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 could result in serious injury from electrical shock.

THESE iNSTALLATiON iNSTRUCTiONS ARE FORTHE HUMIDiTRAC TMHUMiDiFiER CONTROLONLY!

ForHumidifier installation, follow Humidifier Installation instructions.

/A

STEP1: Unpack the Humidifier Control Carton

Make sure all components are present (see FigureA):

A. HumidifierControl D. ResistorCase

B. OutdoorTemperature Sensor E. Manual Label

C. Sensor Shield

STEP2:Disassemble the Humidifier Control

Removeknob,then pull cover offthe base. FigureA

STEP3:Checkthe Jumper Blocks

With the cover removed,notice 5 pins coming upfrom the base. Make sure the 2 sets of

jumper blocks are correctly set for the type of humidifier being installed (see FigureB).

STEP4: MountHumidifier Control

FAN-POWERED HUMIDIFIER

3UMPER

Control must be mountedin the Return Duct.For properoperation, the

Controlmust be atleast 6 inches upstreamof any of the following:

* Humidifier

*HumidifierBypass Ductwork(if applicable)

* FreshAir Intake Ductwork (if applicable) (see Figure C)

BYPASS HUMIDIFIERS Figured

HDMDI I R

Usethe perforated HumidifierControl template (attachedto these instructions)to marl<

the duct opening and cut it. Use4 sheet metal screws (not provided)

to mountthe Control in the duct opening and make sure Control is sealed tightly to duct.

STEP 5: Determine Locationfor OutdoorTemperatureSensor

The OutdoorTemperatureSensor:

1. Must be mounted on North,Eastor West side of house out of direct sunlight

2. Must be at least3 feet from all exhaustvents

3. Must be aboveexpected snow line (Seefigure D)

Incorrect humiditylevels will result if these requirementsare not met.

STEP6: Locate Existing Access Hole to Outside

A convenientway to get the Sensorwire outside is to make

use of unusedwires running to the A!C condensing unit

(if applicable).Otherways are to useexisting holesfor

Cable11/lines, telephone lines,A/0 lines, etc. Readall 'EADD

equipment instructions beforehand for possible conflicts

and warnings.

OR

6 inch fresh air intake duct

in bethcases,the Sensormust be nofurther than3 feet fromthe outside wall. See FigureE,

In either case,do not run OutdoorTemperature Sensorwire alongsidewires carrying high voltage (120VACor higher).

STEP9: Wiring

NOTE:The control will function with either a switched or continuous 24 VACPower source.

1. Forsystemtest, be sure that 24VACis appliedto the 24VAC

terminals of HumidifierControl.

2. Putthe cover and knob back onto HumidifierControl base.

3. Activate furnace blower andbesure thermostatis callingfor heat.

4. Rotatethe control knob of HumidifierControlclockwise to the

"Test" position.

5. If all isset up properly,you should be able to hearthe solenoid

1 minute.

6. If the humidifier does netactivate with the Humidifier Controlin

the "Test" position,refer to troubleshooting guide.

7. Settingthe HumidifierControl:

•If homeis occupied, set Humidifier Controlto "Normal"

•If homeis vacant, set HumidifierControlto "Off"

8. Inform homeownerto set the HumidifierControlto "Normal"

(position5) for the initial adjustmentperiod. Oncethe Humidifier

Controlis properlyadjusted, no further adjustmentis necessary!

operate in "Test" mode

,Make sure furnace blower is operating and thermostat is calling for heat.

, Make sure the OutdoorTemperatureSensor is connected tothe "Outdoor Temperature Sensor" terminals of the control.

, Check mainwiring diagramfor correct Humidifier Controlinstallation.

, Check voltage at Humidifier Control24 VACterminals. Voltage should be 22VACminimum-30 VAC maximum.

•Check Humidifier Controlfor correct installation of jumper blocks.

•Check Current Sensing Relay(if used)for correct installation. Donot use Model 50Relayin transformer circuit or "24 VAC"

circuit of Humidifier Control.Model 50relay is to be usedin the "A/A" circuit only.

•In"Test" mode,humidifierwill operatefor 1 minuteonly. DONOTLEAVEIN TESTMODEAS HUMIDIFIERWILL NOTOPERATE.

in "Test" mode

• If outdoor temperature is greater than 65°For less than -32°F,the HumidifierControl will

only operate inthe "Test" mode.(Automatic Mode Only)

• If the humidity level inthe homeis higher than the knobsetting,the HumidifierControl

will notoperate the Humidifier.

• Check the resistance of the sensor by removingthe leads of the OutdoorTemperature

Sensorfromthe terminals and measuringthe resistance acrossthe wires with an ohmme-

ter. Confirm reading to outdoor temperature in Table 1.

• Make sure the OutdoorTemperatureSensoris mountedcompletely outside the house

on the North, East,or West side of the house and out of direct sunlight.

• If OutdoorTemperature Sensor is mounted infresh air intake duct, make sure the probe

is nofurther than 36inches from the outsidewall.

• Make sure the OutdoorTemperature Sensoris located at least3 feet away from all

exhaustvents.

Humidifieroperates • If the humidity levelin the homeis lessthan the knob setting,the HumidifierControlwill

constantly operate the Humidifier until the humidity level is higherthan the knob setting.

, In the "Test" mode,verify unit will operatefor approximatelyone minute.

, Check the resistance of the sensor by removingthe wires ofthe Outdoor Temperature

Sensor and measuringthe resistance acrossthe wires with an ohmmeter.Compare

measurementto outdoortemperature in Table 1.

• Make sure the OutdoorTemperatureSensor is mountedcompletely outside the houseon

, Rotatethe HumidifierControl knobcounterclockwise to the "Off" position, and observe

whether the humidifierturns off.If the humidifier still operates in the "Off" position,

performthe following:

1. Checksummary wiring diagramfor correct HumidifierControl Installation.

2. Removewires from Humidifier Control's"A/A" terminals. If Humidifier continues

to operate, replace solenoid valve.

WARNING

Sharp edgeson the opening may cause cuts. Use care when cutting the plenum opening

and installing the Humidifier Control.

CAUTION

• Do not mount Humidifier Control on supply plenum or duct. Tile unitwill =rotwithstand

supplytemperatures and will malfunction!

• When installing Humidifier Control on counterflow furnaces, ensure blower continues

to run after a heat call issatisfied to eliminate hightemperatures from damaging the

Humidifier Control.

• Donot mount Humidifier Control downstream of the bypassoutlet. FalsehumiditV

conditions will cause humidifier to operate incorrectly.
