11.8.48 Basic stage cooling — Maximum control value (0 - 255)
Options:
Setting option between 0 - 255
The maximum control value of the PI controller defines the maximum value outputted by the
controller. If a maximum value under 255 is chosen, the value will not be exceeded, even if the
controller calculates a higher control value.
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".
11.8.49 Basic stage cooling — Minimum control value for basic load (0 to 255)
Options:
Setting option between 0 - 255
The minimum control value of the PI controller defines the minimum value issued by the
controller. If a minimum value that is greater than zero is selected, the controller will not issue a
lower value, even if it calculates a control value that is lower. This parameter can be used to set
a basic load, e.g. for operating surface cooling. Even if the controller calculates the control value
zero, a cooling medium will flow through the cooling area to prevent the floor from heating up.
Under "Settings of basic load," it is also possible to define whether this basic load will be
permanently active or whether it will be switched by the "Basic load" object.
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".
