The outside temperature can be delivered by different sources:
•
Locally connected to a terminal
•
Delivered via bus
The following variants are available:

The outside temperature signal can be transmitted to other controllers via bus or it can
be received by the bus. For that purpose, communication must be activated and an
outside temperature zone must be set. An outside temperature zone identified by “---”
means that the outside temperature on the bus is inactive.
To enable different outside temperature signals to be transmitted via bus (e.g. outside
temperature for heating zone North, outside temperature for heating zone South), they
must be assigned to own outside temperature zones. The relevant settings are de-
scribed in chapter 14 „Communication“.
