■D.H.W. temperature control
The domestic hot water temperature is regulated by knob
3 (see “Control panel”).
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. 2), located on the lower part of the boiler, must not be
less than 1 bar.
If there is insufficient water in the boiler, the code H2O will flash on the display (see fig 2).
To bring the system back up to pressure, open the external filling tap R (fig. 2) and use the pressure gauge M(fig.
2) to check that the system pressure reaches 1 bar and that the code H2O lights up.
Diagnostics – Error codes:
This paragraph contains a list of error codes that the boiler may generate on the display 8 (see “Control panel”)
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.
_E01_ Ionisation block
Code E01 lit continuously on the display.
Check that the gas valve on the boiler and gas meter are open and that there is gas in the mains supply (or in
the tank).
Switch off then switch on the appliance using switch 1(see “Control panel”) on the control panel.
When the error code on the display disappears, the boiler will restart.
If the problem persists, Call the Service Centre.
_E02_ Safety Thermostat tripped
Code E02 lit continuously on the display. Call the Service Centre.
_h2o_Water Pressure Switch tripped
Code H2O lit continuously on the display.
Check the water pressure in the central heating circuit. The reading on the pressure gauge M(see fig. 2),
located on the lower part of the boiler, must not be less than 1 bar .
If the pressure is less than 1 bar, top-up the system as described in paragraph “Filling the system”.
The boiler will restart automatically.
If the problem persists, Call the Service Centre.
_E05_ Heating Sensor malfunction
Code E05 lit continuously on the display. Call the Service Centre.
