MOUNTING

1. Mount the HZ322 TrueZONE panel near the HVAC equipment; locate it on a wall, stud, roof truss, or cold air return.NOTE: The HZ322 TrueZONE panel can be mounted in any orientation; level it for appearance only.
2. 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 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.
3. Install thermostats using instructions provided with thermostats.Connect thermostat to zone panel. To connect the wire to the panel, strip approximately 1/4 in. of insulation and push wire into the terminal. To release wire, press the button on to-p of the terminal. In retrofit applications, trim end of wire if not  straight.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.
4. Install dampers using instructions provided with dampers. Connect dampers to zone panel.NOTE: Multiple dampers can be wired in parallel.WIRING
5. Connect DATS as shown. See high and low limit settings in Table 5 “Advanced Configuration” on page 8.For the placement of DATS in the supply duct and troubleshooting assistance with the DATS, see the Discharge Air  Temperature Installation InstructionsForm Number 69-1521.
6. Connect the equipment as shown here and on pages 5 and 6.For oil heat with a separate transformer for cooling, remove this jumper. For other systems leave the jumper in place and wire to the HVAC R terminal with 18 gauge solid wire.

   The DS/BK terminal is used with a variable-speed fan. If the HVAC equipment has a DS, BK, ODD, or DHUM terminal, wire that terminal to the HZ322 DS/BK terminal. When 2 or 3 zones are calling for cooling this terminal will be energized which will run the blower fan at the normal speed. When only 1 zone is calling for cooling the fan runs at a reduced speed which will require less air to be bypassed. Refer to HVAC equipment manufacturer instructions.

7. When a wireless thermostat, Portable Comfort Control, wireless outdoor air temperature sensor, or other RedLINK™  wireless device is used, wire the THM4000 Wireless Adapter Module to the ABCD terminals on the zone panel.

   CAUTION: Only the THM4000R can be wired to the A-B-C-D terminals on the HZ322. Do not wire the A-B-C-D  terminals of the THM5320R or THM5421R Equipment Interface Module to the A-B-C-D terminals on the HZ322 zone control panel. Doing so will damage the components.

8. Connect a dedicated transformer as shown.

CONVENTIONAL

The following diagram is an overall view of wiring for a conventional system as depicted in steps 3–8.

Fig. 11. Zone panel wiring—conventional.

HEAT PUMP

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.

Fig. 12. Zone panel wiring—heat pump with electric auxiliary heat.

1. ADD A JUMPER FROM W1/E TO W2 AT EACH ZONE.
2. FOR THERMOSTATS WITH SEPARATE 0 AND B TERMINALS, ATTACH 0 FOR COOL CHANGEOVER OR ATTACH B FOR HEAT CHANGEOVER.
3. IF HVAC EQUIPMENT USES THE SAME SOURCE OF HEAT FOR AUXILIARY AND EMERGENCY HEAT, JUMPER W1/E AND W2.
4. ABCD TERMINALS FOR THE THM4000R WIRELESS ADAPTOR ONLY. NEVER WIRE A THM532OR OR THM5421R EIM TO THESE TERMINALS.

OPERATION

The HZ322 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 HZ322 cover. For users who prefer French or Spanish labels, they are provided in form 69-2199FS. Cut them out and attach them to the inside of the  HZ322 cover.

Table 7. LED Operation.

LED	Description
HEAT 1	Solid when in heat stage 1. Blinking when DATS high limit mode has been reached.
HEAT 2	Solid when in heat stage 2. Blinking when stage 2 is 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 the 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 the 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.
ZONE 1, 2, 3	Solid green when open or opening. Solid red when closed or closing. Blinking amber when the damper VA exceeds the specified zone VA or there is a damper or thermostat short circuit (circuit breaker trip).

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 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 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.
