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.

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.

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.
