Lennox iComfort S30 User Manual page 5

E. This area displays various functions that are either pending or currently
active. Indicators are humidifying, dehumidifying, cooling, heating, ambient
lockout, emergency heat, cleaning air, transitioning to next schedule, load
shedding and fan is running. Indicators:
S
Heating - System is heating the home.
S
Cooling - System is cooling the home.
S
Humidifying - If humidification equipment is installed and configured,
the system will display this message when adding humidity to the air
in the home.
S
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
dehumidification set-point slider.
S
Defrosting - The system is de-icing the outdoor unit coil (only when
required).
S
Emergency heat - All heat pumps operating in northern climates
(below 35°F) 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.
S
Aux. 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 high). If outdoor temperature is below the low
balance point, only auxiliary heating will operate (Default 25°F low). If
outdoor temperature is in-between the high and low balance point,
both the heat pump and auxiliary heat sources can operate.
S
Will start soon - A 5 minute safety delay prevents the compressor
from operating too soon after shut-down to allow internal pressures
to equalize.
S
Ambient lockout - Prevents heat pump operation when outdoor
temperature is below -4°F.
S
Transitioning to next schedule - The system is following an active
schedule and is transitioning to the next temperature setting based on
a time indicator.
S
Fan is running - Displayed whenever the system is heating or cooling.
See table 3 on page 6 for fan mode descriptions.
S
Allergen Defender is working - 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. This feature can be
turned on under modes / schedules on the home screen. Select the fan
icon located in the upper right-hand of the screen.
F. Away - When away icon is touched, the system will automatically use energy
saving settings (heat-to 62 and cool-to 85). 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.
G. Pressing on the heat-to area will allow the temperature setting to be
changed.
H. Pressing on the cool-to area will allow the temperature setting to be
