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. 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.

Any help would be most appreciated.
Thanks in advanced!
