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 onlyhoneywell hz221 truezone Installation
  2. Separate the zone panel cover from the base, and use the base as a template to drill mounting holes. 2 Attach the base to the wall, stud, roof truss, or duct with appropriate screws (not included).honeywell hz221 truezone Installation
  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 hz221 truezone Installation
  4. Install dampers using instructions provided with dampers. Connect dampers to zone panel. NOTE: Multiple dampers can be wired in parallel.honeywell hz221 truezone Installation
  5. Connect DATS as shown.honeywell hz221 truezone Installation
  6. Connect equipment as shown. The DS/BK terminal is used with a variable-speed fan. Connect to the DS, BK, or ODD terminal on the furnace equipment. When only one zone calls for heat, cool, or fan, the DS/BK terminal operates the fan at low speed to reduce airflow.honeywell hz221 truezone Installation
  7. Connect transformer as shown.honeywell hz221 truezone InstallationThe following diagram is an overall view of wiring for a heat pump system as depicted in steps 3–7.

Operation

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

Table 5. LED Operation.

LED

Description

HEAT

Solid 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.

COOL

Solid when in cool. Blinking when 45°F (7°C) DATS low limit mode has been reached.

FAN

Solid when in operation.

PURGE

Solid 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 shorted or open. Will blink for 3 minutes at power-up if DATS is not present.

ZONE 1, 2

Solid green when open or opening. Solid red when closed or closing.

Blinking amber when there is a damper or thermo- stat short circuit (circuit breaker trip).

EM HEAT

Solid when in Em Heat mode.
