Press [AIR CLEANING] on the Home screen to enter
the Air Cleaning screen.
If installed, air cleaning can operate in five different
modes. Air cleaning will activate the fan for the purpose
of air cleaning.
Off: The air cleaner will not call the fan for the purpose
of air cleaning. Note: If air cleaning is installed, air
cleaning will still occur during normal fan operation
during heating, cooling or other indoor air quality events.
Constant Clean: This option will provide the maximum
amount of air cleaning available. The air cleaner will be
active for 24 hours a day, seven days a week.
Automatic: The air cleaner will run a minimum of
30 minutes every hour. The air cleaner will monitor
the amount of time your heating and cooling system
runs; if 30 minutes is not reached the air cleaner will
automatically turn on. This will maximize the amount of
air cleaning while minimizing energy consumption.
Event Clean (3 hour cycle): When selected, the air
cleaner will run for 3 hours continuously and then return
to the most recent mode of Off, Automatic, or Constant
Clean. This option only cleans the air when needed; an
example would be while vacuuming.
Allergies (24 hour cycle): When seasonal allergies
spike and outside air quality is at its worst, choose
this option. Your air cleaner will run continuously for
24 hours, then return to the most recent mode of Off,
Automatic, or Constant Clean.
Note: The Home Comfort Control will manage fan and
air cleaning selections when the selections overlap.

Press [HUMIDITY CONTROL] on the Home screen to
enter the Humidity Control screen.
The Humidity Control screen can be used to control both
humidification and dehumidification.
If humidification is installed it can be controlled in two
modes, automatic or manual.
Automatic or manual mode is configured by the installer.
To determined which mode the Home Comfort Control is
set to, see the diagrams on pages 15 and 17.
HUMIDITY CONTROL
In automatic mode you will receive the optimum
amount of humidity so that your home and its
furnishings are protected from the damaging effects
of excess condensation or low humidity during heating
season. The control automatically adjusts your home’s
RH based on the outdoor temperature.
The humidity setting needs to be set initially to
meet your home’s conditions. Please follow these
steps when adjusting your control.
1. Adjust the humidity setting to “3” which is within
normal range. During the next 24-48 hours it may
be necessary to adjust the setting for more or less
humidity, depending on your personal comfort and
home’s requirements.
2. During the coldest portion of the first heating
season, minor adjustments may be necessary. This is
dependent upon your home’s construction.
The relative humidity in your home will now be
accurately controlled to meet your needs and should not
need further adjustment during future heating seasons.

HUMIDITY CONTROL (CONTINUED)
If dehumidification is installed the Home Comfort
Control can be configured, through the installer setup,
to control dehumidification with either a whole home
dehumidifier or with the air conditioner (cooling unit).
The Home Comfort Control will allow you to set the
desired humidity (% relative humidity) level in your home
and can be used to turn the dehumidification On or Off.
Use the dehumidification adjustment to set the
dehumidification setpoint to 60% when first installed.
Allow dehumidification to run until the initial setpoint
is reached, before deciding if you want to change the
humidity setting.
Raise the setting if you prefer the air to be
less dry; this will reduce the amount of time that
dehumidification runs.
Lower the setting if you prefer the air to be
more dry; this will increase the amount of time that
dehumidification runs.
Your comfort is the best measure of how to adjust
your setting. When first installed, your dehumidifier
has to remove all the moisture that is initially in your
home. The home acts like a sponge so the moisture in
the materials of your home is at the same level as the
air. After drying the air, the materials of the home will
release the moisture back into the air until they are
again at the same level. As a result, it is not uncommon
for dehumidification to operate for an extended period
of time when it is first installed.
INDOOR AIR QUALITY FUNCTIONS
HUMIDITY CONTROL (CONTINUED)
Energy Saving Tip #1:
Adjust the setting to be as high as is comfortable to
reduce dehumidification run time – if it feels clammy or
smells damp or moldy lower the setting. To save energy,
turn the dehumidifier control OFF when you open your
windows just as you would with air conditioning.
Energy Saving Tip #2:
If vacating your home for an extended period in the
summer, set the relative humidity at 60% and set
the cooling setpoint as high as you are comfortable
setting it to in cooling mode. Consult with appropriate
professionals regarding the highest temperature that
is safe for your pets or possessions. This will keep
the humidity at a controlled level to help prevent mold
while minimizing the amount of the cooling energy
used. Vacation hold is a convenient way to adjust the
dehumidification and cooling setpoint when you will
be away.

Press [FRESH AIR] on the Home screen to enter the
Fresh Air screen.
If ventilation is installed, Fresh Air can operate in four
different modes.
Off: Ventilation will not run.
Automatic: Ventilation will cycle based on the
parameters set by the installer to meet your home’s
ventilation requirements.
3 Hour Event: Ventilation will be constantly energized
for 3 hours and then the fresh air mode will return to Off
or Automatic (Hourly) depending on which mode was
most recently active. This option is used when fresh air
is needed. An example would be after cooking.
24 Hour Event: Ventilation will be constantly energized
for 24 hours and then the fresh air mode will return to
Off or Automatic (Hourly) depending on which mode was
most recently active. This option is used when a large
amount of fresh air is desired. An example would be a
day with desirable outdoor conditions.

SLEEP: Temperature you would prefer while sleeping.
The times shown in the table below are the defaults. The start time and temperature of each section can be changed
to fit your schedule. (See Changing Program Schedules section on pages 26-27.)
This Home Comfort Control is pre-set to use the following program settings (see table below). We recommend these
settings, since they can reduce your heating/cooling expenses. The fan program is pre-set to AUTO for all events.
