Reference Notes
NOTE 1: Parameters
#
10 thru

16 are accessed from the front panel only,
and can not be set from a remote terminal
NOTE 2: The gain value
(-HG-&-CG-)
is multiplier used to increase the
sen-
sitivity of the controller according
to the
formula: Output
=
Gain (E
+
I
+
D)
where E
=
Error. I
=
Integral. D= Derivative, Its relationship to proportional
band is as follows:
Unit
Span
PROP BAND =
=
Heat Gain (HG) or Cool
Gain
(CG)
Note that proportional band is an inverse function of gain, The range of
18
adjustment is 0 to 400 for Heat. 0 to
400
for Cool.
