Description of application and parametersApplication "RTC"Product manual 2CKA001473B9679 │10211.4.29 Additional heating stageNoteOnly available when the "Extended settings" parameter under "Control ofadditional heating stage" is set on "Yes".11.4.30 Additional heating stage — Mode of the control valueOptions: NormalInverseThe mode of the control value can be used to adapt the control value to de-energised opened(normal) or de-energised closed (inverse) valves.– Normal: Value 0 means "Valve closed".– Inverse: Value 0 means "Valve open".11.4.31 Additional heating stage — Hysteresis (x 0.1°C)Options: Setting option between 3 - 255The hysteresis of the two-point controller specifies the fluctuation range of the controller aroundthe setpoint value. The lower switching point is located at "Setpoint value minus hysteresis" andthe upper point is at "Setpoint value plus hysteresis".NoteThis parameter is only available when the "Control value type" parameter is seteither on "2-point 1 Bit, Off/On" or "2-point 1 Byte, 0/100%".11.4.32 Additional heating stage — Control value difference for sending of heating controlvalueOptions: 2 %5 %10 %Send cyclic onlyThe control values of the 0 - 100% PI continuous controller are not transmitted after everycalculation. Instead, they are transmitted when the calculation results in a value that is differentenough to the previous sent value to make a transmission meaningful. This value difference canbe entered here.NoteThis parameter is only available when "Control value type" parameter is seteither on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or "Fan coil".
