8.5.1 Automatic control mode
The automatic control mode is the normal operating mode used by the controller
to
maintain the actual value of a process variable at the specified setpoint. The
controller evaluates the control deviation and controls the output such that the
actual value of the process approaches the setpoint. Changes to the current set-
point can be made in the controller operation screen or in the "parameteriza-
tion". Two setpoints are stored for each controller in the parameterization.
Setpoint 1 is active by default. Setpoint 2 can be activated instead of Setpoint 1
in each controller by means of "Setpoint selection". Setpoints can also be spec-
ified by external sources and transmitted to the controllers in the JUMO AQUIS
touch S via analog inputs. "Setpoint selection" and the configuration of external
setpoints are set in the "Setpoint configuration".
