13.17 - “Installer’s
menu”
CAUTION!!!
Changing these
parameters could cause the
boiler and therefore the system
to malfunction. For this reason,
only a qualifi ed technician who
has in-depth knowledge of the
boiler should change them.
The boiler’s micro-processor makes
this menu of parameters available
to the
qualifi ed technician for the
analysis of the functioning and
adjustment of the appliance to the
system. When entering the “Installers’
Menu”, the display item “1” in Figure
13-1, will start to blink indicating that
a change of mode has taken place. To
access the “Installers’ Menu” just (see
also Section 17 to better understand
the several menus):
1. press and hold the button
down for 12 seconds until the
parameter is displayed;
2. press and release the button
to scroll through the list of the
parameters;
3. once the parameter has been
displayed, it can be changed using
the or keys;
4. press and release the button
to confi rm the amended data before
moving to the next parameter.
When the last parameter has been
reached and the button
pressed, the display will stop blinking
indicating the exit from the menu.
NOTE: If no key is pressed for
more than 60 seconds, the control
automatically exits the “Installers’
menu”. Any parameter change not
saved using the button, will be
lost.
The next table lists each “Installers’
menu” parameter, what it affects and
its adjustment range.
