• At the end of the
Fh
cycle, the winter mode screen will appear on the display (fig. 11), make
the temperature adjustments: heating flow and DHW outlet (fig. 14 and fig. 15). Check if the
value of flue parameter,
P68

for the length of flue installed.
• In case of a gas change (G20 - G30 - G31 - G230), check if the relevant parameter is suitable
for the type of gas used in the supply system ( and cap. 3.1 "Adjustments" on page 319).
