Setting the Desired Humidity Level
The dehumidier on-board control will display the humidity
setting when not running, and displays the measured
humidity when running.
How Does the Dehumidier Work?
Once per hour the dehumidier will measure the humidity
level of the air and compare it to the humidity setting. If
the humidity in your home is higher than the setting, the
dehumidier will dehumidify the air until the humidity level
drops below the setting.
When the dehumidier turns on, the blower circulates the
air for 3 minutes. The on-board control will display AIR
SAMPLING, along with the measured humidity on the
control screen. At the end of this 3 minutes, the measured
humidity level of the air is compared to the humidity setting.
If the humidity of the air is higher than the setting,
the compressor turns on and the control will display
DEHUMIDIFYING, along with the measured humidity on
the control screen.
OPTIONAL – HEATING AND COOLING SYSTEM
BLOWER OPERATION
Your installing contractor may have configured the
dehumidier to turn on the heating and cooling system
blower when the dehumidier turns on to allow for improved
circulation of the dry air.
The UP and DOWN arrow buttons allow the humidity level
to be set from 40% to 80% relative humidity. Use the ON/
OFF button to turn the dehumidier ON or OFF.
Set the control at 55%RH when rst installed. Allow the
dehumidifier to run until it reaches the setting before
deciding if you want to change the setting.
• If you prefer the air to be more dry, decrease the
humidity setting.
• If you prefer the air to be less dry, increase the humidity
setting.
Your comfort is the best measure of how to adjust your
setting. When rst installed, your dehumidier 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 moisture back into
the air until they are again at the same level. As a result, it
is common for the dehumidier to operate for an extended
period when rst installed.
ENERGY SAVINGS TIPS
Energy Savings Tip #1: Adjust the humidity setting to be as
high as is comfortable to reduce dehumidier run time. If it
feels clammy or “smells musty”, lower the humidity setting.
To save energy, turn the dehumidier to OFF when you
open your windows, just as you would with air conditioning.
Energy Savings Tip #2: If vacating your home for an
extended period in the summer, set the RH at 55% and set
your thermostat as high as you are comfortable setting it to
in the 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 while minimizing the amount of cooling energy used.
