STEP2:Disassemblethe HumidifierControl
Removedoorfromthe HumidifierControlby pullingthe bottomofthe door
straightout.
STEP3:ChecktheModeSwitch
With the door removed,noticethe switch labeledBYPASSand POWER
(partiallycovered bythe enclosure).Make surethe switch is correctly set
for the humidifiermodelbeinginstalled or damageto the HumidifierControl
could result(seeSTEP12"Wiring").
STEP 4: Check the Change HumidifierPad indicatorSetting
This settingwiil controlwhen the indicatorlightturnson, remindingyou
to changeyour HumidifierPad.Ifyour Controlcamewith ahumidifier,the
Controlispre-setat position"C". If the installationsitehasa 3-month
or shorterheatingseasonor very hardwater,youmaywant toadjustthe
setting.(seeFigureB).TheControlmust beenergizedto resetthe
HumidifierPad Indicator.
STEP5:Determine Location for HumidifierControl
and Mount it
HumidifierControlmust bemountedinthe ReturnDuct.Forproper
operation,the HumidifierControlmust beatleast6inches upstreamof any
ofthe following:
.Humidifier
. HumidifierBypassDuctwork(if applicable)
.FreshAir intake Ductwork (ifapplicable)(see FigureC)

STEPG:Determine Locationfor Outdoor TemperatureSensor
Thelocationofthe OutdoorTemperatureSensormust meetthesethree requirements:
1. Must bemountedon North, Eastor West side ofhouseoutof direct sunlight
2. Must beat least 3feetfrom all exhaustvents
3. Must beaboveexpectedsnow line(SeeFigureD)
incorrect humiditylevelswill result if theserequirementsare notmet.
STEP7:Locate ExistingAccess Hole to Outside
A convenientway to get the Sensorwire outsideisto makeuseof unused
wires runningto the A/C condensingunit(if applicaNe).Otherways areto use
existing holesfor CaNeTV lines,telephone lines,A/C lines,etc. Readall
equipmentinstructions beforehandfor possiNe conflicts andwarnings.

STEP11:Determine Power Source for Humidifier Control
Determinewhere you will get 24VACto power the Humidifier Controlbasedonthe 2 optionsbelow:
OPTION1:FURNACESWiTH ACCESSORYTERMINALS.if the accessoryterminals provide:
. 24VAC:Wire these directly to the "R" and "C" terminals onthe Humidifier Control.
. 120VAC:Wire to a 24VACtransformer,which in turn connectstothe "R" and"C"
terminals onthe Humidifier Control.
in either case,the voltageto the HumidifierControlmustbe between 22VAC- 30VAC.
OPTION2: EXTERNAL24VACTRANSFORMER:
Wire into a power source otherthan the furnace
blower circuit. Thetransformer can be poweredoff
the 120VACline atthe junction box beforeit enters
the furnace.The24volt sideofthe transformer is
connectedto the "R" and "C" terminalsonthe
HumidifierControl.
NOTES: TheHumidifier Controlwill operate propedywith either a switched or continuouspowersource.
Whether using ACCESSORYTERMINALSORan EXTERNALTRANSFORMER,the minimumVArequired is; 2.0VAfor
PowerHumidifiers;or 10.0VAfor BypassHumidifiers.
When power is connectedfor the first time,the redand greenLEDswill light momentarily.
STEP12:Wiring
NOTE:The controlwill function with either aswitched or continuous24VACpower source. SeeDiagramsA-Dfor wiring options.

SYMPTOM TROUBLESHOOTING PROCEDURE
Humidifier does
not operate in
"Test" mode
*Make surefurnace blower is operating and thermostat is calling for heat.
* Make surethe OutdoorTemperature Sensor is connected to the "ODT" terminals ofthe control. (For Manual Operation,
make sure Manual Mode Resistor
Caseis in place.)
*Check wiring diagram for correct
Humidifier Control installation.
*Check voltage at Humidifier Control
"R" and "C" terminals. Voltage
should be 22VACminimum- 30VAC
maximum.
*Check Current Sensing Relay
(if used) for correct installation (see
Current Sensing Relayinstructions).
Do not use Current Sensing Relayin
transformer circuit or "R" and "C°'
circuit of Humidifier Control. Current
Sensing Relay isto be used in the
"H" circuit only.
*In"Test" mode, humidifier will
operate for 1minute only. DO NOT
LEAVEIN TESTMODEAS
HUMIDIFIERWILL NOTOPERATE
WARNING
Sharpedges onthe opening may causecuts. Usecarewhen cutting the plenum opening
and installing the Humidifier Control.
CAUTION
* Donot mount Humidifier Controlon supply plenum OFduct. Theunit will not withstand
supply temperatures and will malfunction!
* When installing Humidifier Control on counterflow furnaces, ensure blower continues
to run after a heat call issatisfiedto eliminate hightemperatures from damagingthe
Humidifier Control.
* Donot mount HumidifierControldownstream of the bypassoutlet. Falsehumidity
conditions will causehumidifier to operate incoFrectly.

TROUBLESHOOTINGPROCEDURE
"Change Humidifier Pad" •Callyour installerto have your Humidifier Pad changed, or visit your installerto purchase a new Humidifier Pad.
Indicator is lit. Followthe instructions on the Humidifier Pad box.
Humidifier operates only
in "Test" mode •If outdoor temperature isgreater than 60°For less than -30°F,the Humidifier Control will
only operate inthe "Test" mode. (For One Minute)
•Ifthe humidity level inthe home ishigherthan the knobsetting, the Humidifier Control
will not operate the Humidifier.
•Checkthe resistance of the sensor by removing the leads ofthe OutdoorTemperature
Sensorfrom the terminals and measuring the resistance across the wires with an
ohmmeter. Compare reading to outdoor temperature inTable 1.(For Manual Operation,
verify that resistance across the leads of Manual Mode Resistor Case isbetween 44,000
and48,000ohms).
•Make sure the OutdoorTemperature Sensor is mounted completely outside the house
onthe North, East,or West side ofthe house and out of direct sunlight. (Automatic
Mode Only)
•If Outdoor Temperature Sensor ismounted infresh air intakeduct, make surethe probe
isno morethan 36 inchesfrom the outside wall. (Automatic Mode Only)
•Make sure the OutdoorTemperature Sensor is located at least 3feet away from all
exhaust vents. (Automatic Mode Only)

constantly the humidity level is higher than the knob setting.
•Inthe "Test" mode, verify unit will operate for approximately one minute.
•Checkthe resistance ofthe Outdoor Temperature Sensor asinstructedabove.
•Make sure the Outdoor Temperature Sensor ismounted completely outside the house onthe North, East,or West
side of the houseand out of direct sunlight. (Automatic Mode Only).
•Rotatethe Humidifier Control knob counterclockwise to the "Off" position, and observe whether the humidifier turns
off. Ifthe humidifier still operates in the "Off" position, _erformthe following:
1. Checkwiring diagram for correct Humidifier Control Installation.
2. Removewires from Humidifier Control's "H" terminals. If Humidifier continues to operate, replace solenoid valve.

(See FigureH) .Checkthat the wiring iscorrect.
Measure the resistance of the Outdoor Temperature Sensor by
removingthe leads from the terminal and measuring the resistance
across the wires with an ohmmeter. Confirmthe reading with the
temperature inTable 1.(ForManual Operation, verify that the
resistance across the leads ofthe Manual Mode Resistor Caseis
between 44,000and 48,000ohms).
