Pre-setting without flame
Setting is carried out in two phases:
- Pre-setting without flame
- Setting the flame, to fine tune the
settings based on the combustion
results
When the burner is switched on, the
screen displays the image below.
Important
At this point, no setting position has
been defined, therefore the burner
cannot be started under these
conditions.
Modify the setting value for a ventilation speed:
- To modify the value of a position, move the cursor to the
corresponding location with the
or
key.
- Select the value to be modified using the
key, the
selected value will flash.

- Confirm the new value using the
key. The value stops
flashing.
Note:
The values for the different speeds can be set freely.
However, for safety reasons, the control unit enforces a
minimum difference of 2° between the different speeds
(except between the ignition position and the 1st stage).
