The factory setting was chosen to allow for direct connection of the digital outputs
to the digital inputs of the Synco™200 controller.
As the Synco™ 200 controllers do not know operating mode Precomfort, the
central control unit RMB795B switches the Synco™ 200 controllers directly to
Comfort in the event of Precomfort. This setting can be changed to suit individual
needs.
When the digital outputs "Relays 1 /2" of a "Room group" function block are
connected to the room operating inputs of 1 or several other "Room group" function
blocks, the following assignments for the "Relays 1 /2" outputs are to be made:
Operating line Assignment
