WiringLabeling
Ÿ Each wire coming from the wall to the existing thermostat is connected to terminal
pointonthatthermostat.Eachof theseterminal pointsis usuallymarked withacode
letterasshowninTableAbelow.
ŸNotethatthisthermostathasmultiplefunctionterminalsthatallowSingleStageHeat
Pump capability. Standard systems use: Rh, Rc, G, Y, W.[SingleStage Heat Pumps
use:R,Y,G,andOorB.]TableAbelowshowsthemultiplefunctionsoftheterminals.
Usetheterminalsthatmatchyoursystem.
ŸThenumberofwiresinyoursystemcanbeasfewastwo(forheatonlysystems),as
many as eight, or any number in between. If you follow the labeling procedures
correctly,youdonothavetobeconcernedabouthowmanywiresthereare.
ŸThereisoftennoterminalmarkingontheexisting
thermostat of two wire, heat only systems. Just
connecteitherofthewirestotheRHterminal,then
connect the other wire to the W terminal to
completethecircuit.
ŸIMPORTANT!BEFOREDISCONNECTINGANY
WIRES, APPLY THE SELFADHESIVE LABELS
PROVIDEDTOTHEWIREASSHOWNINTABLE
ABELOW.(Forexample,attachthelabelmarked
Wtothe wirethattoestotheWorHterminalonyourexistingthermostat.)IGNORE
THECOLOROFTHEWIRESsincethesedonotalwayscomplywiththestandard.
ŸAfterlabelingwires,disconnectthemfromtheexistingthermostat.
ŸRemoveexistingwallplate.Tomakesurewiresdonotfallbackintowallopening,you
maywanttotapethemtothewall.
ŸIfholeinwallislargerthannecessaryforwires,sealthisholewithinsulatingmaterial
so that nohot orcold aircan enterthe back ofthe thermostatfrom the wall. This air
couldcauseafalsethermostatreading.

andconnectto
thermostatterminal
shown
NOTE: Do notconnect a “Common” wire(sometimes labeled “C”)to anyterminal on
this thermostat. Tape up the wire and do not use. This wire provides electricity to
nonbatterypoweredthermostats.
MountWallplateandThermostat
Ÿ Remove the wall plate from your thermostat by pressing the release tab on the
bottomofthethermostat.SeeFigure2.
Figure2.
ŸPositionwallplate onwall andpull existingwires through largeopening.Thenlevel
forappearance.Markholesfor plasticanchorsprovided,ifyourexistingholesdonot
lineupwiththoseonthewallplate.
ŸDrillholeswith3/16”bitandgentlytapanchorsintothebolesuntilflushwithwall.
Ÿ Reposition wallplate to wall, pulling wires through large opening. Insert mounting
screwsprovidedintowallanchorandtighten.SeeFigure3.
Figure3.
NOTE:5WireSystems
IfyourthermostathasonewiremarkedRorRh(2,3,or4wiresystem),thenleavethe
jumperwirebetweentheRhandRcterminalsonthewallplate.Otherwise,ifyouhave
separateRhandRcwires(5wiresystem),thenremovethejumperwirebetweenthe
RhandRcterminals.
ConnectWiresandMountThermostattoWallplate
ŸMatchandconnectthelabeledwirestotheappropriatecodedterminalscrewsonthe
wallplate.(See Figure4,5.)Ignoreanywires whichmaybe present,butwhich were
noteconnectedtotheoldthermostat.
ŸRefertotheWiringDiagramsbelowtobesureyoursystemiswiredcorrectly.
ŸIfyoursystemisasinglestageheatpumpandusesanOorBwire,youmustmove
the System Selectorswitch inside thethermostat to the Heat Pump position.If you
have a normal furnace or electric system, leave the switch inthe Standard position.
RefertotheSystemSelectorsectiononthebackformoreinformationonthisswitch.
ŸBesuretotightentheterminalscrewssecurely,otherwisealoosewirecouldcause
operationalproblemswithyoursystemorthermostat.
Ÿ Push excess wires back into the hole to prevent interference when installing the
thermostattothewallplate.
ŸMakesuretheSystemSwitchissettoOFF,andtheFanSwitchissettoAUTO.
Ÿ Insert the bottom tabs on the thermostat body into the slots at the bottom of the
wallplate.Press the topof thethermostatbodytosnap it intothe wallplate.Referto
Figure6.
NOTE: Do not force the thermostat onto the wallplate, as the terminal pins may be
damaged.Ifitdoesnotsnapproperly,thethermostatmaynotwork.
Ÿ Insert the two AA size alkaline batteries, observing the polarity marked inside the
