2.2.16. FAULT SIGNALLING CODES
The fault signalling codes are displayed only on the display of the master control panel.
Except for the faults common for both units (as for example: E04, E78, E06, E99), the fault signalling code
will be displayed with the prefix ‘01’ or ‘02’, which indicates that in that unit, there is a fault (01 = main
master unit, 02 = secondary slave unit).
If there is a fault in both units, the display shows only the most serious signalling code. In order to view
the next signalling code, press the ‘
’ key of the ‘S’
symbol. After restoring the first fault, the display
will show the next alternating signalling code of the temperature of the collector. In order to manually
reset the unit, press the RESET ‘
’ key when the display shows the signalling code.
To view the last 5 fault signalling codes chronologically, starting with the most recent one, activate the
‘OFF’ mode by pressing the FUNCTION ‘
’ key and hold the key INFO ‘
’ for 5 seconds. Use keys ‘
’ and ‘
’ of the heating circuit
to scroll through the list of saved faults. To reset the fault history
press the RESET ‘
’ key. To exit display mode press the INFO ‘
’ key.
When a signalling code represents a fault common to both units (such as for example: E04, E78, E06, E99)
it will be preceded by the message E(x)‘, where ‘(x)’ will be the chronologically order number in the last
5 signallings.
