You also say there is no room stat. Add one ASAP (and a zone valve if it
has
none) and make sure other rooms have TRVs too. You are wasting gas like it
grows on trees.

Slightly puzzled - I thought the OP said that all radiators had TRVs.
If so, why do you need a room thermostat?
In fact, which room do you put it in?

If I understand correctly, a room thermostat turn the CH off once a specific
room has reached a certain temperature.
At this point any other room which is below optimum temperature cannot heat
up.

This leads me to deduce that the room thermostat should be in the room to
heat up last and cool down first, so that all the other rooms are able to
come up to temperature and then shut down the radiators via TRVs to keep at
optimum temperature.

If this is correct then the remote wiring required to install a thermostat
just to regulate one room seems pointless - just give this room a TRV as
well.

Or am I missing something?
