The controller can be integrated into a data network using an optional RS-485 (terminals R+ and R-) interface or an optional Profibus
DP interface(only modelRWF55.6x terminalsC1-C2-C3-C4)
(bold = factory settings)
Manual control :
In order to manual change the burner load, while firing keep pushing the ESC button for more than 5 s; on the lower green display
Hand appears.
using the UP and DOWN arrows, the load varies.
Keep pushing the ESC button for getting the normal operation again.
NB: every time 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 fun-
ction, which recalculates PID values for its operation, deciding which are most suitable for the specific kind of request
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.
