SETTING THE DESIRED HUMIDITY LEVEL

The dehumidifier on-board control will display the humidity setting when not running, and 
displays the measured humidity when running.

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 dehumidifier ON or OFF.
Set the control at 55%RH when first 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 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 moisture back into the air until they are 
again at the same level. As a result, it is not uncommon for the dehumidifier to operate for an 
extended period when first installed.

HOW DOES THE DEHUMIDIFIER WORK?

When the dehumidifier turns on, the blower circulates the air for 3 minutes before measuring the 
humidity level of the air. The on-board control will display AIR SAMPLING, along with the measured 
humidity on the control screen. 

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 dehumidifier to turn on the heating and cooling system blower when the dehumidifier turns on 
to allow for improved circulation of the dry air. 

ENERGY SAVINGS TIPS 

Energy Savings Tip #1:

 Adjust the 

humidity setting to be as high as is 
comfortable to reduce dehumidifier 
run time. If it feels clammy or “smells 
musty”, lower the humidity setting. To 
save energy, turn the dehumidifier 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.

Once per hour the dehumidifier 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 dehumidifier will dehumidify the air until the humidity level drops below the setting. 

NOTE:

 The dehumidifier will 

continue to dehumidify until the humidity level is 3%RH below the setting.
