Description of application and parameters
Application "RTC"

The parameter is used to activate or deactivate the temperature limit for the basic cooling stage.
Notice
This parameter is only available when the "Control function" parameter is set
either on "Cooling," "Cooling with additional stage," "Heating and cooling" or
"Heating and cooling with additional stages".
11.4.1 Temperature limiter - Temperature limit of cooling - Limit temperature
Options:
Setting option between 20 - 100°C
The parameter is used to set the limit temperature for the basic cooling stage. The temperature
limit becomes active when the input temperatures are above the limit temperature.
11.4.1 Temperature limiter - Temperature limit of cooling - Hysteresis
Options:
Setting option between 0.5 - 5 K
The parameter is used to set the hysteresis for the temperature limit of the basic cooling stage.
At an active limit the temperature limit is deactivated again when the input temperatures are
above the limit temperature plus hysteresis.
11.4.1 Temperature limiter - Temperature limit of cooling - Integral component of the PI
controller
Options:
Keep
Reset
The parameter is used to define the processing of the I-component of a PI controller for
temperature limiting.
If the I-component is retained, this value is the starting point for continuing the PI controller after
the termination of the temperature limit. This option is suitable for slow control systems.
If the I-component is reset, the PI controller starts after the termination of the temperature limit
with an I-component of zero. This option is suitable for fast control systems.
If no PI controller is used, this parameter is without function.
