button for getting the normal operation again.

NB:
every ime the device shuts the burner down (start led switched off - contact 1N-1P open), the manual control is not active.
Device self-setting (auto-tuning):
If the burner in the steady state does not respond properly to heat generator requests, you can activate the Device's self-setting
function, which recalculates PID values for its operation, deciding which are most suitable for the specific kind of request
Display of software version :
The software version is shown by pushing
Enter + UP arrow
on the upper
display
Follow the below instructions:
push the
UP
and
DOWN
arrows for more than 5 s; on the green lower display
TUNE
appears. Now the device pushes the burner to increase and decrease its output. During
this time, the device calculates PID parameters (
Pb1, dt
and
rt
). After the calculations,
the TUNE is automatically deactivated and the device has already stored them.
In order to stop the Auto-tuning function while it works, push again the
UP
and
DOWN
arrows for more than 5 s. The calculated PID parameters can be manually modified
following the previously described instructions.
