5.2.1 Necessary and optional sensors
Depending on the controller type and the operating mode (single-zone operation / two-zone operation), there
are necessary and optional temperature sensors for the case controller. A sensor scan is performed
automatically during Erstanlauf - Regler auf Werkseinstellungen zurücksetzen of the controller. The number of
scanned sensors can be checked in the menu (6-1) or with the LDSWin PC software. This allows unconnected
sensors to be removed from the monitoring for sensor fault.
The following list shows the necessary and optional temperate sensors for the regulation.
