Hiya folks... I have looked all through these threads to find an answer and can't find it so, I'm going to see if someone can help me. I'm in a 1998 Jayco Designer 5th wheel. My A/C is a Coleman 7000 Series and my furnace is a Excalibur 8900 III. I replaced the old non-working thermo with a honeywell RTHL111 series.
The problem is I have no yellow wire or brown wire. The wire colors in the AC unit are thick (red, green, blue and white) wires.
I also have an auto vent fan which uses a thin white and red wire (going to a seperate thermostat) the 2nd thermostat wires have two more spawned wires which were taped up behind the wall.
The way I have it hooked up now is in the picture. The air conditioner does work with the way the wires are going into the thermostat. I just dont know how to make the furnace work
I just noticed that the wires coming out of the AC are as follows:
Y = blue wire
b = red wire
gl (low fan) = white wire
gh (hi fan) = green wire
but still when I hook them up based on the way they are hooked up in the AC, neither the ac or furnace works.. soooo.. any suggestions on how to hook it up to the honeywell?
