Teaching the Transmitters

Repeating Incorrect Teaching Processes
If the teaching process failed, the central vacuum
unit‘s LCD display reads “LN01“ for 1 second, followed
by “FAIL“ for 3 seconds.
These two messages can repeat themselves up to 10
times.
1. Wait until the central vacuum unit‘s LCD display
alternately reads “FFB“ and “OPEN“.
2. Repeat the transmitter teaching process (see above).
Make sure the approx. 1 m gap as well as the repeti-
tion time of 60 seconds are not exceeded.
1. Hold the handle of the suction hose or the manual
transmitter against the central vacuum unit (refer to
Fig. 4).
2. Press either the ON or OFF button.
The LCD display on the central vacuum unit displays
the term, “LERN“ (“TEACH“ in English).
3. Move the handle/transmitter approx. 1 m away from
the central vacuum unit and press once again either
the ON or OFF button within 60 seconds.
The LCD display on the central vacuum unit then
changes to „LN01“ for 1 second.
If the teaching step was successful, the display then
reads “OK“ for 3 seconds after “LN01“ goes off.
4. Wait until the “OK“ display goes off.
The transmitter has now been successfully taught
and the central vacuum unit can be started with the
ON button.
