11.4.1 Temperature limiter - Temperature limit of additional heating stage
Options:
No
Yes
The parameter is used to activate or deactivate the temperature limit for the basic heating
stage.
Notice
This parameter is only available when the "Control function" parameter is set
either on "Heating with additional stage," or "Heating and cooling with additional
stages".
11.4.1 Temperature limiter - Temperature limit of additional heating stage - Limit temperature
Options:
Setting option between 20 - 100°C
The parameter is used to set the limit temperature for the basic additional heating stage. The
temperature limit becomes active when the input temperatures are above the limit temperature.
11.4.1 Temperature limiter - Temperature limit of additional heating stage - Hysteresis
Options:
Setting option between 0.5 - 5 K
The parameter is used to set the hysteresis for the temperature limit of the additional heating
stage. At an active limit the temperature limit is deactivated again when the input temperatures
are below the limit temperature minus hysteresis.
11.4.1 Temperature limiter - Temperature limit of additional heating stage - 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.
11.4.1 Temperature limiter - Temperature limit of cooling
