Press "+" until point "P9" is reached.
Once point"P9" is reached wait for the display to show the flash-
ing indicator "P9" proposing the same settings as point "P0".
Now it is possible to change this value to obtain the maximum op-
erating power desired.
If the gas pressure is insufficient, despite opening the gas servo-
motor to a maximum of 90°, it is necessary to use the gas valve
stabiliser.
After adjusting point "P9" keep the "-" key on the display pressed
for about 5 seconds, "CALC" appears for a few seconds.
P
The control box will automatically calculate the points from "P8"
to "P2", distributing them in a straight line. These are theoretical
and must be checked.
Check that the settings of point "P8" are adequate.
If not, modify the point.
Proceed in sequence, with the "-" button, up to point "P1".
It is possible to modify point "P1" to obtain a minimum modulation
point different to the ignition point ("P0").
Before moving on from one point to the next, wait
for the servomotors to reach the position visual-
ised on the display.
IMPORTANT
During the adjustment of each point, work on the air and gas ser-
vomotors, without modifying the position of the gas valve stabilis-
er.
Halfway through the procedure (i.e. around point P4 or P5), you
are advised to measure gas delivery and check that the output is
about 50% of the maximum output.
If this is not the case, work also on the gas valve stabiliser: in this
case however, it is necessary to revise the calibrations of all the
points previously set.

Backup / Restore procedure
At the end of the "Start-up procedure" it is wise to carry out a
backup, creating a copy of the data memorised on the REC, in
the RDI 21 display panel.
This will allow the data to be used for programming a new REC
or to return to the memorised settings of the same REC.
We suggest that this operation be carried out at
the end of any intervention that involves modifica-
tions to what has been set on the cam.
WARNING
This will allow you to carry out a restore in a simple
manner on a new cam supplied as a replacement
part, without having to reprogramme the system.
6.9.1
Backup
To perform the backup, proceed as follows:
access the Parameters Level referring to "Access procedure
with password" on pag. 39 .
The display screen displays the parameters group 400.

Once the calibration of point "P1" is completed, confirm by press-
ing the keys "+" and "-" (ESC) simultaneously: parameter "546"
will appear.
If you want to make the burner work on the entire modulation
curve, press the "+" and "-" (ESC) keys simultaneously: in this
way, parameter "546" will automatically be assigned the value of
100% and parameter "545" will have a value of 20%.
If you want to make the burner work on just a part of the modula-
tion curve, modify the parameters "546" and "545" according to
the"Parameter modification procedure" on pag. 40.
Press the keys "+" and "-" (ESC) simultaneously twice, the dis-
play will show the current load position.

At the end of the "Start-up procedure" it is nec-
essary to carry out a "Backup", which is used to
memorise the parameters and the data in the con-
WARNING
trol box within the display RDI21...
This operation allows the parameters and the
points of the modulation curve to be restored in
the event of problems.
It is advisable to perform a backup every time that
a parameter is changed!
For the procedure see "Backup" on pag. 43.
