MOUNTING
Mount the HZ432 TrueZONE panel near the HVAC
equipment; locate it on a wall, stud, roof truss, or cold-
1
air return.
NOTE: The HZ432 TrueZONE panel can be mounted in
any orientation; level it for appearance only.
Please refer to TrueZONE Panel Frequently Asked
Questions form 50-9694 for operating details.
Fig. 2
2
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).
Use two screws for attaching to a stud or roof truss, or
four screws for duct or drywall/plaster installations.

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, refer to this page. 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.
3
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.
Fig. 5

Fig. 4
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.
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.
Connect the DS, BK, ODD, or DHUM terminal on the
HVAC equipment to this terminal. When 1 zone is calling
(or 25% on systems with more than 4 zones) this terminal will be de-energized of 24 VAC. This reduces blower
speed on most variable speed blowers.

LED Description
HEAT 1 Solid when in heat stage 1. Blinking when DATS high 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.

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.
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.
