Water pressure in the central heating system
The installation will function optimally with a water
pressure of between 1,5 and 1,7 bar.
If the water pressure drops below 1 bar, the display
will show FILL . During this message the boiler
will remain functioning at a reduced level. After
replenishing the system just above 1,5 bar the
message FILL will disappear and the boiler will
function normally again.
When the water pressure drops below 0,7 bar, the
display will show a flashing FILL text.
The boiler will shut down and will function normally
again after replenishing the system to just above
1,5 bar.
To retreive the water pressure on the display from
the Good reading:
- Press the Step key once briefly.
The water pressure will be shown.
Press the Step key briefly to return to the Good
reading .
