Hi its not wired wrong as far as i can tell.
Firstly the boiler is supposed to switch on and off independent of the room thermostat this is quite normal.
Do the radiators stay hot when the heating is on.
If they do then then its more likely that the radiator is to small to heat the room with the thermostat in
you could try turning the boiler thermostat higher if you haven't already done so.
If they are cooling down or not getting very hot you could have a problem with the boiler thermostat or a circulation problem.
