10.2 Errors acknowledgement
CAUTION! Risk of property damage!
Only acknowledge errors after they have been
resolved.
• Errors may be resolved by qualified
technicians only.
• When in doubt, contact the manufacturer.

played instead of the status
• To acknowledge a error, proceed as
follows.
• Press the rotary knob.
• The following information appears in the display:
• Menu number <6.0.0.0>.
• Malfunction number and maximum number
during the 24 hours of the error occurrence (e.g.
1/6).
• The time remaining until the error is reset auto-
matically in seconds.
• Wait for the auto reset time to elapse.
A timer runs inside the system. The remaining
time (in seconds) until the error is automatically
acknowledged is displayed.
• When the maximum number of error is reached
and the last follow-up time has elapsed, press
the rotary knob to acknowledge.
The system returns to the status page.
NOTICE: If time for the resolution of the mal-
function remains after the error signal
(e.g.: 300 s), then the error must always be
acknowledged manually.
The auto reset timer is inactive and "­ ­ ­"
is displayed.
