is running in Heat • Cool mode (auto-changeover).

Away
When the away icon is touched, the system will
automatically use energy saving settings - heat-to 62
(16.5) and cool-to 85 (29.5). Temperatures can be
adjusted by pressing on the available temperature
setting (i.e., heat-to or cool-to). To exit away, press the
cancel icon. In a zoning system, all zones are set to
a single heat-to and cool-too setting. Note that when
manually selecting Away from the home screen, the
Smart Away feature (if enabled under settings) will be
temporally disabled until Away is canceled. See page
10 for additional information.

Humidifying
If humidication equipment is installed and congured,
the system will display this message when adding
humidity to the air in the home.
Dehumidifying
The system can be used in cooling mode to help
remove excessive humidity as determined by the user
setting. Go to menu > settings > humidity > and turn on
dehumidify. Then adjust the acceptable low and high
humidity levels in the home with the dehumidication
set-point slider.
Defrosting
The system is defrosting the outdoor unit coil (only
when required).
Emergency Heat
All heat pumps operating in northern climates below
35°F (1.6°C) normally need a supplemental heating
source. Usually it is in the form of electric heating
provided by the indoor unit. Other sources could be
gas, oil, or hot-water back-up systems as well. The
supplemental heat is also referred to as “second-stage”
or “back-up” heating, with “rst-stage” being the heat
pump only. Emergency heat is when you use your
supplemental heat (2nd stage) by itself, without the use
of your heat pump (1st stage heat). Not available for
non-heat pump systems.
Auxiliary Heat
Is only available with heat pump system. If outdoor
temperature is above the high balance point, only the
heat pump will operate - default 50°F (10°C) high. If
outdoor temperature is below the low balance point,
only auxiliary heating will operate - default 25°F
(-4.0°C) low. If outdoor temperature is in-between the
high and low balance point, both the heat pump and
auxiliary heat sources can operate.
Will start soon
A ve minute safety delay prevents the compressor
from operating too soon after shut-down to allow
internal pressures to equalize.
