adaptor, a maximum of 4 zones may be used. For
applications using wireless thermostats and requiring more than 4 zones, do
not use a THM4000R. Instead, wire a separate EIM (Equipment
Interface Module) to the thermostat terminals of each zone on the zone panel.
Then link each wireless thermostat to the corresponding EIM. Configure the
HZ432 for RF Enabled = NO. The EIM used with RedLINK VisionPRO and Prestige
models is THM5421R1021. The EIM used with RedLINK FocusPRO models is
THM5320R1000.
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.
ADVANCED CONFIGURATION
Use the Adjust Setting, Next, and Back buttons to configure the zone panel. See the Configuration section on page 10 for instructions on using these buttons. Options/information displayed will vary by system type, control type, number of zones, and other settings.

OPERATION
Much of this information, as well as configuration information, is listed on the label on the inside of the HZ432 cover. For users who prefer French or Spanish labels, they are provided in form 69-2198FS. Cut them out and attach them to the inside of the HZ432 cover.
Table 6. LED Operation.
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 sen- sor 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, 3, 4| 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, causing
that zone’s breaker to trip.
CHECKOUT
To enter Checkout, with the zone panel cover off, press the Mode button until the Check out LED lights up. Use the 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
thermostat terminals are actually energized on each zone.
