how will it go off their is nothing to tell the boiler the room is up to temp.
as long as the heatings on it will keep cycling on the boiler stat.
trv's on rads only close the rad when up to temp not shut the boiler off.

the boiler should have interlock which is a room stat so that the room temp tells the boiler to shut down when up to the stat temp say 21 degrees.

your boiler will never shut down with out one.
and it is also a building reg that it has a room stat.
