WARNING! THE QUEST DEH 3000 DIGITAL CONTROL OPERATES ON A LOW VOLTAGE
CIRCUIT (24 VAC) AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.
WARNING! UNPLUG THE QUEST DEHUMIDIFIER BEFORE WIRING THE DEH 3000.
Theinstallermustsupplyalleldwiring,includingthewiringbetweentheQUESTdehumidierand
theQuestDEH3000.SomeofthecontrolwiresleavingtheQUESTdehumidiermaynotbeusedin
somecontrolsituationsandshouldbeleftdisconnectedwithwirenutstapedontothestrippedends.
BesuretoconsulttheelectricalschematicinthismanualortheinternalelectricalboxoftheQuest
dehumidierbeforemakinganycontrolconnections.
WARNING! ONLY CONNECT THE WHITE WIRE TO THE CONTROL IF IT IS WIRED IN A
CIRCUIT THROUGH AN ELECTRIC DAMPER, OTHERWISE TRANSFORMER DAMAGE MAY RESULT.
TheWhitewirecontrolstheoptionalmotorizeddamperthatcanbeinstalledintoafreshair
duct.Thisdamperprovidestheabilitytocontrolfresh
airventilationusingtheventilationtimerfunctionof
theQuestDEH3000andtheterminallabeled“DMP”
(SeeSection3.8).Leavethe“DMP”terminalunusedif
amotorizeddamperisnotused,andcapofftheWhite
wirefromtheQuestdehumidier.
Standard wire colors for thermostats are as follows:

2.4 Dehumidier lock-OFF or lock-ON:
A/C sensor feature
Toautomaticallyactivateordeactivatethedehumidierwhentheair
conditionerruns.
Activate dehumidication when the air-conditioner is running.
A voltmeter is required for the next steps to ensure the correct wiring from
the A/C transformer is used to set up the Lock-in dehumidier function.
1.ThecommonwirefromtheexistingA/C
transformer(usuallyBlack)mustbeattachedto
the“COM”sensorterminalbetween“ON-D”and

TIP: The common wire can be identied as the wire from
the A/C transformer that reads 0 volts between it and the
Yellow air conditioning call for cooling wire.The incorrect
wire will give a 20 to 28 volt reading.

3.6 Adjusting the relative humidity “SETPOINT”
TheQuestDEH3000sensestheambientrelativehumidity(%RH)ofthespaceinwhichitislocated,itcomes
factorypresettohold50%relativehumidity.
Therelativehumidity“SETPOINT”(desiredRHtobemaintained)operates
thedehumidierfunctionoftheQuestdehumidier.Ithasnoeffectonthe
optionalVENT(freshairventilation)orFAN(airrecirculation)functionsif
theyarebeingused.
Operation
Thestandardrangethatthedehumidierholdsaroundyour“SETPOINT”
is3%.Withasetpointof50%,thedehumidierwillrununtiltherelative
humidityreaches47%.Thedehumidierwillthenswitchoffuntilthe
relativehumidityreaches53%.

Ifthesetpointishigherthantheambientrelativehumidity,thespacedoesnotneedtobedehumidiedsothe
dehumidierwillnotrun.
Example:Setpoint:50%RH
Currentcondition:45%RH–Thedehumidierwillbeoff(no“O”indicatorwillbedisplayed).
Ifyoursetpointisbelowtheambientcondition,thedehumidierwillbeonand“O”willdisplay.
Example:Setpoint:50%RH
Currentcondition:55%RH–Thedehumidierwillbeon(“O”displayed).

3.7 Fan Setting and Operation
Usethe“FAN”buttontochangethefanoperation.Thereare2choicesforfanoperation:“ON”or“AUTO”.The
factorypresetis“AUTO”.
“ON”–ThefanintheQuestdehumidierwillruncontinuously.Thisdoesnotaffecteitherthedehumidication
orventilationfunctionsofthesystem.Thesystemmayormaynotbeventilatingordehumidifyingwhilethefanis
running.Thissettingiscommonlyusedformaximumairltrationand/orairrecirculation.
“AUTO”–IndicatesthefanwillrunwhentheQuestDEH3000callsfordehumidicationorventilation.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off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”indicates
thefanisOFF.
Tosettheoperation:
1.Pressandholdthe“FAN”button.Thecurrentfansettingwillbeginto
ashonthedisplay.Releasethebutton.
2.Pressthe“FAN”buttontotogglebetweenthe“ON”and“AUTO”modes.
Withthefaninthe“AUTO”mode,thefanwilloperateonlywhenneeded
byotherfunctionsofthesystem.ThefanwillremainOFFunlessthesystem
isdehumidifyingorventilating.Thefanalwaysrunsduringdehumidication
andventilationandthefan“O”iconwillbelit.Tocompletelyturnthe
systemOFF,usethe“ON/OFF”buttonasdescribedearlier.
3.8 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lit.
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.
