For the UA 412 S, the first five sensor inputs must be populated with NTC sensors and the last five
sensor inputs with Pt1000 sensors. Further details for this can be found in the section
.
The following list shows the necessary and optional temperate sensors for the regulation.

Error message in the event of sensor fault
An alarm (sensor fault) is triggered if necessary sensors are not attached. If optional sensors are not attached,
this alarm only occurs if these sensors have been incorporated in a sensor scan. A sensor scan can be
initiated in menu 6-1.
In the case of optional sensors that are not included in a sensor scan, no actual values are archived
in the system centre / store computer.
5.3 Description of the controller function
The various functions of the case controller are described below. The presence of specific controller functions
depends on which controller type has been set at the DIP switch S3 (see chapter
Setting of the controller type
).
