Operating Modes
ThesearethepossibleoperatingmodesoftheSC2311L.
Off Mode
Inoffmode,thethermostatwillnotturnontheheatingorcoolingappliances.
Note 2: The indoor fan can be activated in every mode by sliding the Auto/On fan to the On
position.
Note 2: Off mode in used to enter the conguration setup (by pressing LEFT and RIGHT
simultaneously for 5 seconds).
Cool Mode
Incoolmode,thethermostatcontrolsthecoolingsystem.
Thereisafourminutetimedelayafterthecompressorturnsoff.Thisprotectsthecompressor.
Heat Mode
Inheatmode,thethermostatcontrolstheheatingsystem.
Forheatpumps,thereisafourminutetimedelayafterthecompressorturnsoff.Thisprotectsthe
compressor.
Emergency Heat Mode(Heatpumpsystemsonly)
Inemergencyheatmode,theheatpumpsystemwillbedisabledandauxiliaryheatwillbecomethe
primarysourceofheat.
ENTER Emergencyheatmodebypressingtheupbuttonfortensecondswhileinheatmode.“EH”
willthendisplayonthescreen.
EXIT Emergencyheatmodebypressingtheupbuttonfortenseconds.“EH”willnotdisplayon
thescreenwhenyouexitemergencyheatmode.
TheSC2311LalsoexitsemergencyheatmodewhenthemodeswitchismovedtoCool.
Thisfeatureisusedfortransferringthecongurationsettingsfromthemastertothetarget
thermostat.Allthermostatsforajobcanbemountedandpoweredup.Congureonethermostat.This
willbethemaster.Themasterwillbeusedtocopythecongurationtotherestofthethermostats.
Preparing the master to Send:
1.Themastermustbepoweredby24VAC.
2.VerifythemasterthermostatisinOFFmode.Slidesystemswitchtocenter
position.
3.Removecoverofthemasterthermostatbygentlypullingnearoneofthecorners
atthetopofthethermostat.
4.PresstheupanddownbuttonsandLEFTswitchsimultaneouslyfor5seconds.
5.TheOUTscreendisplaysindicatingthemasterthermostatisreadyto
transferdata.
Note: Press the up and down buttons and LEFT switch simultaneously for 5
seconds to exit from data transfer mode and to return the master to the
OFF mode.
6.Connectthemastertothetargetusingthe3wireconnector.Attachoneendto
theMaster’sFPpinsandtheotherendtotheTarget’sFPpins.
Note: Target thermostat must be powered by 24 VAC for eld programming
to occur.
Whentheconnectionhasbeenmadecorrectly,themasterthermostatwillpower
upandthetargetwillcountfrom6downto1.ItwillthendisplayLOCconrming
thedatahasbeensavedinmemory.
Whenalltargetthermostatshavebeencompleted,reinstallthemasterthermostat.
PresstheupanddownbuttonsandtheLEFTswitchsimultaneouslyfor5secondstoexit
fromthedatatransfermodeandtoreturnthemasterthermostattotheOFFmode.

Starting the Thermostat
RoomTemperature
CAUTION! : Do not use air conditioning when the outdoor temperature is below 50 degrees.
This can damage your air conditioning system and cause personal injuries.
1.MovetheFan Auto/OnswitchtotheAutoposition.
2.MovetheCool/Off/HeatswitchtoCoolorHeat,dependingontheseason.
Mode of Operation
TheSC2311Lisatwo-stageheat,one-stagecoolthermostat.Itfunctionswithairconditioning,heat
pumps,gas,oilorelectricheat.
Thethermostatactivatestherststageheatwhentheroomtemperatureisbelowtheheatset
temperature(bythedifferentialtemperature).Secondstageheatwillbeactivatediftheroom
temperaturecontinuestodrop.Theheatoutputsarestagedoffastheroomtemperatureincreases.
Forheatpumpsystems,thethermostatwillnotletthecompressorcomeonforfourminutesafterit
turnsoff.Thisprotectsyourcompressor.
Whentheroomtemperatureisgreaterthanthecoolsettemperature(bythedifferentialtemperature),
thecoolingdeviceisactivated.Thecooloutputisturnedoffastheroomtemperaturedrops.The
thermostatwillnotletthecompressorcomeonforfourminutesafteritturnsoff.Thisprotectsyour
compressor.
TheSC2311Lhasthefollowingoperatingmodes:OFF,Heat,EmergencyHeat,andCool.InOFF
mode,thethermostatwillnotturnonheatingorcoolingdevices.IntheHeatmode,thethermostat
controlstheheatingsystem.Forheatpumpsystems,EmergencyHeatmodeisusedtobypass
thecompressor(onlybackupheatoperates).IntheCoolmode,thethermostatcontrolsthecooling
system.TheindoorfancanbeturnedoninalloperatingmodesusingtheFanswitch.

3. SlideFanswitchtoAutoposition.
4. Indoorfanturnsoff.
Oncethethermostatisinstalled,itshouldbethoroughlytested.
CAUTION!:
Do not energize the air conditioning system when the outdoor temperature is
below 50 degrees. It can result in equipment damage or personal injury.
Testing the Thermostat
Cool Test
1. SlideModeswitchtoCoolmode.
2. Adjustsettemperaturesoitis5degreesbelowroomtemperature.
3. Airconditioningshouldcomeonwithinafewseconds.
4. Adjustthesettemperature2degreesabovetheroomtemperatureandtheA/Cshouldturnoff.
Theremaybeafandelayonyoursystem.
Note: There is a four minute time delay to protect the compressor after it turns off. To
temporarily bypass the four minute delay, slide the Mode switch to OFF for 2 seconds
and then back to Cool.
