Heating system start-up
Check the heating system pressure on
the pressure gauge (A). The system
pressure is too low if the needle indicates
below 0.8 bar.
Switch ON the mains power supply e.g.
at a separate fuse or a mains electrical
isolator.
Switch ON the ON/OFF switch ( (C);
standby mode is then indicated by the
green indicator (ON indicator); after a
short time the boiler temperature will be
displayed. Your heating system and, if
installed, your remote control unit are
now ready for use.
Note
The circulation pumps are briefly started
every 24 hours for a short time to prevent
pump damage.
