The boiler display
The reading of the boiler display can be done in two
ways.
The Good reading
During this reading the display will only show what
is necessary. Under normal circumstances the
display will give a
Good
reading. If a fault is
detected the boiler will be blocked. This will be
shown with, alternate display of
Good,
with an
E
of Error or a
BL
of Blocking and a number code. For
further information refer to page 13 "Errors,
maintenance and warranty" .
The technical reading
During this reading the display will show in which
operating status the boiler is active. The technical
reading is shown alternately with the water
pressure. The first figure in the technical read out
indicates the status in which the boiler is active and
the third and fourth figure indicate the water
temperature of the boiler. For example in the
reading
P 1.9
the character
P
stands for pressure
which represents the water pressure. The third and
fourth figure indicate the water pressure in bar.
If a fault is found, the same is shown as described
under "The Good reading".

pressure of between 1,5 and 1,7 bar.

remain functioning at a reduced level. After
replenishing the system just above 1,5 bar the
message

function normally again.
When the water pressure drops below 0,7 bar, the
display will show a flashing
FILL

The boiler will shut down and will function normally again
after replenishing the system to just above 1,5 bar.
