the dehumidification setpoint .

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 .
Done when
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 . Set the Dehumidifier Control to
your windows .
Energy Saving Tip #2: If your home will be unoccupied for an extended
period during the summer, set the Dehumidifier Control setpoint to 60%
RH and your cooling setpoint as high as you feel comfortable . Consult
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 while you are away .
