It can take up to 10 minutes to reset the error signal (after resolution). It is advisable to "force" the communication between the probe
and concentrator by briefly pressing the button on the probe; in this way the RF communica-tion between the two devices will be
accelerated and the error signal will be cancelled in a short time.
N.B.: the button on the concentrator is not used under normal conditions. It is considered necessary to indicate to the user not to press it at
any time.
If the button on the concentrator is pressed for 10 consecutive seconds, the concentrator will be "reset to factory data", and the previous
RF associations to probes and BUS to the boiler will be deleted. In these conditions the boiler display signals "E300" and it is necessary to
re-perform the probe association operations (through Service access).
2.7 MAIN SIGNALS THROUGH CONCENTRATOR LEDS
On the concentrator there are two LEDs (1-3) next to the button (2) (Fig. 15). The possible signals on these LEDs are the following.
Status
Normal operation
RF association
N.B.: the absence of any type of flashing is a symptom of anomaly or power failure.
