Stop
The error codes are displayed in the info row of the remote panel and
also remain if the fault was temporary.
Therefore, you must always reset to eliminate the "Allarm" from the
display.
Check operation of the fan (18) and the connections
Check that the fan has minimum head of 60 Pa.
Press the release key, if the fault persists, replace the board
Correction: if the line voltage < 190Vac: the line's voltage is way below the mini-
mum limit, otherwise line errors of the monitor: replace BMM
(BCM)
The ignition procedure is prevented until the gas pressure has reached the correct
values.
Try to Reset for the system to automatically activate the antifreeze function and
thus may only be a warning.
Circulation control, check installation (Only with return probe installed).

Check Chimneys / Check Drain Trap.
Check the combustion chamber / check the drain trap.

Check electrical connections e-BUS1
Check electrical connections BMM e-BUS1
Connect a new sensor if the code disappears, replace the sensor or check the
electrical connections
