I have a, seemingly, faulty Wiser radiator TRV whereby the two outer lights flash and the centre light is on. This should indicate that it's ready to attach to the radiator but even after doing that and turning to either + or - it still remains the same. I've been in touch with Drayton and they said it does appear to be faulty and to return to where I purchased it. I therefore got in touch with Amazon and they said keep it and they'll refund it!
So, now I have a free TRV I'm just wondering if there's anything else I can try or whether I can take it apart (I've removed two screws from the underside but they don't appear to do anything?!
Any ideas or help would be greatly appreciated.
