Replacing a TRV head

[LionelL]

Hi all,
Hopefully someone can help me.
I need to replace a ACL Drayton Invensys RT212 radiator TRV head (the valve part is fine).
Instead of a straight swap, I'd like to take this opportunity to install a valve with a remote sensor - the current TRV is right next to a ventilation hole so doesn't work too well.
Are any of the other ACL TRV heads compatible with the valve-part of the RT212?? The TRV3 or TRV4 maybe???
Thanks for any advice
LL

would have thought the TR 4 remote sensor would fit
However take RT212 head down plumbers merchants and check thread the same on backing nut,you may find other makes fit also,like myson

The RT212 and the TRV4 use exactly the same body, so all you need to get is a remote sensor. There are two types available:

ETF2: 2 metre remote setting kit Part no: 07 55 002
ETF6: 6 metre remote setting kit Part no: 07 55 006
