Remote Sensor Installation (Optional) Setting the Temperature Differential
Thedefaulttemperaturedifferentialis1°.Whenyourroomtemperaturevariesby1°F,thethermostat
turnsonyoursystem.Ifyounoticeyoursystemturningonandofftoofrequently,increasethe
temperaturedifferential.
1.Resetthethermostatbyremovingbatteriesfor10secondsandthenreinstallthem.
2.Fortherst10secondsofoperation,thetemperaturedifferentialisdisplayed.
3.Pressthedownorupbuttontoselectdesiredsetting.
Starting the Thermostat
1.MovetheFan Auto/OnswitchintotheAutoposition.
2.MovetheOff/HeatswitchintotheHeatposition.
A Quick Test
Donotshortjumperacrossterminalsonthegasvalveoratthesystemcontroltotestinstallation.
Action: SettheOff/HeatswitchtoHeat;pressthe
up buttonuntilthesettemperatureis5°Fabovethe
roomtemperature.
Result:Heatingsystemandfanshouldturnon;theremaybeatimedelaydependingonyour
system.
Action:
Pressthedownbutton untilthesettemperatureisbelowtheroomtemperature.
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theabovetest was unsuccessful,doublecheckthatthewiresaresecurelyconnectedandare
connectedtotheproperterminals.Consultthetroubleshootingsectionbelow.
