How many TRV's Can I have on my system

I currently have 10 radiators all fitted with a Smart TRV.

I have now had to install another radiator in our utility room. Is it possible to add another smart valve as I've heard that only 10 can be fitted to the system

    @Boomba the 10 limit refers to the number if rooms which can directly call for heat from the boiler.

    Example, you can have 25 devices, split across 15+ rooms but you need to specify which 10 rooms can directly call for the boiler.

    The remaining 5 rooms will get heat when the boiler is on (called by one of the 10 specified room) and the room TRV is calling.
