allowed:
Thermostat to HVAC Equipment
18 AWG 20 AWG 22 AWG
1250 ft/380 m 800 ft/240 m 500 ft/150 m
INSTALLATION CONSIDERATIONS
Thethermostatrequiresnobatteries.Thethermostatis
notapowerstealingdeviceandMUSThavebothRandC
terminalsconnected.SeeDiagram1.
INSTALLATION
Thermostat Location
Thermostatshouldbemounted:
• Approximately5ft.(1.5m)aboveoor.
• Closetoorinafrequentlyusedroom,preferablyon
aninsidepartitioningwall.
• Onasectionofwallwithoutpipesorductwork.
Thermostat should NOT be mounted:
• Closetoawindow,onanoutsidewall,ornexttoa
doorleadingtotheoutside.
• Exposedtodirectlightandheatfromalamp,sun,
replace,orothertemperature-radiatingobjectwhich
maycauseafalsereading.
• Closetoorindirectairowfromsupplyregisters
• Inareaswithpooraircirculation,suchasbehinda
doororinanalcove.
Thermostat Installation
1. TurnSystemPowerOff.
a. Gototherelevantcircuitbreakerpaneland
switchtheequipmentbreakersoff.
b. Toconrmpowerisoff,checkvoltagewith
voltmetertoensurethatthepowerhasbeen
successfullyshutoffbeforeproceedingto
nextstep.
Disconnect electric power to the HVAC system before
installing this product. Failure to do so could result in
electric shock and/or equipment damage. All wiring must
conform to you local electrical code.
⚠ CAUTION
If you are replacing a current communicating
thermostat continue with the next step, if you are
installing a new system skip to step 5.
2. Removethefaceplateofthecurrentthermostat.Most
faceplatessnapofforfeaturesmallscrewsthatwill
needtoberemoved.
TIP: Before disconnecting any wires, take a photo
of the current wire conguration with your mobile
device.
MERCURY NOTICE: This product does not contain
mercury. If you are replacing a product that
does contain mercury, contact your local waste–
management authority for disposal instructions.
Do not discard the old product in the regular trash.
3. LabelandDisconnectWires.
Onebyone,applyalabeldesignatedtoeachwire
connectedtothebackplateofthecurrentthermostat
thendisconnectthewirefromthecurrentthermostat
backplate.

TIP: Wrap the wires around a pen or
pencil to keep them from falling inside
the wall.
4. Removethecurrentbackplate.
5. Mountthenewbase.
a. Gentlyseparatethedisplayfromthebaseofthe
newthermostatbypullingthermostatstraight
awayfromthebase.
b. Positionthebaseagainstthewallanddetermine
ifwallanchorsfromcurrentthermostatalignwith
screwlocationsofnewbase.
c. Ifbasedoesnotalignwithexistinganchorholes,
marknewscrewlocationswithapencil.
• Drywall:Drill3/16”holefortheanchor.
• Plaster:Drill7/32”holefortheanchor.
d. Pullwiresthroughopeninginbaseandsecureto
thewallusingprovidedscrews.
TIP: Use a level to ensure thermostat
is properly aligned.
6. Connectwires.
a. Matchyourwirecongurationtotheterminalson
thebase.ReferenceDiagram1.
b. Connecteachwireindividuallybypushingdown
onthequickconnecttab,insertingthewireinto
theconnectoropening,andthenreleasingthetab.
c. Ifremoteindoorand/oroutdoorsensorsareused,
theymaybeconnectedatthistime.
TIP: Use pliers to straighten wire before
inserting into new base. Be sure to cut any
excess wire so that the insulation extends
to the terminal block. When the wire is
installed properly to the terminal block,
there should be no copper exposed.
22 AWG shielded wire is required when installing a
remote sensor further than 100 ft (30.5 meters).
7. Attachthethermostatface.
a. Alignthethermostatfaceusinghingeguideontop.
b. Rotatethethermostatdownuntiltabalignswith
holeinbase.
c. Installsecurityscrewifnecessary.
8. Returnpowertosystem.
