Can you see a difference between these 2 photos?

No, well let me explain...
The photo on the left is a standard thermostat - it was invented in 1885 over 100 years ago (wikipedia link). The photo on the right is Induni's effort at the same sort of instrument. You will notice there are not many similarities.

- One is easy to read with a digital display / the other has little glass tubes with lines painted on them.
- One works in a standard measure of temperature - degrees Celsius / the other is measured in liters per minute
- One is conveniently located in the rooms where you want to set the temperature / the other is in the basement.


.. I could go on, but I think you get the picture.
