A few parameters are used to give the user the desired operation.
A parameter list is used to document the settings of the unit. Be sure to keep this up to date in case the module
must be replaced.
5.2.1 Configuration of the parameters with the built-in display and buttons
To select the function – press MENU first and scroll with PREV and NEXT until the chosen function is
shown. The basic information of the function is displayed, and this can be a parameter value or a measured
value.
Press PLUS to select one of the parameters associated with the selected function. Use PLUS and MINUS to
scroll among the parameters.
Use MENU if you select to go back to the function level.
Press MENU for more than 1 second to return to the basic display indication.
