Hi there, It's probably my video you've found: https://youtu.be/MpfQLsWLiic It's based on a mod not by myself but others on the .com forum, many people have done it in the past and on this forum so if you search you'll find many people that have done it. Worked great and haven't seen any negative issues raised by anyone so far on it. Hope it does the trick, getting to the original thermostat has been done (several people) but I've never managed it myself, access was just too difficult as tried several times from top and bottom and couldn't get to the bolts to sufficiently undo.
