“ON”–ThefanintheUltraAiredehumidierwillruncontinuously.Thisdoesnotaecteitherthe
dehumidicationorventilationfunctionsofthesystem.Thesystemmayormaynotbeventilatingor

Ifthecontrolhasnotcalledfordehumidicationfor3hours,thecontrolwillautomaticallyrunthe
dehumidierfanfor10minutes.
Afteradehumidicationcycle,thefanautomaticallyshutsofor10minutes.Thispauseallowsthewaterto
drainfromthedehumidier.
Asolid“O”indicatesthefanisoperating.Aashing“O”indicatesthefanisinawaitmode.No“O”

Damper Operation and Ventilation, Manual (Hold) Mode
The“VENT”settingcontrolstheventilationfunctionofthesystem.Ithas
nocontroloverthedehumidicationfunction.Inordertoprovide
ventilation, the motorized damper must be open and the fan must be
running. The controller takes care of these two functions automatically
so that whenever the damper is open, the fan is running.
Theventilationindicator“O”willbedisplayedwhenevertheunitis
ventilating.Thefanoperationindicator“O”willalsobedisplayed.
There are three damper operation modes:
1. “OPEN”–holdmode:Thedamperwillbeopenandthedehumidier
fan will be continuously operating to introduce fresh air into the space.
Use this mode for continuous fresh air ventilation. The fan is always
on when the damper is open.
2. “CLOSED”–holdmode:Thedamperwillneveropen,andthe
dehumidierwillnotventilate.Thefanwillstilloperatenormallyfor
recirculationanddehumidication.
3. “PROGRAM”mode:TheDEH3000/Rwilloperatethemotorized
damperandthedehumidierfanaccordingtotheprogrammed
ventilationschedule(Page14).
Thefactorypresetforthe“VENT”settingis“CLOSED”.
To set “OPEN” – hold or “CLOSED” – hold ventilation operation:
1. Pressthe“VENT”button.Thecurrentsettingwillbegintoashonthedisplay.Releasethebutton.
2. Pressthe“VENT”buttonagaintoswitchbetween“OPEN”and“CLOSED”.
