Parasite flame (internal error)
Press and hold down for at least 2 seconds.
385 165
Input voltage too low
Automatic reset at voltages in excess of 175V. If this fault
persists, call the Authorised Service Centre.
431
Exchanger sensor faulty Call the Authorised Service Centre.
In the event of a fault, the display backlighting indicates the error code. 5 reset attempts can be performed after which the
boiler shuts down. Wait 15 minutes before attempting to reset the boiler again.
5. BOILER INFORMATION MENU
Press and hold down for at least 1 second, to display the information indicated in the table. Press to exit.

6. SWITCHING OFF THE BOILER
To turn off the boiler, disconnect the electric power supply using the two-pole switch. In the “Off” operating mode the boiler stays
off but the electrical circuits remain powered and the anti-freeze function remains active.
7. FILLING THE SYSTEM
To fill the system, pull out the telescopic tap “A” at the bottom of the boiler and slowly turn it anti-clockwise (do NOT use tools)
until the pressure, with the system cold, ranges from 1 and 1.5 bar (see pressure gauge “B” - figure to side). After the required
pressure is reached, close the filling tap.
Regularly check that the pressure displayed on the pressure gauge "B" is 1 - 1.5 bar, with the boiler cold. If the pressure is too
low, turn tap "A" to fill the boiler.
If the system pressure is too high, open the drain tap “C” at the bottom of the boiler (figure to side).
A Boiler/system filling tap
B Pressure gauge
C Boiler/system drain tap
Take special care when filling the heating system. In particular, open any
thermostat valves in the system, ensure the water enters slowly in order to
prevent the formation of air inside the primary circuit until operating pressure
is reached. Lastly, vent any radiators in the system. WESTEN declines all liability for
damage deriving from the presence of air bubbles in the primary exchanger due to the
incorrect or imprecise observance of the above.
The boiler is fitted with a hydraulic pressure gauge which prevents the boiler
from working if there is no water.
If pressure drops occur frequently, have the boiler checked by the
AUTHORISED TECHNICAL SERVICE CENTRE.
8. ROUTINE MAINTENANCE INSTRUCTIONS
To keep the boiler efficient and safe, have it checked by the Authorised Service Centre at the end of every operating period.
Careful servicing ensures economical operation of the system.
