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 .
