NOTE: The HZ322 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.

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 page 5. For heat pump systems, see page 6.

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.

In retrofit applications, trim end of wire if not straight.

Fig. 5

4

Fig. 4

The HZ322 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.

Use the following diagram for wiring a heat pump with electric auxiliary heat.

NOTE: You can use a conventional thermostat for a heat pump system; however, em heat can only be controlled by
heat pump thermostats. The diagram below shows a heat pump thermostat used with a heat pump system.

Adjust Setting and Next buttons to work through the checkout menu as listed below. See the Configuration section on
page 7 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.
