NOTE
—
With this wiring, signal A1 from terminal 7 on the board in the ventilation unit is connected
to terminal A on the EIB universal interface 6119/40. Terminal A is configured as an input.
The consequence of this is that only those functions in which terminal A is interpreted as
open can be activated. In this case, this would be the functions with BCD code 0, 2, 4, 6,
8, A, C, E (see BCD encoding in section 8.3.2.1 on page 17).
—
Note which functions are available if the feedback is wired at a terminal other than termi-
nal A.
