Some parameters in the moducontrol board must
be set appropriately on the basis of the type of
system in which the unit is installed.
These modifications, performed by the installer, are
summarised and organised in the following guided
procedures, with which to correctly set the unit
circuit board parameters.
29.1. HOW TO MODIFY A PARAMETER IN
To enter the USER presses shown in , once
you press the key you must enter your password to
access the various menus;
to change the value of the password using the ar-
row keys . Once the correct password, press
