Safety and Installation Instructions
READ COMPLETE INSTALLATION INSTRUCTIONS AND TEMPLATE BEFORE STARTING,
Attention Installer: This product must be installed by a qualified heating and air conditioning contractor.
Failure to do so couldresult in serious injury from electrical shock.

_._A
STEP1:Unpack the Humidifier ControlCarton
Make sure all componentsare present(seeFigureA):
A. HumidifierControl
B. OutdoorTemperatureSensor
C. SensorShield
STEP2:Disassemble the Humidifier Control
Removeknob,then pull coveroffthe base•

Figure A
STEP3:Check the Jumper Blocks
With the coverremoved, notice 5 pinscomingup from the base.Make surethe 2sets of
jumper blocks are correctlysetfor theP/pe of humidifierbeing installed(seeFigureB).
STEP4: Mount Humidifier Control
Controlmustbemounted inthe ReturnDuct.Forproperoperation,the
Controlmust be atleast 6inches upstreamof anyof the following:
• Humidifier
• HumidifierBypassDuctwork(ifapplicable)
• FreshAirIntakeDuctwork(if applicable)(see FigureC)
Usethe perforated HumidifierControltemplate(attachedto these instructions)to mark
the ductopeningand cutit.Use 4 sheetmetalscrews (notprovided)
to mountthe Control intheduct openingand makesureControl is sealeddghtJyto duct.

STEP5:Determine Location for Outdoor Temperature Sensor
TheOutdoorTemperatureSensor:
1. Must bemountedon North,EastorWest sideof houseout ofdirect sunlight
2. Must beat least 3feet from all exhaustvents
3. Must be above expectedsnow line (Seefigure D)
Incorrect hamid_ levels will resultif these requirements are not met.
STEP6:Locate Existing Access Hole to Outside
Aconvenientway to get the Sensorwire outsideis to make
useofunusedwires runningto the NC condensingunit
(if applicable).Otherwaysare to useexistingholesfor
CableTVlines,telephonelines,A/Clines, etc. Readall
equipmentinstructionsbeforehandfor possibleconflicts
andwamings.

STEP7: Alternate Location for Outdoor Temperature Sensor
The Sensor canalsobe mounted in thecenter of either:
•2 inchPVCfresh air intakepipeforthe furnace
OR
•6 inchfreshair intakeduct
In bothcases,the Sensormustbe nofurther than3feet fromthe outsidewall, SeeFigureE.

TROUBLESHOOTINGPROCEDURE
•Make sure furnace blower is operatingandthermostatis callingfor heat.
•Make sure the OutdoorTemperatureSensor is connectedto the "OutdoorTemperatureSensor"terminalsof thecontrol.
• Check mainwiring diagramfor correctHumidifierControl installation.
•Check voltageat HumidifierControl24 VACterminals.Voltageshould he 22VACminimum- 30VACmaximum.
•Check HumidifierControlfor correctinstallationofjumperblocks.
• Check Current Sensing Relay(if used)for correctinstallation.Do notuse Model50 Relayintransformercircuitor "24 VAC"
circuitof HumidifierControl.Model50 relay isto be usedinthe "A]A" circuitonly.
•In"Test" mode,humidifier will operatefor 1 minuteonly.DONOTLEAVEINTESTMODEASHUMIDIFIERWILL NOTOPERATE.

in "Test"mode
•If outdoortemperatureis greaterthan65°Forlessthan-32°F,theHumidifierControl will
only operate inthe "Test" mode.(AutomaticMode Only)
• If the humiditylevel inthe homeis higher than the knob setting, the HumidifierControl will
not operate the Humidifier.
• Check the resistance ofthe sensor by removingthe leads of the OutdoorTemperature
Sensorfromthe terminals and measuringthe resistance across the wires with an ohmmeter.
Confrm readingto outdoor temperature inTable 1.
• Make sure the Outdoor TemperatureSensor is mounted completely outside the houseon
the North, East,or West side of the house and out of direct sunlight.
• If OutdoorTemperature Sensor is mounted in fresh air intake duct, make surethe probe
is nofurther than 36 inchesfrom the outsidewall.
