We recently purchased a used 2011 Wildcat 28RKS. Everything works beautifully except when I set the thermostat to heat, the furnace comes on and heats great but at the same time the roof top air comes on!I talked to the previous owner (friend of ours) and they hadn't run into the issue.
It's a single zone Dometic LCD thermostat .
Any suggestions?
Going camping for Easter weekend and its still chilly so we will need some heat.
Here is an excerpt from this other forum. It has to do with the settings on your digital thermostat not being set to auto

Use the On/Off Mode button to select FAN. Then use the +/- button to select either Hi, Lo or Auto. When using the AC and the fan is in the Hi or Lo setting it will run continuously while the compressor will cycle on and off. In the Auto mode the fan will cycle on and off as well.
If the fan is set on Hi or Lo while using the furnace, the AC fan will run continuously, so be sure to set the fan on Auto when using the furnace. You can, however, leave the AC fan running while using the furnace to help with condensation problems.
Use the On/Off Mode button to select COOL. Use the +/- button to select the thermostat temperature setting. (same procedures for the furnace)
When using the AC in the Auto mode the fan will run on high when the room temperature is 5º or higher than the thermostat setting. When the room temperature drops to within 4º or less than the thermostat setting, the fan will stop for a few seconds the start again in the Lo mode.
Hope this helps.

You need to change the fan mode. If ya got the Tstat manual look on page 8 & 9. Like stated in post above 'be sure to set the fan on Auto when using the furnace'
We had this same problem with our new Salem. Took it in, and the tech found a wiring problem down at the furnace (which is under the dinette seat). Apparently it was a relatively simple job to fix once the problem had been isolated.

Thx WMTire and Wiscampsin.You are correct. It's a thermostat setting. I reset the fan on the thermostat to "auto" and the problem went away. It's an option depending on how you program it. GMT, you're right in saying te circulation is. Good....just don't want it running all the time.....noisy.Thx to all
Cheers
