Is anyone else a bit unsure of the interior zones within the house? Some of the rooms aren’t exactly graphically blocked out. In the manual, it shows the interior of the barn which is made up of 4 interior zones, but what about the “living room?” Is that just ONE zone? There is no clear board graphics that would suggest any type of division; or should we just assume that each board section is a 3 x 3 set of zones?
