NOTE

NOTE: if the control action type is changed, the control

parameter values (P, I, D) are updated with values
calculated by the last TUNE function (first part of SMART
algorithm).
If these values are wrong, they are not updated and the
E.120 error is displayed (for details see "Error messages"
at pag. 83).
When run time is activated, it will be necessary to enable
a new TUNE procedure.
