When the procedure ends, it switches off the control output
and sets the value 4 in word 1004. The master, which keeps
reading the word 1004, checks the various zones and when all
of them have reached the value 4 it will bring to 0 the value
of word 1004.
The various devices will regulate the temperature based on
the new values.
N.B. The master must read the Word 1004 at least every 10

autotuning procedure.

1. The first selection (write 1 in word 2028) allows to modify,
through the word 1005, the functioning mode: after
writing 1 it is possible to change the output percentage on
word 1011 (range 0-10000).
To return to automatic mode, write 0 on word 1005.
2. The second selection (write 2 in word 2028) enables the
same mode, but with two important variants:

the manual functioning will be maintained as well as the
previously set output percentage value.
t *G UIF TFOTPS CSFBLT EVSJOH BVUPNBUJD GVODUJPOJOH UIF
controller swithes to manual mode while maintaining the
output percentage control unchanged as generated by
the PID immediately before the break.
