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

TherearethreeLEDindicatorslocatedonthefrontofthethermostat.Theyaredesignedtoinformyouofthefollowing:
AUX (GREEN): Thisturnsonwhentheauxiliary(back-up)heatingisinoperation.Thisisthesecond(non-economy)
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.
