Anybody done it? I have a customer (McDonalds) who refuses to give up on his Beacon 1. The problem now is the board (I think). It won't modulate the EEV anymore. It's either open to 255 steps or closed. I've tried to convince the bullheaded operator to do what Archie at Heatcraft says to do, which is to rip it out, put in a LLSV, TXV and stat but to no avail. He really and I mean REEEEALLY loves his "Smart Controller". I'm stuck. The wholesaler no longer carries Beacon 1 boards or EEVs. Is it beyond stupid to even try to convert this to a Beacon 2? Help!!!
