Use of the sensor with other refrigerants

a full package of new settings have to be uploaded. HB products has the setting files for most refrigerants and you can get
them on request. The refrigerant the sensor is specified for can be found under the basic settings tab. Please note that the list
of refrigerants is not complete and the sensor might be specified for instance for CO2 and can be used for R290 as an exam-
