Replenishing or complete filling up of the installation
The installation functions at an optimum water pressure of between
1,5 and 2 bar. If the step key is pushed briefly, the water pressure can
be shown. After this the waterpressure
is shown. When the
step key (
) is pushed again briefly one will return to the
reading.
When the water pressure drops below 1 bar the display will
automatically show the text
. This text is being
interchanged with the normal display reading
.
During this display reading the boiler will only function at a reduced
output. When the water pressure is sufficiently high again (above 1,5
bar) the
text will disappear and the boiler will return to the
normal act. If the water pressure drops further and comes below 0,7
bar the display will show a flashing
text. After this the boiler will
switch off and will only function again when the waterpressure comes
above 1,5 bar.
Turning the boiler off
Holiday period: Adjust the Brain thermostat to the holiday
period. See the thermostat manual for this
