The factory setting has been chosen such that the digital outputs can be connected
directly to the digital inputs of the Synco™200 controller.
Since the Synco™200 controllers do not use the Precomfort mode, an automatic
change from Precomfort to Comfort mode will be made. This setting can be changed to
suit individual needs.
The adjustable values previously listed under "Settings" have the following meaning:
Value set
