This bit is always 0 in actuator mode.
0: No override

Bit 5: Security Mode
The device is in the Security mode, e.g. due to temperature value or control value failure, a predefined control value
(Cyclical monitoring parameter, page
When in controller mode, the device is also in Security Mode after booting up, because the controller has not yet received
a valid temperature value.
This does not depend on whether cyclic monitoring was activated for the temperature.
The device is operating normally when the group object value is 0 (= all individual bits = 0).
