RECOMMENDED THERMOSTATS, DAMPERS, AND ACCESSORIES
The following are suggested thermostats, dampers, and accessories for use with the TrueZONE panel.

Table 1. Recommended Thermostats.

System	Non-Programmable	Programmable
Heat Pump	TH3210D, TH5220D, TH5320U	TH4210D, TH6220D, TH8220U, TH8321U, YTH9421C

Note: These thermostat models all have different fourdigit suffixes. All versions of the model numbers listed above will work with the applications they’re listed for.

Table 2. Recommended Dampers.

Type	Honeywell Damper	Round	Rectangular
Zone	Spring-open/ power-closed	ARD	ZD
Zone	Power-open/ power-closed	MARD/ RRD	For recommended dampers call the Honeywell Zoning Hotline at 1-800-828-8367.
Bypass	Static pres- sure regulat- ing damper	SPRD	SPRD

Table 3. Maximum Dampers

Ambient Temp.	Maximum Damper VA per Zone
100°F (38°C)	28.8
160°F (71°C)	16.8

Use an SDCR (Slave Damper Control Relay) for additional dampers.
Maximum dampers per panel is limited by transformer size.
Ensure transformer is large enough to power the panel (6.25 VA) and dampers.

Included in HZ221K kit.

Installation

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.
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).
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.
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.
Install dampers using instructions provided with dampers. Connect dampers to zone panel.
NOTE: Multiple dampers can be wired in parallel.
Connect DATS as shown.

Wiring

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.

Connect transformer as shown.

The 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.

When the zone panel cover is off, the EMERGENCY HEAT/PURGE OVERRIDE button 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.
