Control Of Additional Cooling Stage - Cooling Type; Control Of Additional Cooling Stage - P-Component (X 0.1°C) - ABB i-bus KNX Product Manual

11.5.58 Control of additional cooling stage — Cooling type
Options:
Two cooling types (area or fan coil) with preset parameters are available to the user.
If the required cooling type is not available, individual parameters can be specified in free
configuration.
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".
11.5.59 Control of additional cooling stage — P-component (x 0.1°C)
Options:
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.
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 "Cooling type" parameter must be set on "Free configuration".
