6. Setthermostatbaseandcoverawayfromworkingarea.
7. Usinga3/16”drillbit,drillholesintheplacesyouhavemarkedformounting.
8. Useahammertotapsuppliedanchorsintomountingholes.
9. Alignthermostatbasewithmountingholesandfeedthecontrolwiresthroughwireopening.
10. Usesuppliedscrewstomountthermostatbasetowall.

CAUTION! : Besureexposedportionofwiresdoesnottouchotherwires.
11. Tightenscrewsonterminalblock.Gentlytugwiretobesureofproperconnection.Doublecheckthateachwire
isconnectedtotheproperterminal.
12. Setthefan jumpertoelectricorgas/oil,andheatpumpjumpertoNON-HPorHP.
13. Replacecoveronthermostatbysnappingitinplace.
14. Turnonpowertothesystematthemainservicepanel.

A Quick Test
 CAUTION! : Donotswitchsystemtocoolifthetemperatureisbelow50°F(10°C).Thiscandamagethe
airconditioningsystemandmaycausepersonalinjury.
Do not short jumper across terminals on the gas valve or at the system control to test installation.
Action: SettheCool/Off/HeatswitchtoCool.Pressthedownbuttonuntilthetemperature
settingis3°Fbelowtheroomtemperature.
Result:TheA/Csystemandfanshouldturnon.
Action: SettheCool/Off/HeatswitchtoOff.
Result:TheA/Cshouldturnoff(Theremaybeafandelay).
Action: SettheCool/Off/HeatswitchtoHeat.Presstheupbuttonuntilthetemperature
settingis3°Fabovetheroomtemperature.
Result: Theheatingsystemandfanshouldturnon(Theremaybeatimedelaydependingonyour
system).
Action: SettheCool/Off/HeatswitchtoOff.
Result:Theheatingsystemshouldturnoff(Theremaybeafandelay).
Action: SettheFan Auto/OnswitchtoOn.
Result:Theblowerfanshouldturnon.
Action: SettheFan Auto/OnswitchtoAuto.
Result:Theblowerfanshouldturnoff.
Iftheabovetestwassuccessful,youhaveaproperinstallation.
If not:
Doublecheckthatwiresaresecurelyconnectedandareconnectedtotheproperterminals.Consultthe
troubleshootingsection.
Operation
Setting the Room Temperature (Setpoint Temperature)
Step 1: Pressoneofthearrowbuttons;thecurrenttemperaturesettingdisplays.
Step 2: Pressthedownoruporuparrowbuttonuntilthedesiredtemperaturesettingdisplays.
Thenewtemperaturesettingisautomaticallysaved.After5seconds,thedisplayreturnstoshowingthecurrent
roomtemperature.
Setting a New Temperature Differential
Thedefaulttemperaturedifferentialis1°.Whenyourroomtemperaturevariesby1°F,thethermostatturnsyour
systemon.Ifyounoticeyoursystemturningonandofftoofrequently,increasethetemperaturedifferential.
Step 1: ResetthermostatbypressingtheResetbuttononce.
Step 2: Fortherst10secondsofoperation,thetemperaturedifferentialisdisplayed.
Pressthedownoruparrowbuttontoselectdesiredsetting.
Starting the Thermostat
Step 1: MovetheFan Auto/OnswitchintotheAutoposition.
Step 2: MovetheCool/Off/HeatswitchtoCoolorHeat,dependingontheseason.
