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.

Fig. 4

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.
