FOR INSTALLER & OWNER:
3. Operation
On the display screen, a solid “O” in front of any of the 3 functions (SETPOINT, VENT, FAN) indicates the
function is operating. A flashing “O” indicates it is in a wait mode and not available at the moment. No “O”
indicates the function is currently OFF.

Wait mode is a factory-programmed time period meant to prevent short cycles. This extends the life of the
dehumidifier. When a flashing “O” is encountered, the unit is in wait mode and IT COULD BE UP TO 10
MINUTES BEFORE OPERATION RESUMES.
3.1 Display
• Whenever there is power to the control, it will display the time, the day, % relative humidity, and
temperature.
• When the control is actually switched ON, the %RH setpoint, fan status, run mode (program or hold), and
fresh air ventilation status is displayed.
• When a key is pressed the display will light for approximately ½ a minute.
• The Time and Day is displayed at the top of the screen.
• RH and Temperature are displayed in real time.
• A solid “O” before the SET POINT, VENT, OR FAN indicates the function
is operating.
• A flashing “O” before the SET POINT, VENT, OR FAN indicates the unit is
in wait mode.
3.2 Setting
During the set-up process, if you make a mistake, simply continue. You can always go back to adjust the
settings. If you leave the control alone and don’t touch any buttons for 10 seconds, the control will remember
any changes made and return to the normal display screen, allowing you to proceed to the next step.
