3.10 PROGRAMMING THE P.C.B.
The water heater is set up for possible programming
of several operation parameters. By modifying these
parameters as described below, the system can be
adapted according to specific needs.
To access the programming phase, press the
"MENU" button (2) until the "Password" menu
appears. Enter the password, modify the numer-
ical values using the "central heating regulation"
buttons (5) and confirm with the "OK" button (1).
Once you have accessed programming, you can
scroll through the parameters in the "System"
menu.
Using the "central heating regulation" button,
select the parameter and edit the value.
To save the parameter change, press the "OK"
button.
Wait for 1 minute or press the "ESC" button (3)
to exit programming mode.
