Adjustment
Adjust the d.h.w. temperature to a value suited
to your needs.
Reduce the necessity of mixing hot water with
cold water.
In this way, the automatic adjustment features
will be appreciated.
If water hardness is particularly high, we rec-
ommend that the boiler be adjusted to a tem-
perature less than 50°C.
In these cases we recommend however that a
softener is installed on the d.h.w. system.
If the maximum d.h.w. flow rate is too high,
such that does not allow the sufficient tem-
perature to be reached, have a suitable flow
rate limiter installed by the Authorised Service
Engineer.
D.h.w. request
When the boiler has a power request in the
d.h.w. mode, the
symbol is displayed on
the display followed by an increase of the
heating water flow temperature. The
symbol flashes (Fig. 2.26).

disappear from the LCD display
