In addition to the function of control and
safety unit, the control and safety unit BT
3xx also modulates the burner output by
controlling the air flap, gas flap, fuel oil
quantity regulation and frequency
converter (optional) in one electronic
circuit.
The electronic circuit controls the
opening of the gas flap and fuel oil flow
regulation proportional to the air flap
along a curve based on 10 setting points
During start up, the setting points are
defined based on the measurement
values of the combustion gas analysis.
This guarantees optimal combustion
over the burner's entire output
modulation range.
A separate burner ignition load can be
defined with the "Ignition position"
setting point .
The limit values of the control range are
defined by the min. output " " and
max. output " " setting points. In
addition, other optional functions, such
as sealing tests, reventilation or waiting
times can be activated.
