Heat Pumps - Do I have them?

[Old Scout]

My compliments to Rdownward for his persistence in tracking down the wiring and the associated dip-switch settings. Normally, the problem with the furnance is the need to set the thermostat on zone 1--this is how the dip-switches were set at the factory. Apparently, someone tried to change the dips so the furnance was "slaved" to zone 2. Not sure I would have thought about changing the wiring so the dip switches were compatibility. Well done!!!!!

Just because the coach built in front of yours has heat pumps doesn't mean that yours does.

Agreed, the boards need changing to use the different thermostat. There is a place that repairs the old 4 button ones though. I thought I had the info saved someplace but I can't seem to find it now.

Four button DUO THERM System

Five button DUO THERM System

If you change systems you will need new controls for both AC's for 5 button to work.
The PDF's will help when the dip switch's have to be set to indicate the furnace on screen and get it to operate.

Thanks for providing the Troubleshooting PDFs Wayne. That is GREAT information to have for those of us who have the ability to do the testing, etc. Much appreciated.
