11.5.26  Basic stage heating — 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". 
 
11.5.27  Basic stage heating — 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 output by the 
controller. If a minimum value greater than zero is chosen, the controller will not output a lower 
value, even if it calculates a value that is lower. This parameter can be used to set a basic load, 
e.g. for operating floor heating. Even if the controller calculates the control value zero, a heating 
medium will flow through the floor heating system to prevent the floor from cooling down. 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".
