Important Safety Information
General Description
TheSimpleComfort®2201isintendedtooperateandiscompatiblewith24VACresidentialheatpumpswithupto
2-stageheat/2-stagecool.Itwilloperatewithmulti-stageheatpumpsystemsthataremanualchangeoverandhave
auxiliaryoremergencyheating.Therearenooptionalitemsrequiredforstandardinstallations.Thisthermostatisalso
compatibleasamasterthermostatinzonedsystemapplications.
TheSimpleComfort®2201willautomaticallycontroltheheatand/orairconditioningsystem.Whenusedproperly,this
thermostatcanreduceheatingandcoolingcoststhroughouttheyear.
• Alwaysturnoffpoweratthemainpowersourcebyunscrewingfuseorswitchingcircuitbreakertotheoffposition
beforeinstalling,removing,cleaning,orservicingthisthermostat
• Readalloftheinformationinthismanualbeforeinstallingthisthermostat
• Thisthermostatshouldbeinstalledonlybyaprofessionalcontractor
• Thisisa24VAClow-voltagethermostat;donotinstallonvoltageshigherthan30VAC

stageofheat.Itturnson2degreesbelowrststageandisnotadjustable.
CHECK (RED): Whenthisturnson,amalfunctionhasoccurredsomewhereintheheatpumpsystem.Pleasecontact
aqualiedservicetechnicianassoonaspossibletocheckyoursystem.
EMER (RED):This light turns on whenever the emergency heat is manually selected (system switch is in
the EMER position). While in the emergency heat mode, the heat pump compressor is off,
and the emergency heat (same as the auxiliary heat) maintains the setpoint temperature.

Setting a New Temperature Differential
IMPORTANT: Thedefaulttemperaturedifferentialisfactorysetat1°F.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accordingly.
Step 1: RemovecoverandpressResetbuttononce.
Step 2: Thedisplaywillshow
Thisisthetemperaturedifferentialsetting.
Step 3: Pressthe or buttontoadjustthetemperaturedifferentialdownorup.
Thedisplaywillreturntotheroomtemperaturedisplayveseconds
afterthelastinput.Thenewtemperaturedifferentialsettingwillbe

Step 1: Removethecover.
Step 2: MovetheF/C jumpertothedesiredposition,ForCusingthecenterpinasacommon.
Step 3: PresstheReset buttononceandreinstallthecover.
YourLCDreadoutchangesaccordingly.
Starting the Thermostat
Step 1: MovetheFan switchintotheAutoposition.
•InAuto,indoorfanrunsonlyduringaheatingorcoolingcycle
•InON,indoorfanrunscontinuously
Step 2: MovetheMode switchineitherCoolorHeatposition,dependingontheseason.
Thethermostatwillnowoperateandmaintaintheroomtemperatureatthedesired
setpoint.
Note: Whenthethermostatoperatesthesystem,thereisbuilt-incompressor
protection.Afterthecompressorturnsoff,thesystemwillnotturnitback
