Service menu
ONLY FERROLI TRAINED PERSONNEL CAN ACCESS THE SERVICE MENU AND MODIFY PARAMETERS.
The PCB Service Menu is accessed by pressing the Reset button for 10 seconds.
The display will show: "100" and the message "co" flashing.
Then set "103" with the DHW buttons, with the heating buttons set "123" and confirm by pressing the Reset button.
Five submenus are available: press the Heating buttons to select increasing or decreasing order,
“tS”, “sC”, “In”, “Hi”
or
“rE”
.
To enter the selected menu, press the
reset
button once.
“tS” - Engineers Parameters Menu
Press the Heating buttons to scroll the list of parameters in increasing or decreasing order. Press the DHW buttons to
view or modify the value of a parameter: the change will be automatically saved.
