Question About Honeywell Thermostat RTH111/RTH221
Installation...

I have a RTH111 and it is vhorizonal configeration, not vertical as shown in your examples. I do not understand this. On page 6 of my installation manual it states that it will not work if wire R, RC, RH, etc \. If my previous thermostat has this RC wire do I electric tape it of and not connect it or?
