SECTION 6 – OPERATION
If you press the REMOTE button, the setting charac-
teristics of the remote set point are determined based
on the setting base temperature and the remote setting
differential. The actual target temperature is calculated
depending on these settings and the remote Set Point
setting signal (4-20 mADC).
This calculated temperature is shown in Set Point as
the present target temperature. If remote set point set-
ting signal (4-20 mADC) is out of its range when you
press the REMOTE button, the Recording Sensor
Abnormal Alarm button lights. The target tempera-
ture changes to the Local setting.
If a failure occurs, you automatically see the Failure
Alarm screen.
