Parameters
7.5.1.9.1 Additional-stage cooling control value type
Options:
This parameter is used to specify the control and control value type for the additional-stage heat-
ing.
The standard value for the parameter is dependent on the selection in the Additional-stage cooling
and Actuate additional-stage cooling via parameters (Application parameters parameter window).
On the selection of one of the physical device outputs 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 cooling parameter.
The only exception is on the selection of Free configuration. In this situation, everything can be se-
lected and set freely.
The following table shows the dependencies:
Option selected:
Additional-stage cooling
Convector (e.g. radiator)
Area (e.g. cooling ceiling)
Electric heater (in room)
