SWITCHING THE APPLIANCE ON/OFF
Switching on
Switch on the appliance at the master switch (I).
The indicator lamp shows green and the
display will show the central heating flow
temperature, when the appliance is operating
in the central heating mode.
Note: If the display alternates between -II- &
the central heating flow temperature, the
condensate trap filling programme is active. If
the display shows “t” the tank heat up
programme is running.
The condensate trap filling programme ensures
that the condensate trap is filled after the
appliance has been installed or after the appliance
has been out of use for a long period. For that
reason, the appliance remains at minimum heating
output for approximately 15 minutes.
Switching off
Switch off the appliance at the master switch (0).
The green indicator lamp goes out. The
display on the optional timer (if fitted) will
continue to operate until the battery back-up
is exhausted.
SETTING THE CENTRAL HEATING TEMPERATURE

to the desired level:
When the burner is lit, the red indicator lamp is
illuminated.
CONTROLLING CENTRAL HEATING
Set the timer (if fitted) to the correct time.

temperature.
