Daikin BRC2C51 A/C not working? Try this!

A fairly quick fix to the Daikin BRC2C51 A/C that wouldn't respond, Hottest day of the year here in UK, hotel room wasn't much cooler, is now! Only attempt if your confident and skilled with electrical appliances and please please please use common sense, no wet fingers or touching anything other than the buttons! Its most likely 24V but just be careful is all I'm saying yo!
