ILLEGAL DATA
On the other hand, some combinations are programming errors because they are wrong settings; in this case the error
code is ILLEGAL_DATA. This information is accessible to ModBus reading the register 7.
NO ERROR
CH_1 Trip ≤ Alarm
CH_4 Trip ≤ Alarm
FAN_1 ON ≤ OFF 0 FAN INT ≤ 10
FAN_2 ON ≤ OFF
Value HFN > max see table: SYSTEM - Setting and Status
Value FCD > max see table: SYSTEM - Setting and Status
Value 4.20 > max see table: SYSTEM - Setting and Status
Value Voting > max see table: SYSTEM - Setting and Status
Note. If the value of Voting is higher than the max value expected for the model in question, it will be set equal to "0", that is
NO_VOTING.
