The BCU switches on in the last operating mode 

selected.

 

The heater starts once the set switch-on delay 

time t

 has elapsed, see page 5 (Adjusting the 

switch-on delay tE).

 

The burner starts after the safety time of 5 s has 

elapsed and operates in the selected operating 
mode.

 

The operating mode can be changed using the 

MODE selection button. The selected operating 
mode is only activated once the device has been 
in this position for at least 3 s. It is thus possible 
to “scroll” through the different operating modes.
