HZ432 TrueZONE

APPLICATION

The HZ432 TrueZONE® panel controls:

• Single-stage, multi-stage, conventional, or heat pump heat/cool HVAC equipment up to 3 stages of heat and 2
stages of cool;

• Dual-fuel systems with up to 2 heat pump stages and 2 fossil fuel stages;

• 2, 3, or 4 zones and is expandable to 32 zones using wired thermostats with the TotalZone® Add-A-Zone™

panel;

• 2, 3, or 4 zones with wireless thermostats when used with the wireless adaptor.

Please refer to TrueZONE Panel Frequently Asked Questions form 50-9694 for operating details, or see

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.

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.

If the HVAC equipment has DS, BK, ODD, or DHUM ter­minals, 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 nor­mal 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

HVAC equipment manufacturer instructions.

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

The HZ432 TrueZONE panel contains an LED display that communicates system and
zone status. The LEDs indicate the following information.

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.

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.
