By default, a device is in the automatic mode and switched as described in
the above table.
However, at any time, this logic can be overruled by manual input. This
device is then no longer in automatic mode, indicated by a >> leading the
device name.
By pressing the rotary button on the display unit, then hovering over the
appropriate device, the softkeys change their functions to manually turn
off, turn on or revert to automatic switching of the device. Pressing the
rotary button again exits that menu.
The control unit always memorizes the state of a device. So if for an
example the system is shut down manually, then turned on again, the
same devices are immediately powered/have the same state as at the
time of shutdown (within 1-4 seconds) while the display unit takes longer
to boot up. (20s or so).
The system permanently monitors the pins for short circuits and over
current conditions. If a device faults, it is automatically switched off,
marked red, an alert triggered and the device automatically selected,
showing details.
The fault status can be manually reset.
