9.2 Control strategies and setpoints for
controller 1, basic type A
9.2.1 Selecting the control strategy
Controller 1 in basic type A is used for temperature control.
Different control strategies are available.
The following table shows the dependencies:

1 Any input Xx of the input block can be used.
Selection of an input identifier label requires that the respective temperature is indeed acquired
(e.g. ROOM: (Room temperature must be available)
2 The "connection" is made as a setting value in controller 1 block
3 Setting value STRATGY has no impact in connection with room temperature and supply air
temperature control.In these cases, the setting value is not evaluated
4 CAS/CON facilitates changeover from cascade control in the summer to supply air temperature
control in the winter (when heating is ON) via a digital input
5 If both input identifiers SAT and ROOM are available, the STANDBY setting decides whether
room-supply air temperature cascade control or room temperature control with supply air
temperature limitation is performed
6 If selection of a control strategy is required and none is selected ("---")
- applies to room-supply air temperature cascade control and room temperature control with
supply air temperature limitation – control strategy "Supply air temperature control"
is automatically activated
