ST – 460 operation manualIV.e.2) Pellet boiler firing-upThis option is used for setting voltage-free signal to fire-up the pelletboiler. The user sets the activation delta (the difference between the settemperature and the current tank temperature), below which the controllersends the signal to ignite the boiler. Then, a time interval is selected inwhich this function will be active (by means of the "From hour..." and"Through hour..." functions). The last step is to mark whether the boilerfiring up signal will be shorted contact (icon marked) or open contact.TANKSENSORCOLLECTORSENSORCollectorsensorAddit ionaldev iceNO COMTanksensorPump 2Va lveAdditionalsensor1Pum p 1Additionalsensor2Pow erFu se3,15ARSTOP BOTTOMPowerFree voltagecontact~Pum pIV.e.3) HeaterThe heater's function is to heat the tank electrically. The principle ofoperation is similar to that in the previous case, however, the heatershould be connected by means of an additional contactor.
