CONFIGURATION PARAMETERS AND DEFAULT VALUES SUMMARIZING TABLE
Operator Menu configuration parameters - User Menu configuration parameters
• the symbol (4) indicates that the unit of measure depends from the parameter /bE (the parameter /bE belongs to the User Menu; see the
chapter User Menu on the page 32): if the condensing probe is a 2 wires 4-20 mA pressure transducer the unit of measure depends from the
parameters /5P, /b6 and /b7 (the parameters /5P, /b6 and /b7 belong to the User Menu; see the chapter User Menu on the page 32), if the
condensing probe is a PTC probe the unit of measure depends from the parameter / t (the parameter / t belongs to the User Menu; see the
chapter User Menu on the page 32)
• the symbol (5) indicates that during the status ON the parameter is available both to the first and to the second level.
