We just had our local Carrier salesman out and he was telling us about the 1600 and the universal controller. Does anybody have any experience or anything good/bad to say about it? It sounds pretty good to put in smaller commercial buildings so that we don't have to rely on JCI. Which would make me happy. Is it hard to program? I have a job in mind that I would like to use it for, could I go in blind and wing it? The salesman of course said that it was no problem but that is what he gets paid to say.
