Purpose
Selecting this icon will bring up user and installer
menus.
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.
System is heating the home
System is cooling the home.
If humidification equipment is installed and configured,
the system will display this message when adding
humidity to the air in the home.
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 dehumidification set-point slider.
The system is defrosting the outdoor unit coil (only when
required).
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
"first-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.

Purpose
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.
A five minute safety delay prevents the compressor from
operating too soon after shut-down to allow internal
pressures to equalize.
This indicates that either the outdoor temperature is
above or below the balance point temperature settings.
The low balance point setting prevents heat pump heating
below the set point and back up heat will be used.
Typically the default is 25°F (-4.0°C), but that setting can
be adjusted by your dealer. At 25°F (-4.0°C) or below for
example, only auxiliary heating (electric or gas) is used. If
the high balance point is set to 50°F ( 10°C ) for example,
which is also adjustable by your dealer, then auxiliary
heat will not be allowed. Only heat pump heating will be
used. Anytime the outdoor temperature is below or above
the balance point temperature settings, the ambient
lockout notice will appear on the home screen.
The system is following an active schedule and is
transitioning to the next temperature setting based on a
time indicator.
When Internet weather is enabled and pollen count is
high in the home's location, the fan will run between
heating or cooling systems to help clean the air.
Typically occurs when the system has had a power
interruption. The thermostat starts to look for the indoor
and outdoor controls. Sometimes the outdoor control
takes longer to boot up and therefore does not respond to
inquiry by the thermostat. Recycle power to system may
resolve issue.
