Manual mode
▷
For adjustment of the burner control unit or for
fault-finding.
▷
In Manual mode, the BCU operates indepen-
dently of the status of the inputs for start-up
signal (terminal 1), controlled air flow (terminal 2)
and remote reset (terminal 3). The function of the
controller enable/emergency stop input (termi-
nal 46) is retained.
▷
Manual mode is terminated by switching off the
BCU or in the event of a power failure.
▷
Parameter 67 = 0: Manual mode unlimited in
time. The burner control unit may continue to
be operated manually in the event of failure of
the control system or the bus.
▷
