- Protection degree of rear panel on terminal board side: IP20
- Display with light segments
- Visualisation of max temperature and the relevant channel in the automatic mode
- Alerts of pre-alarm, alarm, probes fault, fanning, manual function, historic highs
- System programming directly by frontal panel
- Possibility to select independently each channel
- Limit of alarm and pre-alarm settable in the range (-9°C ÷ 199°C)
- Precision ± 1% on full-scale ± 1 digit
- Cooling fan control on three or four channels
- Comparison of temperature for cooling fan between two different levels (L and H).
- Four selectable operating modes
- Detection of fault probes, maximum flexibility of managing and simplicity of programming, checking of validity of the insert data during programming phase
