8.2 Controller “Cntr”
Cntr: Controller
The following are set here: controller type, input variables of the controller, the setpoint
limits, conditions for manual mode and the presettings for autotuning (self-
optimization).

Inverse
inverse:
The controller output Y is > 0 when the process value is
smaller than the setpoint (e. g. heating).
direct:
The controller output Y is > 0 when the process value is larger
than the setpoint (e. g. cooling).

inhibited
If the manual mode is inhibited, changing over to “manual” is
not possible from the keys or via the binary input.
Manual output
HAnd
-100…101 Defines the controller output level after changing over to
manual mode.
101 = last output
For modulating controller:
101 = actuator is stationary;
0 = actuator closes; 100 = actuator opens
Range output
rOut
-100…0…101 Output on over/underrange.
101 = last output
For modulating controller:
101 = actuator is stationary;
0 = actuator closes; 100 = actuator opens
Setpoint low
SPL
-1999…+9999 Setpoint limiting prevents the input of values outside the
defined range.
Setpoint high
SPH
-1999…+9999
Factory settings are shown bold.
H
The setpoint limits are not effective with setpoint input
via the interface.
The correction value is limited for external setpoint with
correction.
