Functioning
on
domnestic
hot water (
D
HW)
The station can function as
D
HW in both seasons – winter and summer.
The WHW request has priority over the heating request in the „winter” mode.
The station can function as instant
D
HW or as accumulation boiler
D
HW (the boiler is
purchased separately). For the functioning of the station as an accumulation boiler
D
HW
station please contact an authorised service company.
In intant regime, the minimum flow of hot water detected by the station is 2.4 l/min.
For confort in using the station as a D
HW
station we recommend to exploit the station at a flow
of approximately 7-8 l/min.
When the station functions with low flows, the station functions continuously at the minimum
charge as long as the hot water temperature is under the threshold limit of 63°C. When the hot
water temperature reaches the mentioned limit of 63°C, the burner is closed and a new
burning will happen when the hot water temperature is lower than the limit of 60°C
When the station functions with high flows, the hot water temperature will be the opposite of
the hot water flow, but lower than the set temperature.
With instant WHW configuration on request the
CONFORT
function can be activated/
deactivated. Please contact an authorized service company. This function allows the
delivery of hot water as soon as possible, while keeping the boiler hot. If the function is active,
the boiler starts when the hot water temperature is equal to the set hot water temperature;
the boiler stops when the hot water temperature is 8°C ( fixed value) higher than the set hot
water temperature. If the water heated in this way is not consumed within one hour, the
CONFOR
T function is automatically deactivated.
Getting out of this setting mode
is done automatically if no key is pressed for
at least 3 seconds
.
Figures 1.15 and 1.16 are two examples of displaying temperature in the
setting mode.

station is set on winter mode, set value of thermal temperature is 42°C;
Figure 1.16 – – pressure in the heating installation 1,6 bar, central heating
station is set on winter mode, set value of hot water temperature is 60°C.
