Air Conditioner/ Heat pump question

[2 Yoopers]

I purchased a used 2015 Montana 3711 FL with the Leagacy package. It has one thermostat located by the stairs to the living room, that has a button for zone 1 and zone 2 adjustments. When I flip through the options there is nothing in either zone for heat pump. Yet when I turn the furnace on, the rear 15000 btu air conditioner comes on with it. Not sure if that is normal or not?

AFAIK the 2015's never had a heat pump option, The AC fan running with the furnace is a well known "feature". It occurs if the fan speed is set to anything but "Auto" when running the furnace.
