Trailer is a new 2920BH with Atwood furnace, Dometic AC unit, Dometic digital thermostat.

A few weeks ago I tried out the furnace for the first time without AC power and I only recall it running the floor blower vents.

Today I tried the same plugged into AC power, and the roof unit fan is also running. Floor vents are blowing warm air.

Is that right? I suppose the roof fan is just helping circulate the heat. But since it's kinda loud, is there an easy way to run the furnace without the roof unit fan?

TIA
