I have an Armstrong thermostat model 35614B001, with the terminals being: O,G,Y,W,R,E-with a brown? Wire attached,C-with a blue wire attached,X1- with no wire attached.

I am putting in a Hunter model 44155C with terminals being G,RC,RH,Y/O,W/B,Y1.
What wires go to what terminals on my new thermostat? Please help!!

((Bill_Swan disagrees: waste of time))

Sorry Bill that you feel it is a waste of time. Follow the wires back to the unit as see where they go. Then that will tell you how to hook up your thermostat. Also follow the directions that came with your thermostat unless you think that is a waste of time also.
