No always on radiator on unvented system

Had a new boiler and some new rads installed just over a month ago. This was setup as an unvented system. I also had a Honeywell Evohome installed for zoned heating. I don’t appear to have a radiator with no trv that is always on. Is this unusual?

No, you will probably have a bypass installed. It will look something like this. https://www.screwfix.com/p/honeywell-straight-auto-bypass-valve-22mm/34127?kpid=34127&ds_rl=1249799&ds_rl=1245250&ds_rl=1249481&gclid=EAIaIQobChMIt6HOw_ao2AIVpLDtCh0dOwc8EAQYBSABEgK_rfD_BwE&gclsrc=aw.ds&dclid=CMPDoMn2qNgCFVM-GwodHbsJnA Look for it somewhere on the pipework connecting the flow and return.
If not ask the installer about it.0 -
Or it may be internal to the boiler...
