To select the DHW function push the press the
button.
Pushing again will switch the function off and return display to
just a red dot.
When the DHW mode is selected the display will show the actual temperature in the DHW accumulation tank. The boiler
will always give priority to DHW production over central heating until the selected DHW temperature is reached.
If heat is demanded by the DHW and the elements are energized a small red indicator is displayed to the right of the
temperature display.
This light will go out when the desired temperature is reached.
The setting of the DHW temperature can be modified by pushing either the
button or the
button and using the
same buttons to adjust the setting that flashes on the display. The modified setting will be stored automatically after a few
seconds, or instantly by pushing the
button.
The DHW setting can be varied between 20 and 60°C. When Eco Smart is activated, the set-point temperature is reduced
during the non-use periods and the word ECO alternates with the DHW setting during the temperature configuration. See
"6.12 ECO SMART FUNCTION".
The DHW has priority over the central heating operation and so the outputs are never added together.
Water storage at maximum temperature will provide the best protection against the possible formation of legionella
bacteria.
