1.
Set the setting button on the middle of the new setting range.
2.
Remove the setting button by pressing gently outwards with a
narrow screwdriver between the button and the cover.
3.
Remove the dial pins and put in the desired holes to limit the
setting range of the thermostat. (Figure 3 et 4)

You can now put the setting button on the thermostat.
