I am trying to replace an old thermostat (White-Rodgers) with the aforementioned model and connection letters on the White Rodgers model are as follows C=black wire L = Not used W2 = white and brown wires E = blue wire R = red wire G = purple wire O = orange wire Y = yellow wire ... please inform me about which wires go to the terminals on the RTH6350. We checked page 25 of the included instruction manual and some of the letter codes indicated therein do not coincide. Thank you.
