NOTE
This parameter is only available when using pressure to
temperature feedback conversion.
If the choice Linear [0] is selected in par. 20-01 Feedback
1 Conversion, then the setting of any choice in
par. 20-02 Feedback 1 Source Unit does not matter as
conversion will be one-to-one.

Enter the desired minimum value for
the remote reference when operating
with par. 1-00 Configuration Mode set
for Closed Loop [3] operation. Units are
set in par. 20-12 Reference/Feedback
Unit.
Minimum feedback will be -200% of
either the value set in
par. 20-13 Minimum Reference/Feedb. or
in par. 20-14 Maximum Reference/
Feedb., which ever numeric value is the
highest.
