All parameters can be changed from the control panel. The “
+
” key or the “
–
” key are used to scroll through the parameter list, to
reach the parameter you want to set. Once you have selected the parameter you want, touch the
Standby
key and you will see its
current value. To change the parameter’s value touch the “ + ” or “ – ” keys until you reach the value you want.
To confirm the value touch the Standby key, returning to show the parameter list, to go forward or back to a different parameter to
set it.
After setting the parameters you want, you must reach the last parameter of the “qU” list (touching the “ + ” key until
you get to it), and confirm the completed configuration by touching the Standby key from this parameter, to exit saving all
changes.

Notes:
The parameters that show different values, vary the operating mode (never the range) in relation to the initial FA parameter
(water he-
ater model according to the type of Gas and Litres).
The parameters marked in gray (from P3 to F6) only appear in the real parameter
list if the FA value is between 6 and 15 (that is, for the 15 Litres and 17 Litres models) .
