, posted Mon 15 Aug 20:43  
I am trying to update my old Janitrol HPT18-60 to a programmable Honeywell T8112. It was wired Y-yellow, G-green, R-red, O-orange, W2-white, E-black, C-blue and there was a tan wire folded behind the wall not used. The new thermostat has a W,Y, G, C, and an R & Rc jumpered together. I assume that W-white, Y-yellow, G-green, C-blue, R-red but Rc? and what about the other wires? Please help. Thanks in advance. By the way, I tried the honeywell website with no luck.
