SpecialFeatures Description
Opentherm® By connectingtheT3MtoanOpenTherm®appliancevariousspecificdatacanbe viewed.The
dataisdependingonwhattheapplianceisproviding.
Heatrange Thenormallowertemperaturelimitof5°C canbeincreasedupto21°C
toprotecttheinhabitantsfromcold.Usefuliftheinhabitantsincludetheelderly,childrenor
disabled.Thenormaluppertemperaturelimitof37°C
canbereduceddownto21°C tosavethehomeownerenergy.Usefulifthehomeownerrents
totenants.
Scheduleoptions The thermostathasthe7daysbydefault,howeveritcanbechangeto7daysfordifferent
scheduleeachdayoftheweekor1dayforhavingthesamescheduleduringtheweek
Externaltemperature
sensor (onlyforwired
versions)
Anexternaltemperaturesensorcanbefitted,allowingthethermostattocontrolthe
temperaturefromanotherroomorspace,whereitisinconvenienttolocatethethermostat.
Itwillreadtheremotesensorevery1minute.Thesensorcanbeconnectedupto50meters
fromtheunit.Usefulforcommercialpremiseswherethepublicmaytamperwiththeproduct
Optimisation (optimum
start,optimumstopand
delayedstart)
OptimumStart:learnshowlongittakesyoursystemtoreachthetemperatureyouwant.It
turnsontheheatingsystemearliertomakesureit’scomfortableatthescheduledtime.
OptimumStop:Savesenergyandmoneybyswitchingoffalittlebitearlierthanthenormal
programmedtime.Ifthehomeisuptotemperature,itwillnotnoticetheeffectonthe
temperature,butwillshowadifferenceinthefuelbill.
Delayedstart:Savesenergybyslightlydelayingthestartofheatingdependingonthe
differencebetweenthescheduledtemperatureandtheactualroomtemperature.
Clocksetting Changedisplayformat(default24hr)andadjusttimeanddate.
Temperatureoffset IftheThermostatislocatedinahot/coldlocationandcannotbemovedbecauseofwiring
thenthemeasured/displayedtemperaturecanbeadjustedby+/‐ 3°C.Usefulifthe
homeownerwantsthereadingtomatchanotherappliancetemperaturedisplay.
Binding(onlyforT4R) MenutobindtheThermostatandtheReceiverbox,testtheRFsignalstrengthoftheradio
communicationandtoclearanexistingbinding.
Reset Reset thethermostatbacktofactorydefaultsettings,resetthescheduletodefault.
