Air pressure switch failure:
If the fan and the pump is running but the boiler doesn’t light, check the air pressure switch.
Blown fuse:
If the main switch is on and display does not light check the FUSE 1 (T1.6A), see diagram 23.
The pump, the fan and the ignition module don’t work.
Warning message:
If the pressure in CH system drops to 0.8 bar the LED on the Bar button starts to flash. This give you
information that CH pressure is on the low limit and must be pressurised. Nevertheless the boiler works until
the pressure drops to 0.6 bar – then boiler shuts down and F0 is displayed.
DHW flow is poor
If DHW floor is poor or boiler does not start when hot water tap is open, check following:
Cold water supply pressure is at least 1 bar.
Check if the cold water filter or flow regulator (plastic “O” ring) is not clogged.
Check free movement of the magnetic shunt (mounted inside cold water filter).
Note: The Hall Effect Sensor is
polarity sensitive , consequently the magnet must be kept in the exact
position. Before completely dismantling the Flow Detector, print a mark on the visible face of the magnet, in
order to reassemble it with the
right polarity .
