CONTROL PANEL ELECTRONIC P.C.B.
LCD FUNCTION
Boiler in chimney sweep in function.
The activation of the chimney sweep oc-
curs configuring the "parameter P09=01"
and is visualized:
LP = minimum D.H.W.
hP = minimum heating
cP = maximum heating
dP = maximum D.H.W..
The transition occurs with keys A (in-
crease) and B (decrease) C.H. tempera-
ture.
The writing on the display alternates.
7 .3 Info modality
The INFO mode allows the display of some information on the
boiler functioning status. In case of malfunctioning of the boiler,
it may be useful to communicate such information to the Author-
ised Service Centre Engineer so that the causes can be under-
stood.
In order to access the INFO mode, press keys A and C (Figure
7.1) at the same time until the letter di appears on the display that
alternates with a code (Figure 7.1).

To scroll the values press B (reduce) and A (increase). keys (Fig-
ure 7.1). In order to exit the INFO mode, hold keys A and C (Fig-
ure 7.1) pressed at the same time. The following table gives de-
tails of each parameter and the possible value that can be show.
