WIRING
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 applica-
tions, trim end of wire if not straight.
If the thermostat has separate E and Aux terminals, install a jumper
between the two terminals.
3
Wires 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.

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.

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.

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