6.3 DOMESTIC HOT WATER OPERATION

To select the DHW function push the press 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
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
The DHW setting can be varied between 20 and 55°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

The symbol H appears after the 85 value or before the 8 value. If this value is selected, the heating will function in anti-freeze
mode.
If the setting is higher than the actual temperature of the heating water and external control
demands heat, the heating will connect and a small red indicator of the consumption of heating
resistances will light up.
6.5 ANTI-FREEZE MODE (Frost Protection)
It is possible to select an anti-freeze mode for frost protection during periods of inactivity. The power supply to the boiler
must be maintained.
By attempting to set a central heating temperature below the 8ºC value or above the 85ºC value the symbol H will appear on
the display. By selecting this value, the heating will only work in anti-freeze mode i.e. if the boiler temperature falls to 7ºC the
heating will activate automatically.
