3650bh rear fan constant with furnace on

[mpiac]

I've tried finding some literature on this but have been unsuccessful so far. In my 2015 3650bh, when I turn the heat on, the rear fan on the AC unit runs continuously blowing out ambient air which counteracts the heat coming out of the floor ducting. Is this normal? As a result, the middle and forward part of the rig or comfortable, but my kids are freezing in the BH portion. Thanks for the help.

On the thermostat that runs the furnace, change the fan setting to AUTO. If set on HIGH or LOW, the A/C blower runs any time the thermostat calls for heating or cooling.

Ok, another dumb question. How do I get it to turn to auto? It's a Dometic thermostat. I'm new so I haven't figured out how to post a picture, but it only has the On/Off-mode button and a + and - button. When I cycle it through fan, it shows Hi. How do I change that to auto? I've tried a number of button combinations and haven't found the correct one.
Thanks.

Cycle it to FAN mode and press the + or - button to cycle thru the settings.
