Mount the HZ432 TrueZONE panel near the HVAC equipment; locate it on a wall, stud, roof truss, or cold-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.
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).
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).
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.
WIRING
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.
HEAT PUMP
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.
DUAL FUEL
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.
