14) NOTES FOR REMOTE PROGRAMMING
Also in the remote programming phase via ModBus you must take into consideration that
the Alarm thresholds must be lower than the Trip thresholds, and that Fan-ON-thresholds
must be higher than the Fan-OFF-thresholds as well as the Pump-ON thresholds must be
higher than Pump-OFF thresholds.
After a writing request, the unit will be busy for about 1" to memorize the data in eeprom;
during the memorizing phase (led TX NTxxx ON), the MULTIMODULE will not be able to
accept other requests.
15) ERROR CODES (exception code)
In case of a wrong request MULTIMODULE will answer with modified codes and codified
codes according to the following points:
1: - Non-supported error code
2: - Wrong data address
3: - Wrong data (for instance length)
16) POLLING FREQUENCY
The maximum time to give an answer to a calling never exceeds 1 second; therefore we
suggest not to use polling frequencies with lower duration.
