Additional-stage heating parameter window

This window is only visible if the Deactivated option has not been selected in the Additional-stage heating
parameter in the Application parameters parameter window.
In actuator mode, this window is deactivated and hidden.
The additional-stage heating of the temperature controller is parameterized in this window. The settings for
the control type, limitation of the control range, the behavior on sending the control value and the limit
temperature are made.
The additional stage is used as a boost for the basic stage. If there are large deviations between the actual
and setpoint temperature, the additional stage is activated to accelerate reaching the setpoint temperature.

Additional-stage heating control value type

Options:
This parameter is used to specify the control and control value type for the additional-stage heating.
The standard value for the parameter is dependent on the selection in the Additional-stage heating and
Actuate additional-stage heating via parameters (Application parameters parameter window).
On the selection of the physical device output for the actuation of the additional-stage heating,
the controller has a fixed pre-configuration that cannot be changed. The pre-configured controller type is
dependent here on the option selected in the Additional-stage heating parameter.
The only exception is on the selection of Free configuration. In this situation, everything can be selected
and set freely.
