Aircon and heater thermostat wiring

[ianrjam]

When decorating, we took the thermostats for the Suburban heater and Armstrong aircon off the wall of our 78 Tradewind. The wiring colours were carefully noted on a diagram of the two stats. The paper was carefully kept with the stats. But, when we came to put it all back, guess what? The little piece of paper had gone to where little pieces of paper go. I think there are six wires - two thicker (blue) three with fork connectors crimped on and one snipped (brown) which seems to be the same one that hangs around in the aircon unit - also snipped. Here in London England, we can't drop by our local Airstream dealer. Can anyone help?

The safest way to proceed is to take an access cover off the furnace and see which wires are connected there. Same for the air conditioner.

But see if this site, which lists color codes for home HVACs helps any.

The thermostats for my 75 are in different area of the trailer. I did some work on my heater and I remenber that the wires to it were both blue. Yours may be different. Be safe and do what Tom said.
