1st stage adjustment
If the flame has been detected and stabilised, the control and safety unit switches the burner to
the 1st stage.
- Depending on the required output, set the fuel oil pressure to 1st stage using regulator
8
on the
pump. Monitor the combustion values continuously as you do so (CO, CO
2
, soot).
If necessary, adjust the dimension
Y
and/or adapt the airflow.
- To do this, modify the 1st stage ventilation speed. Proceed as described on page 16 in the
paragraph
"Modifying the value of a servomotor position setting"
.
- Warning: when modifying the setting value, the speed changes in real time. Therefore, the
combustion values must be constantly checked.
Special function: ignition checking
If the ignition speed has been modified, it is possible to carry out a new burner start-up to check
the new ignition speed, without having to exit the settings menu.
To do this, after modifying the ignition speed, position the cursor on the
symbol, and initiate
the new start-up using the
key.
Setting the opening position of the 2nd stage fuel oil valve
After the 1st stage is set, it is possible to set the opening value for the 2nd stage fuel oil valve.
Proceed once more as described in the paragraph
"Modifying the value of
a speed setting"
.
- Warning: in this case the speed does not change immediately, but first remains in the 1st stage
position (the actual speed is always displayed in the lower part of the display). The 2nd stage
solenoid valve also remains closed. It is first possible to modify the 2nd stage speed.
Adjustment for stage 2
To set the 2nd stage speed, position the cursor on the corresponding line on the display using the
key. If necessary, modify the setting value. Proceed as described in the paragraph
"Modifying
the value of a speed setting"
.
- To make the burner actually switch to the 2nd stage, press the
key again. The speed
reaches the set position. At the same time, the 2nd stage fuel oil valve will open, as soon as
the set speed for the fan motor is exceeded.
- Depending on the required output, set the fuel oil pressure to stage 2 using regulator
9
on the
pump. Monitor the combustion values continuously as you do so (CO, CO
2
, soot). If necessary,
adjust the dimension
Y
and/or adapt the airflow.
- To do this, modify the 2nd stage speed. Proceed as described on page 16 in the paragraph
"Modifying the value of a speed setting"
.
- Warning: when modifying the setting value, the speed changes in real time. Therefore, the
combustion values must be constantly checked.
Special function: positioning the opening and closing of the 2nd stage fuel oil valve
differently
The control unit makes it possible to set the opening of the 2nd stage valve, when switching from
the 1st stage to the 2nd stage, at a different position to that for closing when the 2nd stage drops
back to the 1st stage.
- To do this, as described earlier, first set the opening position of the 2nd stage oil valve.
- Lastly, position the cursor on the
symbol and confirm with the
key. The selected symbol
will then appear like this
.
- Using the
key, position the cursor on the setting value for the 2nd stage fuel oil valve, and
set the new closure position, as described in the paragraph
"Modifying the value of a speed
setting"
.
