 Withoutroomregulatorandbuffer(Fire‐upfunction):
TheCHboilerisdampedwhenthepre‐setDHWtemperatureisreached.EmergencyCHboilerdampingwill
becarriedoutwhenthepre‐setCHtemperatureisexceededby5°C.
 RoomregulatorON,withoutbuffer(Fire‐upfunction+Roomregulator):
Roomregulator does notinfluenceCH boiler operation.TheCHboilerisdampedwhenthe pre‐set DHW
temperatureisreached.EmergencyCHboilerdampingwillbecarriedoutwhenthepre‐setCHtemperature
isexceededby5°C.
 BufferON(Fire‐upfunction+Buffer+DHWfunctionfrombuffer):
Whenthepre‐settemperatureofbufferbottomisreached(C2sensor), CH boiler damping will start
regardless of CH and DHW temperature. The main screen displays ‘Buffer pre‐set temperature reached’
belowFire‐up/Dampingtouchbuttons.Emergencydampingwillalsostartwhenthepre‐setCHtemperature
isexceededby5°C.

 IfthecontrollerisequippedwithadditionalGSMmodule,itisnecessarytoactivateitbyselectingON.
GSMModuleisanoptionaldevicewhich,cooperatingwiththecontroller,enablestheuserremotecontrolofthe
CHboileroperationviamobilephone.TheuserissentanSMSeachtimeanalarmoccurs.Moreover,aftersendinga
certaintextmessage,theuserreceivesfeedbackonthecurrenttemperatureofallthesensors.Remotechangeofthe
presettemperaturesisalsopossibleafterenteringtheauthorisationcode.
GSM Module may operate independently of the CH boiler controller. It has two additional inputs with
temperaturesensors,onecontactinputtobeusedinanyconfiguration(detectingclosing/openingofcontacts)andone
controlledoutput(e.g.apossibilityofconnectinganadditionalcontractortocontrolanyelectriccircuit)
Whenanyofthetemperaturesensorsreachesthepre‐setmaximumorminimumtemperature,themodule
automaticallysendsanSMSmessagewithsuchinformation.Asimilarprocedureisusedinthecaseofopeningor
closingofthecontactinput,whichmaybeusedasasimplemeansofpropertyprotection.
If ST‐912 controller is equipped with GSM module, it should be activated by selecting ON option (MENU>Fitter's
