* Device default setting, which corresponds to the use of temperature probe NTC
code VN870200 (see "Red line" in catalogue under the section Thermoregulation
- temperature probes)
** When using sensors other than "type 4" as noted above (see note *), it is possible
to select one of the three items "nt0, nt1, Cst" corresponding to probes with
different temperature/resistance ratios. In these cases, in order to identify the
type of sensor to be selected, we recommend contacting the Technical Assistance
Service Department directly.
