How to isolate Danfoss RAS C2

[thehound]

Hi, I need to isolate and replace a radiator.
How do I isolate after removing the danfoss TRV?
(I’m assuming I can’t just turn the TRV to off but need to remove it and do something to the valve underneath)
I have isolated the tail valve at the other end of the the radiator.

Thanks very much for any help.

Yes, just do that if you are only replacing the radiator.

Yes, you can, but I’d make sure it’s not passing, or gone off fully, so once done (turned to off), open the bleed vent and make sure the water stops flowing (Approximately 10 seconds).

If you remove the TRV as you call it, the sensor and leave that disconnected then you are about to get very wet , you need to leave the sensor in position and set to closed
