Noma Thermostat vs Old Thermostat
 
I have a Noma Programmable Thermostat with places for 4 wires to be connected. The Problem? I have "5" wires coming from the furnace that were all connected to the old thermostat. I was told I could wrap the #4 wire and not use, but that resulted in no-heat. http://www.diychatroom.com/images/icons/icon9.gif So obviously this wire needs to be connected, but I don't know to where or with what. I have a picture of the old set-up showing the wires labeled etc.
G-Green
RC-Red
W-White
Y-Orange
4-Black

Any help would be most appreciated.
Thanks in advanced!

DIYW,

This is considered to be a subject for the HVAC Forum not the Electrical Forum. You will catch the eye of relevant experts over there. The answer to your problem may be found in #CARRIERMAN's excellent post:
