Radiator thermostat

Hello when I put all my radiator thermostats on 2 they stay cold. They heat up on higher numbers but I want them on 2. Why does this happen please?

Although you think the dials or numbers relate to settings they arn't, they are actually temperatures(however not displayed). So if your thermostat won't heat at level 2 it means the actual room temperature is higher than that of level 2 on your thermostat and therefore wont come on.

*=8°C , I=12°C , II=16°C, III=20°C, IV=24°C , That's Danfoss, other makes will be slightly different , I guess.
