7.2.0.1 Procedure for inserting and adjusting points on
the modulation curve
Nine adjustment/calibration points (P1 ÷ P9) can be inserted in
the flame control for each servomotor, varying their position by
degrees and, consequently, the quantity of air and fuel intro-
duced.
The ignition point P0 is independent of the minimum modulation
value. This means that, in the event of difficulty, it is possible to
switch on the burner at a value other than the modulation mini-
mum (P1).
To access the Parameter mode (group 400) referring to the "Ac-
cess procedure with password" on page 36.
To insert or adjust a point, proceed as follows.
Using the keys "+" and "-" insert/select the curve point you want
and wait for it to flash: this means that the servomotors are now
