Note: This parameter is 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.
12.34.18 Control heating – I-component (min)
Options
Note: This parameter is 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 I-component refers to the reset time of a control. The integral component has the
effect of moving the room temperature slowly toward, and ultimately reaching, the setpoint
value. Depending on the type of system used, the reset time has to have different values.
In general, the more inactive the overall system, the greater the reset time.
12.34.19 Control heating – Extended setting
Options
This parameter enables additional functions and communication objects, e.g. "Basic
stage heating".
12.34.20 Basic stage heating – heating status object
Options
Note: Only available when the "Extended settings" parameter under "Heating
control" is set on "Yes".
This parameter enables the "Status heating" communication object.
