4.251 Outside temperature source
•
Identification of the current outside temperature source
When interconnecting several controllers, only one outside sensor is required. This
sensor will be connected to any of the controllers and delivers its signal via LPB.
The controllers to which no sensor is connected adopt the outside temperature signal
via the bus system, from a controller to which a sensor is connected.

The first 2 digits represent the segment number (01.)
The second digit corresponds to the device number (.02)
If required (e.g. due to varying exposure to solar radiation of the various buildings), the
different sections of the system can be equipped with their own outside sensors.
