Important Safety Information
WARNING! : Alwaysturnoffpoweratthemainpowersupplybeforeinstalling,cleaning,orremovingthermostat.
• Thisthermostatisfor24VACapplicationsonly;donotuseonvoltagesover30VAC.
• Donotshortacrossterminalsofgasvalveorsystemcontroltotestoperation;thiswilldamageyourthermostatandvoidyour
warranty.
• Allwiringmustconformtolocalandnationalelectricalandbuildingcodes.
• Donotuseairconditioningwhentheoutdoortemperatureisbelow50degrees;thiscandamageyourA/Csystemandcause
personalinjuries.
• Usethisthermostatonlyasdescribedinthismanual.
To Remove Existing Thermostat
ELECTRICALSHOCKHAZARD –Turnoffpoweratthemainservicepanelbyremovingthefuseorswitching
theappropriatecircuitbreakertoOFFpositionbeforeremovingtheexistingthermostat.
1. Turnoffpowertoheating&coolingsystembyremovingthefuseorswitchingtheappropriatecircuitbreakeroff.
2. Removecoverofoldthermostat;thisshouldexposethewires.
3. Labeltheexistingwireswiththeenclosedwirelabelsbeforeremovingwires.
4. Afterlabelingwires,removewiresfromwireterminals.
5. Removeexistingthermostatbasefromwall.
6. Refertothefollowingsectionforinstructionsonhowtoinstallthisthermostat.
Battery Installation and Information
Two“AA”alkalinebatteriesareusedtopowerthethermostat.Theyareinstalledintothebackofthethermostat.
Orienttheminthecorrectdirectionasshownontheplasticthermostatcase.
Thebatteriesshouldbechangedyearlytopreventleakagefromdamagingthethermostatandvoidingyour
warranty.
Ifthebatteriesarenotchangedthethermostatwilleventuallydisplay andconserveenergybymaintaininga
lowersetpointinheatingandahighersetpointincooling.

To Install Thermostat
ELECTRICALSHOCKHAZARD –Turnoffpoweratthemainservicepanelbyremovingthefuseorswitching
theappropriatecircuitbreakertoOFFpositionbeforeremovingtheexistingthermostat.
IMPORTANT:Thermostat installation must conform to local and national building and electrical codes and ordinances.
Note:Mount the thermostat about ve feet above the oor. Do not mount the thermostat on an outside wall, in direct
sunlight, behind a door, or in an area affected by a vent or duct.
 1. Turnoffpowertoheating&coolingsystembyremovingthefuseorswitchingtheappropriatecircuitbreakeroff.
 2. Putthermostatsubbaseagainstthewallwhereyouplantomountit(besurewireswillfeedthroughthewireopeningin
thesubbaseofthethermostat).
 3. Marktheplacementofthemountingholes.
 4. Setthermostatsubbaseandthermostatawayfromworkingarea.
 5. Usinga3/16”drillbit,drillholesintheplacesyouhavemarkedformounting.
 6. Useahammertotapsuppliedanchorsinmountingholes.
 7. Usesuppliedscrewstomountthermostatsubbasetowall(makesurethermostatwireisthroughhole).
 8. Insertstripped,labeledwiresinmatchingwireterminals.Tightenscrewstosecurewires.
 
CAUTION! :Be sure exposed portion of wires does not touch other wires.
 9. Gentlytugwiretobesureofproperconnection.Doublecheckthateachwireisconnectedtotheproperterminal.
10. Install2“AA”batteriesintobackofthermostat.
11. Snapthermostatontothesubbase.
12. Turnonpowertothesystematthemainservicepanel.
13. Congurethermostattomatchthetypeofsystemyouhave.

2-stagecool(dependingonyourmodel)thermostat.Itfunctionswithairconditioning,heatpumps,gas,oil,orelectricheat
systems.Anoutdoorsensorcanbeusedtomonitortheambienttemperature.Asecondremotesensormaybeusedtomonitor
thetemperatureinanotherarea.Thethermostatactivatestheheatingappliancewhentheroomtemperatureisbelowtheset
heattemperature(bythedifferentialtemperature).Whenthecallforheathasbeensatised,theoutputsareturnedoff.With
heatpumps,thethermostatwillnotletthecompressorcomeonfor4minutesafteritturnsofftoprotectyourcompressor.
