12.34.29 Control of heating additional stage – Additional heating type
Options
PI continuous, 0 – 100% and PI
PWM, On/Off:
Options
Fan coil:
Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the control function parameter is set on either
"Heating with additional stage" or "Heating and cooling with additional stages" ,only
available when "Control value type" parameter is set either on "PI continuous, 0 – 100%",
"PI PWM, On/Off" or "Fan coil".
Multiple heating types (panel heating, convector heating or fan coil) with preset
parameters are available to the user. If the required heating type is not available,
individual parameters can be specified in free configuration.
12.34.30 Control of heating additional stage – P-component (x 0.1 °C)
Options
Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the control function parameter is set on either
"Heating with additional stage" or "Heating and cooling with additional stages", only
available when "Control value type" parameter is set either on "PI continuous, 0 – 100%",
"PI PWM, On/Off" or "Fan coil". In addition, the "Heating type" parameter must be set on
"Free configuration".
The P-component refers to the proportional band of a control. It fluctuates around the
setpoint value and can be used to influence control speed with a PI controller. The smaller
the setpoint, the faster it reacts to the control. However, to avoid the risk of an overshoot,
this value should not be set too low. A P-component from 0.1 to 25.5 K can be set.
12.34.31 Control of heating additional stage – I-component (min)
Options
Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the control function parameter is set on either

Convector (e.g. heater) 1.5°C 100 min
Free configuration
Fan coil 4°C 90 min
Free configuration
Input from 10 to 100
Input from 0 to 255
