We have the same thermostat, although we only have the one zone, I would assume the second AC would represent zone 2. These do also have two separate programs, 1 and 2
Since these do have two programs, it might be possible to have #1 set to have the furnace come on at lets say 8:00 am with the temp set at 65 degrees. Maybe if program #2 is set to have the Fan come on and the time is the same on both programs the AC fan might be on while the furnace is working. It is not normal for both to be on.
Try setting program #1 to Furn and program #2 to Off and see if that makes a difference.
One thing to watch for if you are going to be moving and the furnace is set to a temp of say 65 degrees and the inside temp is less that that, and you travel with your propane on then the furnace will come on and waste a lot of propane, not to mention battery, if the propane is not on, the Furnace will try to come on, this uses a lot of 12V battery power when you don't want to have the furnace on. Before you move set both programs 1 & 2 to OFF. I learned this from experience.
