INSTALLATION

  1. Mount the HZ221 TrueZONE panel near the HVAC equipment; locate it on a wall, stud, roof truss, or cold-air return.
    NOTE: The HZ221 TrueZONE panel can be mounted in any orientation; level it for appearance only.
    Honeywell TrueZONE HZ221 Zone Panel Professional fig2
  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).
    Honeywell TrueZONE HZ221 Zone Panel Professional fig3Use two screws for attaching to a stud or roof truss, or four screws for duct or drywall/plaster installations. Wiring must comply with applicable codes, ordinances, and regulations.
    CAUTION: Voltage Hazard.
    Can cause electrical shock or equipment damage. Disconnect power before beginning installation. Wire entire panel before applying transformer power.
  3. 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.
    If the thermostat has separate E and Aux terminals, install a jumper between the two terminals.
    Honeywell TrueZONE HZ221 Zone Panel Professional fig4Note: Thermostat must be configured for changeover in cool mode. If heat pump uses changeover in heat mode, wire the changeover to B on equipment terminals.Honeywell TrueZONE HZ221 Zone Panel Professional fig5Wires can be run behind the panel, through wire channels on the panel’s 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.
  5. Connect DATS as shown.Honeywell TrueZONE HZ221 Zone Panel Professional fig6
  6. Connect equipment as shown.

OPERATION

The HZ221 TrueZONE panel contains an LED display that communicates system and zone status. The LEDs indi-cate the following information.

Table 5. LED Operation.

LEDDescription
HEATSolid when in heat.Blinking when DATS temperature exceeds 120°F (49°C) and calling for heat pump only.Blinking when DATS temperature exceeds 160°F(71°C) and calling for heat pump and auxiliary heat. At 150°F (66°C), auxiliary heat is disabled.
COOLSolid when in cool. Blinking when 45°F (7°C) DATS low limit mode has been reached.
FANSolid when in operation.
PURGESolid when in purge (lasts 2 minutes at power-up and after a call for heat or cool). Blinking when the DATS sensor has failed, or the wires are short- ed or open. Will blink for 3 minutes at power-up if DATS is not present.
ZONE 1, 2Solid green when open or opening. Solid red when closed or closing.Blinking amber when there is a damper or ther- mostat short circuit (circuit breaker trip).
EM HEATSolid when in Em Heat mode.

Much of this information is also listed on the label on the inside of the HZ221 cover.

Honeywell TrueZONE HZ221 Zone Panel Professional fig12

When the zone panel cover is off, the EMERGENCY HEAT/PURGE OVERRIDE but-ton is visible.
When the panel is in Purge (at startup or after a call for heat/cool), pressing this button stops the Purge, which saves time during installation or troubleshooting.
All other times, pressing the button puts the zone panel into Em Heat mode so that all calls for heat are handled by the auxiliary heat.
