10.1.36 Cooling control - 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".
10.1.37 Cooling control - 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".

10.1.38 Cooling control - I-component (min.)

Options:
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.
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".
