3.2 Switching the Appliance On/Off
Switching on
B 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 oper-
ating in the central heating mode.
The trap filling programme ensures that the condensation 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 appli-
ance remains at minimum heating output for 15 minutes.
Switching off
B Switch off the appliance at the master switch (0).
The green indicator lamp goes out. The optional timer will con-
tinue running until the emergency supply is exhausted.
i
If the display alternates between -II- and the cen-
tral heating flow temperature, the trap filling pro-
gramme is active.
