air and heat problems
« on: July 31, 2017, 11:02:24 PM »
We just purchased a used 2015 Winnebago tt 27rbds and when we turned on the heat it came out of the floor vents (warm air) the air also came out the ceiling vents (cool air).  I don't think this is normal as we have had many campers over the years and they only came out (heat at the floor) and/or air at the ceiling ' Ant suggestions on a fix?

Yup, that is what happens with our Dometic wall thermostat if I leave the fan setting on Lo or Hi and select furnace.  Set your fan to Aux and that won't happen.  On ours you select the fan mode then press the + button until "Aux" appears in the window, then select furnace.
