Parameter Description
RESET (Integral Time) - adjusts
the controller's output according
to both the size of the deviation
(SP-PV) and the time it lasts.
The amount of corrective action
depends on the value of Gain.
The reset adjustment is
measured as how many times
proportional action is repeated
per minute(Repeats/minute) or
how many minutes before one
repeat of the proportional action
occurs(Minutes/repeat).
RATE action, in minutes affects
the controller's output whenever
the deviation is changing; and
affects it more when the
deviation is changing faster.
Applies Gain to the feedforward
value (FFV). Feedforward Input
is multiplied by this value.
MANUAL RESET- is only
applicable if you do not use
RESET (Integral Time)
Allows correction of output to
account for load changes to
bring the PV up to setpoint.
