7 Errors and faults
7.1 Detecting errors and rectifying faults
The electronic control unit recognises and saves errors. They are
displayed by an error message on the display:
– Backlit in red (see also chap. 3.2.1)
– Error code (see tab. 7-3).
An integrated error protocol saves up to 15 of the last error mes-
sages that occurred.
Depending on the operating mode, the error messages are also
forwarded to connected room controllers or room thermostats.
7.1.1 Current error display
7.1.2 Reading the error protocol
The error protocol can be read at the "Special Level" (see
fig. 7-2).
Here, the latest (most recent) error message received is given top
priority. All other previous error messages are then pushed down
by one place by each new entry. The 16th error message is de
-
leted if a new error message arrives.
CAUTION!
Electrostatic charges can lead to voltage arcing
that can destroy the electronic components.
Ensure potential equalisation prior to touching
the switching panel PCB (e.g. by touching the
switching panel holder).
1 Error code (see chap. 7.3)
