Visu bugs

[gtsamis]

Hi LM team,
Great work on the new visu! It looks much more modern and flexible.

I have noticed a possible issue with the thermostat widget, and I would also like to suggest a few improvements.

Issue: disabled operation modes are still visible
In the widget settings, only Comfort, Stand-by, and Economy are enabled under “Operation modes”. Auto and Building protection are not selected.
However, the widget still displays all operation modes, including the disabled ones. 
         

Suggestions / feature requests

1. Add fan speed control to the thermostat widget.
   
2. Add fan mode selection, for example Auto / Manual.
   
3. Add an output indication for heating/cooling operation, preferably as a percentage value, for example 0–100%.
   
4. It would also be useful if the slider or output indicator could change color depending on the active mode, for example one color for cooling and another for heating.
   
5. Add an error/alert indication icon. This would be very useful in HVAC installations, especially when the heating/cooling output is disabled or reduced due to an open window, or when there is a system error.
   

Most of the above features are almost standard in many KNX room thermostats, so having them available in the widget would make it much more complete and practical for real HVAC installations, especially where fan coil - proportional heating/cooling control is used.
