TRV tear down . . .

hugbilly

iFixit has published a tado° TRV tear down guide, it’s very easy to undertake and by chance I have a unit which has developed a fault; the motor seems to be partially jammed so I’m keen to try and free it. However, although the guide states the circuit board is held in with two cross head screws these are in fact very small Torx fastenings. I wondered whether, if anyone else has dismantled a TRV, they might know what size of Torx driver is required?

Yes, I'm sure they might! (sorry couldn't resist!)
