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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3°Fabove
theroomtemperature.
Result:Theheatingsystem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.
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.
