PRACTICAL TIPS
-If the water is very hard, it is recommended that a water softener be added to the system so as to reduce the formation of limescale in the boiler exchangers. This will ensure that the efficiency of the unit remains the same over time, reducing gas consumption and maintenance costs.
-If the boiler should be out of use for a prolonged period, it is recommended that the electrical power supply be disconnected and that the external gas cock be closed. If low temperatures are expected, the boiler and system pipe work should be drained in order to prevent frost damage.
-To improve comfort and take full advantage of the heat produced by the boiler, it is
recommended that an external (room) thermostat be installed.
-It is good practice to clean and service the appliance and central heating system every year. Call an Authorised Service Centre.
IGNITION PROCEDURE
Turn the selector knob “A” to the “I” position. The display will | A | I | |
indicate “on” indicating that the boiler is ready to operate. The | |||
| |||
electronic control unit will ignite the burner, without any manual |
|
| |
intervention but in response to the request for Domestic Hot Water |
|
| |
or heating. If, after approximately 10 seconds, the burner has not |
|
| |
ignited, the boiler safety devices will shut off the gas and the | PL004D |
| |
display will indicate the fault code A01. To reset the ignition |
|
system, the reset button “D” must be pressed and released. Should |
| |
the boiler fail to ignite a second time, check that the external gas cock | D | |
is open. If the problem persists, contact an Authorised Service Centre. | ||

WINTER AND SUMMER OPERATING MODES
In the ‘winter’ operating mode, the boiler will produce both Central Heating and Domestic Hot Water. In the ‘summer’ operating mode, the boiler will produce only Domestic Hot Water.
Using the knobs on the control panel, the user can select ‘winter’ or ‘summer’ operating mode.
Keeping the knob “C” at the “
” position selects the ‘summer’ operating mode, the simbol “ “ will illuminate. ‘Winter’ operating mode may be selected by positioning the knob “C” between the
min. and max. settings. The simbol “ | “ will illuminate. |

ADJUSTING THE HEATING
It is possible to set the temperature of the Central Heating system by adjusting the knob “C”. By positioning the indicator somewhere between min. and max., a temperature may be obtained which varies from approximately 45˚C to about 80˚C.
The water temperature in the primary circuit may be checked on the display.
EXTERNAL (ROOM) THERMOSTAT CONTROL
If an external (room) thermostat is installed, it is recommended that the temperature of the Central Heating system be set by means of the “C” knob, leaving it at max in order to obtain the best performance from the boiler and to allow the regulation of the external temperature to function efficiently.
SETTING THE HOT WATER FOR DOMESTIC USE
Both in the winter and summer mode, the temperature of the Domestic Hot Water may be adjusted by using the “B” knob. A delivery temperature for the water may be chosen in a range from 36˚C to about 56˚C, depending on the flow rate of the water and the position of the knob between the min. and max. settings.
The water temperature in the primary circuit may be checked on the display.
