Description of application and parametersApplication "RTC"Product manual 2CKA001473B9679 │11211.4.52 Control of additional cooling stage — Cooling typeOptions: PI continuous, 0 – 100% and PI PWM, On/Off:■ Area (e.g. cooling ceiling) 5°C 240 min■ Free configurationFan coil:■ Fan coil 4°C 90 min■ Free configurationTwo 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 freeconfiguration.NoteThis parameter is only available when "Control value type" parameter is seteither on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or "Fan coil".11.4.53 Control of additional cooling stage — P-component (x 0.1°C)Options: Setting option between 10 - 100The P-component refers to the proportional band of a control. It fluctuates around the setpointvalue 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 shouldnot be set too low. A P-component from 0.1 to 25.5 K can be set.NoteThis parameter is only available when "Control value type" parameter is seteither on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or "Fan coil". In addition,the "Cooling type" parameter must be set on "Free configuration".
