Rom stats are important in that they're your main comfort control ... TRV;s are then individual room temp controls when the heating is on 🙂 Look at how you can section off (zone) your home for heating needs .... bedroom first thing and last thing is different to living area during the day! That's zoning spycatcher. You can have as many zones as you like to be honest! A trv is a kind of seporate zoning device ... 🙂
