HUMIDITRACTMHUMIDIFIERCONTROL Safety READ COMPLETE and Installation INSTALLATION Attention Installer: Instructions INSTRUCTIONS AND TEMPLATE BEFORE STARTING, This product must be installed by a qualified heating and air conditioning contractor. Failure to do so could result in serious injury from electrical shock. THESEINSTALLATION INSTRUCTIONSAREFORTHEHUMIDITRAC TM HUMIDIFIERCONTROL ONLY! ForHumidifierinstallation,follow HumidifierInstallationInstructions, _._A STEP 1:Unpack the Humidifier Control Carton Make sure all componentsare present(see FigureA): % A. HumidifierControl B. OutdoorTemperatureSensor C. SensorShield STEP2: Disassemble the Humidifier Control Figure A Removeknob,then pull coveroffthe base• STEP3: Check the Jumper Blocks With the coverremoved, notice 5 pinscomingup from the base.Make surethe 2 sets of jumper blocks are correctlysetfor the P/pe of humidifierbeing installed(see FigureB). STEP4: Mount Humidifier Control Control mustbemounted inthe ReturnDuct.Forproperoperation,the Controlmust be at least 6 inches upstreamof anyof the following: • • • FigureB Humidifier Humidifier BypassDuctwork(ifapplicable) FreshAir Intake Ductwork(if applicable)(see FigureC) Usethe perforated HumidifierControltemplate(attachedto these instructions)to mark the ductopeningand cut it. Use 4 sheetmetalscrews (notprovided) to mountthe Control in the duct openingand makesure Control is sealeddghtJyto duct. STEP5: Determine Location for Outdoor Temperature Sensor TheOutdoor TemperatureSensor: 1. Must be mountedon North,East orWest sideof house out ofdirect sunlight 2. Must be at least 3feet from all exhaust vents 3. Must be above expectedsnow line (Seefigure D) Incorrect hamid_ levels will result if these requirements are not met. STEP6: Locate Existing Access Hole to Outside A convenientway to get the Sensorwire outsideis to make use ofunusedwires runningto the NC condensingunit (if applicable).Otherwaysare to use existingholesfor Cable TVlines,telephonelines,A/C lines, etc. Readall equipmentinstructionsbeforehandfor possibleconflicts andwamings. OUCT FigureC STEP7: Alternate Location for Outdoor Temperature Sensor The Sensor canalso be mounted in the center of either: • 2 inchPVCfresh air intake pipeforthe furnace OR • 6 inchfreshair intake duct M < 7 ,...... In bothcases,the Sensormust be nofurther than3feet fromthe outsidewall, SeeFigureE. FigureE a _6,, MAX -- OUTSIDE WALL STEP8: Routethe Wire to Chosen Sensor Location Hunwire tothe OutdoorTemperatureSensor.If sensoris outdoors,snapthe probeendof the Sensor intothe SensorShield, andattachtothe house. l_p ofSensor mostbe completelycoveredbythe Shield.The OutdoorTemperatureSensor is notaffectedbylead length. In eithercase,do not runOutdoorTemperatureSensorwire alongsidewires carryinghighvoltage(120VACor higher).

Model 50 relay is to be usedin the "A]A" circuitonly. • In "Test" mode,humidifier will operatefor 1 minute only.DO NOTLEAVEIN TESTMODEAS HUMIDIFIERWILL NOTOPERATE. Humidifieroperatesonly in "Test"mode • If outdoor temperatureis greaterthan65°For lessthan -32°F,the HumidifierControl will only operate in the "Test" mode.(AutomaticMode Only) • If the humidity level in the home is higher than the knob setting, the Humidifier Control will not operate the Humidifier. • Check the resistance ofthe sensor by removing the leads of the OutdoorTemperature Sensorfrom the terminals and measuringthe resistance across the wires with an ohmmeter. Confrm reading to outdoor temperature in Table 1. • • • Make sure the Outdoor TemperatureSensor is mounted completely outside the house on 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 no further than 36 inchesfrom the outsidewall.

Humidiferoperates constantly In the "Test" mode,verifyunitwill operate for approximatelyone minute. Checkthe resistanceof the sensorbyremovingthe wires ofthe OutdoorTemperature Sensorand measuringthe resistanceacrossthe wires with anohmmeter.Compare measurementto outdoor temperaturein Table 1. Make surethe OutdoorTemperatureSensor ismountedcompletelyoutsidethe houseon the North,East,orWest sideofthe houseandoutofdirectsunlight.. Rotatethe HumidifierControlknobcounterclockwiseto the "Off"position,and observe whetherthe humidifierturnsoff.If the humidifierstill operatesin the "Off" position, performthe following: 1. Checksummarywiring diagramfor correctHumidifier ControlInstallation. 2. Removewires from HumidifierCoutrol's"NA" terminals.If Humidifier continues to operate, replacesolenoidvalve. Humidifier or Humidifier Control "chatters"or clicksON andOFFrapidly • • Checkfor steady 22VAC- 30VACwith voltmeter. Make sure OutdoorTemperatureSensor wiringis notrunalongsidewires carryinghighvoltage(120VACor higher). .......................................................................................................................................
