The display shows the current time, the two points separating the time from
the minutes blink with a frequency of 0.5sec ON and 0.5sec OFF, while the
status icons will be active if necessary:
4.26 Replacing SC08 interface
The system configuration operations need to be carried out by professionally
qualified personnel of the Technical Assistance Centre.
When replacing the SC08 interface board, it might happen that when power
up the user is requested to reset the time and the day of the week (see
paragraph "4.6 First commissioning"). Remember that no programming of
the configuration parameters is needed, the values are recovered from the
control and adjustment board in the boiler.
4.27 Replacing the AKM board
When replacing the AKM adjustment and control board it might be necessary
to re-programme the configuration parameters.
