TRV Isolation

[Doug99]

Hi All
I'm looking to temporarily remove a radiator to decorate the room.
The rad has a standard valve on the left and a TRV on the right.
I aim to remove the rad and leave the isolating valves on the pipework.
The left hand valve will close fully, but the TRV has 3, 2,1,* settings.
If I set the TRV to *, will it full isolate the supply?
I assume if the room temp drops significantly, the valve will open. So how do I fully close the TRV?
Cheers
Doug

Remove the TRV head and replace it with a decorators cap. https://www.screwfix.com/p/drayton-radiator-valve-cap-white-5-pack/5649r

As a backup you can also fit a blanking nut with a rubber seal after you remove the radiator.

Does the TRV not go further round past the * setting? Modern ones have a full off position.
