If dehumidification is installed the Home Comfort
control can be configured, through the installer set-up,
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 .

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.
