I have a central heating system with rads fitted with Caleffi TRVs on each radiator.
The lounge and a couple of bedrooms do not get hot enough as the TRV's cut the rads off even though they are on setting 5.
Is it possible to recalibrate these so they don't cut off at such a low temperature and if so how?
thanks for any help
