D.H.W temperature control
The domestic hot water temperature is regulated by
knob
3
(fig.1).
•
Rotating the knob anticlockwise reduces the
temperature.
•
Rotating the knob clockwise increases the
temperature.
•
The range of temperature settings for the
domestic hot water runs from a minimum of 35°C
to a maximum of 60°C.

Topping-up the system with water
The water pressure in the central heating circuit must
be checked during the entire period of operation of
the boiler. In this respect, the reading on the
pressure gauge
M
(fig. 1), located on the lower part
of the boiler, must not be less than 1 bar.
If there is insufficient water in the boiler, led
12
on the control panel will light up (fig 1, page 63) and error code “04”
will flash on the display
13
.
To bring the system back up to pressure, open the external filling loop valve (fig. 1) and use the pressure gauge
M
(fig. 1) to check that the system pressure reaches 1 bar and that led
11
lights up (fig. 1 page 63).
When the operation is complete, close the fill valve.
Diagnostics – Error codes:
This paragraph contains a list of error codes that the boiler may generate on the display
13
(fig. 1 page 63)
together with the relative indications and the operations that the user can carry out to reset the boiler.
If the problem re-occurs after the following actions have been taken, call an authorised Service
Centre.
