appears on the display.
Definition of the momentary consumption target value
Definition of the momentary consumption target value is effected in the mode/function momentary consumption:
=> Hold down the key for at least 30 secs., but 32 secs. at the longest
Press the key, after 25 secs. the displayed momentary consumption will flash for 5 secs. As soon as the
flashing stops, release the key. As confirmation the service symbol and the momentary consumption as the
newly defined target value will flash for 5 secs.
For two-stage burners the target value can be separately input in two output stages.
Following a change in burner output (nozzle change, change in pump pressure etc.) the target value, as
specified above, has to be redefined. The old target value is thereby overwritten.
Service function
If the oil flow is reduced by more than 10% (e.g. from a slowly blocking nozzle, preheater etc.), the service
symbol appears on the display unit.
The prerequisite for this service function is previous input of the target value (see Definition of the momen-
tary consumption target value) with correct burner operation.
Deactivation of the service function
Procedure as for definition of the momentary consumption target value, however, hold down the key for lon-
ger than 32 secs. This clears the target value and the service symbol:
=> Hold down the key for at least 32 secs.
Upon being released the service symbol flashes and the zero value on the display flashes for 5 secs. as
confirmation.
