(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
).
