Replenishing or complete filling up of the installation
The installation functions at an optimum water pressure of between 1 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
or
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
. The Brain thermostat will show the text “Waterpressure too low - no disorder - fill water”.
Through out this 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. The Brain thermostat will show the text “Waterpressure too low - disorder - fill water”. After this the boiler is
switched 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 operation. When there is no Brain
