C183 5-9 CON2 Manual Reset - It determines output valve position when the
controller Loop 3 is in Auto and the error = 0. It is mutually
exclusive with Reset Time.

L162 5-9 CON2 Auto Enable - Output is from the PID algorithm when set to 1
and the A/M push button is in Auto.

C187 5-9 CON2 Controller Span - Enter a value, that when added to the Loop
3 Control Lower Range value, will produce the Control upper
range value in engineering units.
100
C188 5-9 CON2 Controller Lower Range - Enter a value that represents in
engineering units the Loop 3 Control lower range value.

C184 5-9 CON2 Remote Setpoint Bias (B1) - This datapoint and Remote
Setpoint Ratio (K1) allow the CON0

L144 5-9 CON1 Manual Fallback Disable - 0 = always power up Loop 2 in
manual; 1 = Loop 2 auto/manual selector unchanged at
power up.
0
L146 5-9 CON1 Hard Manual Limit - 1 = apply output limits to the final output
of the Loop 2 Auto-Manual Generator. Affects both the
manual push buttons and the controller’s result. 0 = do not
apply limits.

C146 5-9 CON1 Output Low Limit - Sets minimum CON1

OUT signal value in
engineering units.
0
C154 5-9 CON1 Output Slew Rate - It is a rate limit applied to the output
value (setpoint from Loop 2 to Loop 4). When configured to
a non-zero value, the output from the Loop 2 Auto-Selector is
only allowed to change by this amount each scan time. A
zero disables output slewing. It does not affect manual
operation.

C142 5-9 CON1 Proportional Band - Is the percent of error required to move
the CON1

C143 5-9 CON1 Reset Time - Is the number of minutes per repeat of integral
action. It is mutually exclusive with Manual Reset.
