CAUTION: Voltage Hazard.
Can cause electrical shock or equipment damage. Disconnect power before beginning installation. Wire the entire panel before applying transformer power. Follow these steps for wiring all systems. However, the wiring will vary depending on the 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 the instructions provided with thermostats.
Connect thermostat to zone panel. To connect wire to the panel, strip approximately 1/4 in. of insulation and push the wire into the terminal. To release the 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.
Connect outdoor air temperature sensor as shown. Required for dual fuel systems; optional for other multistage systems.
Connect equipment as shown.
If using any wireless device, connect the ABCD terminals for the wireless interface module.
Connect transformer as shown.
The following diagram is an overall view of wiring for a conventional system as depicted in steps 3–9.
Use the following diagram for wiring a 2-heat/1-cool 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.
Use the following diagram for wiring a 3-heat/2-cool heat pump with electric stage 3 heat.
Use the following diagram for wiring a dual-fuel system with single-stage furnace and single-stage heat pump.
Use the following diagram for wiring a dual-fuel system with two-stage furnace and two-stage heat pump.

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.
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 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. |
