MOUNTING
-
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.
-
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).
-
Install thermostats using instructions provided with 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. 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. -
Install dampers using instructions provided with dampers. Connect dampers to zone panel.
NOTE: Multiple dampers can be wired in parallel.
-
Connect DATS as shown. For the placement of DATS in supply duct and troubleshooting assistance with the DATS, see the Discharge Air Temperature Installation Instructions Form Number 69-1521.
-
Connect equipment as shown here and on page 5 and 6
-
When a wireless thermostat, Portable Comfort Control, wire- less 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.
-
Connect a dedicated transformer as shown.
ADVANCED CONFIGURATION
Use the Adjust Setting, Next, and Back buttons to configure the zone panel. See the Configuration section on page 7 for instructions on using these buttons.
