3.3 Setting the main operating parameters
The plug-in series instruments are supplied ready to use. They are in fact programmed in the factory (default settings) to respond to
the more common requirements. The programming is performed by assigning all the parameters the more frequently required
value; the table below lists the parameters and the corresponding default value.

(**) unit of measure (hereafter u. of m. in the tables).
To achieve the maximum performance from the controls, or in the case of special needs, the values of the operating parameters can
be modified. The following notes describe the factory settings and the parameters which are more frequently modified (set point,
differential, etc.). Furthermore, for convenience, all parameters which should be checked before operating the unit are indicated.
