Temperature's range limitation

It is possible to limit mechanically the temperature's range (between 10° to 20°C for example) or even to lock the temperature range at a fixed temperature (20°C for example).

For that:

1. Take the two range limiting nibs which are found in the thermostat base.
   
   
2. Locate the knob to indicate a precise value (20°C for example) and remove it.
3. Place the two range limiting nibs.
   
   Ex: to lock the temperature's range at 20°C
4. Put back the knob and check that the temperature's range is limited to the requested values.
