Autotuning – only with controller function
If the device is operated as a two-state controller, autotuning can be started and stopped either manually
on the device, or via a digital signal (positive edge).
Manually starting autotuning:
1. Press and hold "Up" and "Down" simultaneously (>3 s).
a) The 2nd display shows "AUTOTUNING".
Autotuning has started.
Manually cancelling autotuning:
1. Press and hold "Up" and "Down" simultaneously (>3 s).
a) The display returns to the basic status.
Autotuning has ended.
NOTE!
If the controller is switched to manual mode or the actual value goes into "Out of Range", the device can-
cels the autotuning process. When autotuning is cancelled, the device retains the set parameters.
Optional settings:
•
Deactivating optimization of the cycle time by entering a parameter.
•
Locking the autotuning function in the configuration.
•
Configuring the controller output type that is to be optimized via a parameter.

Manual mode – only for controller function
Manual mode is only possible if the device is operated in the controller function. After the changeover to
manual mode, either the current output level or a specific, adjustable output level is displayed and output
(configurable).
During manual mode, "MANUAL MODE" flashes in the 2nd display, alternating with the manual output
level. The "Up" and "Down" buttons can be used to change the output level.
With the corresponding configuration (Configuration > Display/Operation), the "Back" key can be used
to switch to manual mode.
Manual mode can be generally inhibited in the configuration. It is also possible to change over to manual
mode, and also to inhibit manual mode, through a digital signal.
