I just bought an Aprilaire 700 from Amazon and awaiting its arrival but decided to get ahead and see how to wire this thing. Upon looking at the schematics of my Waterfurnace 5, its not as black and white as a fossil fueled furnace. Anybody know how to wire this thing up the way Aprilaire wants me too? I see the R and C connections for power but the other 3 connections to either the stat or furnace has got me scratching my head. I have the communicating t-stat too. I really want to avoid the fees to get my dealer to come out if I can. I'm an electrician by trade but not too educated on controls. I have included the schematics from my Waterfurnace 5 and the Aprilaire 700. Thanks in advance.
