Pre-Installation
Inspection
Visuallyinspectthecartonfordamages.Ifitisdamaged,
notifytheappropriatecarrierimmediately.
Openthecartonandvisuallyinspectthedeviceforobvious
defects.Returndamagedordefectiveproducts.
Required Installation Items:
• WiringdiagramforMicroTechIIIUnitController
Tools
 ■ Appropriatescrewdriver(s)forcover,terminals,and
mountingscrews
 ■ Wirestripper/cutter
The following only if wallboard mounting:
 ■ Appropriatedrillanddrillbits
 ■ Appropriatemountingscrewsandplasticanchors
Wiring
3-leadNECClassIIlowvoltagewiringfortemperaturesen-
sor669529001,5-leadforsensor669529101and669529201.
Notes: 1.Do not install the wire cables in the same conduit
with power wiring.
2.Never apply external voltage of any type to any
terminal or damage will result.
3.Do not exceed ratings of the device. This is a low
voltage device:
4.Always use 22-gauge wire and never locate the
room temperature sensor more than 250' from the
unit:
WiringmustbeinstalledinaccordancewiththeNational
ElectricalCodeandalllocalcodesandordinances,whichcan
requiretheuseofplenumratedcableorconduit.
Mounting Location
Locatethesensoronawallwhereexposuretounrestrictedair
circulationrepresentstheaveragetemperatureofthespace.A
commonmistakeistomountthesensortooclosetothesup-
plyairdiffuserinaroom.Thiscausesshortcyclingoftheair
conditioningunitandlargeroomtemperatureswings.
Installation
DANGER
Hazardous Voltage!
This equipment presents hazards of electricity.
Failure to read and follow these instructions can re-
sult in property damage, severe personal injury or
death.
1. Turnoffpoweratthemainservicepanelbyremovingthe
fuseorswitchingtheappropriatecircuitbreakertothe
OFFposition.
2. Removethesensorcoverbyinsertingascrewdriverand
gentlytwistingitintheslotsonthesidesofthewall
temperaturesensor(669529101&669529201only).
Toremovethecoveronsensor669529001,loosentwo
allen-wrenchsetscrewslocatedontheundersideofthe
cover.
Note: Mountthesensorvefeetabovetheoor.Donot
mount the sensor on an outside wall, in direct sunlight,
behind a door, or in an area affected by a vent or duct.
3. Placethewallsensormountingbaseagainstthewall
wherethesensorwherebelocated.Usingthebaseasa
templatetracethemountingholesontothewall.
4. Drilla3/16"holeateachmountingholemark.
5. Insertwallanchorsintomountingholesandtapintothe
wallsurface.
6. Feedwiresthroughthebackofthesensormountingbase
andalignsensormountingholeswithwallanchors.
7. Usesuppliedscrewstosecuresensorbasetowall.
CAUTION
Be certain that exposed portions of wires do not come in contact
with each other.
8. Connectstripped,labeledwirestomatchingterminalson
thetemperaturesensor.RefertoeitherFigure1orFigure
2onpage4forwiringdetails.
9. Tightenscrewsonterminalconnections.Gentlytugwire
tocheckforsecureconnections.Conrmthateachwire
isconnectedtotheproperterminal.
10. Sealtheholewherethewireentersthroughthewall
behindthetemperaturesensor,withnon-ammable
insulationorputty.
11. Replacecoveronwalltemperaturesensorbysnappingit
inplace.
12. Turnonpowertothesystematthemainservicepanel
13. Testwalltemperaturesensoroperationasdescribedin
"Testing"onpage4.
Note: Sensor 669529001 has two allen wrench set-screws
on the underside of the sensor cover to secure it in
place. Do not overtighten.

Utility Box Mounting of Sensor 669529001
1. Feedthecablefromtheutilitybox.
2. Strip1/4–inchofinsulationfromtheendofthewires.
3. Connectstripped,labeledwirestomatchingterminalson
thetemperaturesensorbase.SeeFigure2.
4. Tightenscrewsonterminalconnections.Gentlytugwire
tocheckforsecureconnections.Conrmthateachwire
isconnectedtotheproperterminal.
5. Neatlystoreexcesswirebackinsidetheutilitybox.
6. Mountthesensorbasetotheutilityboxusingtwo6-32×
5/8–inchatheadsheetmetalscrews
providedwiththesensor.
7. Replacecoveronwalltemperaturesensorbyattaching
thecatchesatthetopofthecovertothetoptabsonthe
sensorbase.Securethecovertothebasebytightening
thetwoallenwrenchset-screwsonthebottomofthe
sensorcover.Donotovertighten.

Troubleshooting
Symptom Remedy
No LED illuminated Check for 5 VDC at sensor, LED is
dark when 5 VDC is not present
Unit turns on and off too frequently
Sensor must be located as de-
scribed in "Mounting Location" on
page 3.
For Sensors 669529101 and 669529201 Only
System fan does not come on
properly
Verify wiring is correct. See "Fan
Test" on page 4.
Fan runs continuously Check fan On/Off switch, ON posi-
tion runs indoor fan continuously.
