Device Status Indication

If a critical error occurs, all Modbus values are set to NaN (according to IEEE754 for data type FLOAT32) or to
0x8000 (INT16). It is possible to read out all status and error information via Modbus register 609 (0x260). Errors
are displayed in bit-coded form. If an event is present, the corresponding bit is set to 1.
Measured values outside the measureing range are limited with the corresponding limit value.
Error Bits Description
Bit 0 RH sensor shortcut
Bit 1 RH sensor broken
Bit 2 T sensor shortcut
Bit 3 T sensor broken
Bit 4 PT1000 sensor shortcut (T17 and T28 only)
Bit 5 PT1000 sensor broken (T17 and T28 only)
Bit 6 Tube heater failure
Bit 7 RH sensor contamination (little bit)
Bit 8 RH sensor contamination (dirty)
Bit 9 RH sensor contamination (very dirty)
Bit 10 Parallel capacity misconfiguration
