7If [enter] is pressed, at.ON remains steadily lit and AT begins.
During AT, the rightmost decimal point flashes twice repeat-
edly.
When AT is done, the light goes off and the new PID values
go into effect.
During the AT process, if the mode is changed to READY or MANUAL, if PV
input is faulty, or if a power failure occurs, AT stops automatically without
changing the PID values.
AT can also be stopped by changing the setting from At.ON to At.OF (return
to step 4 above).
Setup of SP value
1Press [display] re-
peatedly so that the
orange SP indicator
lights up on the lower

numerical value cannot be
changed to a value above
the limit. The SP limit must
be changed first.
4If [enter] is pressed,
the displayed value
is set and the display
changes from flashing
to continuously lit.
If the [display] key is
pressed without pressing
[enter] key, the status re-
turns to that of step 1.

on the lower display
flashes, and can be
changed.
Press [<], [ ] or [ ], and
change to the desired
value for event set
value. In this case, the
flashing of the numeri-
cal value implies that it
is not yet set.
6If [enter] is pressed,
the changed numeri-
cal value is set and
changes from flashing
to continuously lit.
Similarly, use e2 to set a value for event 2, and e3 to set a value
for event 3.
7To continue from this
point and set hyster-
esis as well, press [ ]
twice or [ ] repeatedly
to get E1.HY on the
upper display. The
lower display says 5.
5on the lower display
indicates that the event
hysteresis is "5".
8In the same way that
event settings were
changed, press [enter]
to make the number
flash, and then press
[<], [ ] or [ ] to change
to the desired setting
for hysteresis. After
that, press [enter] to
finalize the setting.
