Home And SyStem StAtuS iconS
The following icons are located on home screen and will appear during applicable operations or tasks.
Table 1. System Icons
Icon Function Screen Text Purpose
Navigation Menu Selecting this icon will bring up user and installer
menus.
Function Away
When the away icon is touched, the system will auto-
matically 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.
System
Status Heating System is heating the home.
System
Status Cooling System is cooling the home.
System
Status Humidifying
If humidication equipment is installed and congured,
the system will display this message when adding hu-
midity to the air in the home.

Table 1. System Icons
Icon Function Screen Text Purpose
System
Status Dehumidifying
The system can be used in cooling mode to help re-
move 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.
System
Status Defrosting The system is defrosting the outdoor unit coil (only
when required). Heat pump only.
System
Status Emerg. 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 pro-
vided by the indoor unit. Other sources could be gas,
oil, or hot-water back-up systems as well. The sup-
plemental 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 sup-
plemental heat (2nd stage) by itself, without the use of
your heat pump (1st stage heat). Not available for non-
heat pump systems.
System
Status Aux. Heat
Is only available with heat pump system. If outdoor tem-
perature 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 aux-
iliary 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.

Table 1. System Icons
Icon Function Screen Text Purpose
System
Status Will start soon
A ve minute safety delay prevents the compressor
from operating too soon after shut-down to allow inter-
nal pressures to equalize.
System
Status Ambient lockout
This indicates that either the outdoor temperature is
above or below the balance point temperature settings.
The low balance point setting prevents heat pump heat-
ing 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 be-
low for example, only auxiliary heating (electric or gas)
is used.
If the high balance point is set to 50°F (10°C ) for exam-
ple, which is also adjustable by your dealer, then aux-
iliary 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.
Function Transitioning to
next schedule
The system is following an active schedule and is tran-
sitioning to the next temperature setting based on a
time indicator.

Function System Under
Test
Typically occurs when the system has had a power in-
terruption. 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.
Function
Load shedding,
wait time 45
min
Load shedding is where the utility company turns off
you outdoor unit in peak times for a specied period of
time to help spread the electrical system load for the
area. Your system will resume operation in 45 minutes.
