•   The humidity setting cannot be changed when the control is OFF.

•   The first press of either the

the LCD.

•   Each subsequent push of the up or down

buttons will change the setting by 1%.

•   When the measured humidity is greater than the setting, the control will turn on the dehumidifier and ON will blink on the LCD display.
•   When the measured humidity falls 3% below the setting, the control will turn off the dehumidifier and ON will stop blinking, but remain

displayed on the LCD.

•   The dehumidifier will turn off if one of the control limits has been exceeded.
•   If the control measures a dew point below 40°F OR a temperature above 99°F, the control will deactivate the dehumidifier output if actively

dehumidifying, the dehumidifier will stop dehumidifying, and 

ON and 

 will blink on the LCD screen (see 

Figure 2). 

•   The control will resume normal operation when conditions fall back within the control limits.

The control limits are used to make sure the dehumidifier does not run when conditions are outside of the operating limits. Dehumidifiers are not 

as effective when conditions are outside of the operating limits. For example, the dehumidifier will not remove much moisture when conditions 

are cool and dry. Control limits allow the dehumidifier to work efficiently within the operating range and turn off when conditions are outside of 

these limits. 
•   Dew Point Lower Limit: 40°F
•   Temperature High Limit: 99°F
