TRV temperature setting vs room temperature

Hi All, I am planning to buy a full Tado system but I wonder if the TRV is measuring the temperature and it is mounted to the radiator, how could it give you the precise heat in the room what you need? As far as I know the max temp is 25 Celsius on the TRV, so is it enough to heat up the room to 21-22 Celsius? Thanks for your help.

    My experience.…

    Assuming that your TRVs have free airflow and are not blocked by furniture, curtains, radiator covers or laundry etc. then my experience is that they work as well as can be expected.

    But, of course they measure temperature close to the heat source and it will take time for that heat to reach every corner of the room and to pass the heat to walls, ceiling, floor, furniture. After time the temperature within the room will be close to that of the TRV. Whilst a room is being heated, however, expect some temperature lag until equilibrium is reached.

    As an example, my lounge TRV is set to 20C. The boiler finished a heating cycle 10 minutes ago. The TRV shows a current temperature of 20C and a thermometer across the room shows 19.9C. That's close enough for anybody, I think. The room has been set to 20C for the past five hours.

    Maybe more interesting than the equilibrium state is the actual heating profile. Here is the temperature within the room for the past 24 hours. Heating went off at 22:00 and resumed (slowly) from 07:00.

    Wireless temp sensor is definitely the way to go for more accurate readings but I only have one in a particularly cold room (3 outside walls and above garage) while the rest of the rooms manage OK with just the TRV sensor.

    I would add more WTS but they're pricey considering they lack the switching capability of a smart thermostat. The stands are also ridiculously expensive for a piece of plastic. Wall mount if you can!

    Thanks for the comments. I am confused about the correct part number of the TRVs. Which one is the smart one: V3P-SRT01 or V3P-4SRT01? I do not want to buy the basic ones. Thanks
