Master controller @@&name@@
Master controller for a cascade sequence control, e.g. for an application as master controller of outlet air temperature. The controller uses information from the start function "@@&ref@@", as this has all the necessary information on the status of the system (e.g. free cooling, dehumidification active, etc.)
The set point of the reference variable can come from a set point function (e.g. room set point) or be parameterised as a constant set point.
If there is no enabling of the control, the set point of the dependent variable is initialised with the set point of the reference variable. After enabling of the control, the master controller works from this point.
If the cooling protection is active, the maximum dependent set point is displayed. With active over-heat protection, the minimum dependent set point is displayed.
