Operation; Checkout - Honeywell TRUEZONE HZ322 Installation Manual

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.
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 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 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 fan.
EM HEAT Solid when in emergency heat mode. This light does not indicate a call

Steps 3–10 cycle through heating and cooling stages and open and close dampers to verify proper operation.
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.
