Heat pump always turns on with fan!
Remove the jumper to G, turn dip switch 8 on, and enjoy.

The jumper between W1/Y1 and G on your board is what is causing the fan problem here.  So, I would remove the jumper to the G wire (from W1/Y1) from the zone board with the indoor unit OFF at the service switch, flip dip switch 8 on the zone board to ON to make it so that the zone board calls for fan when a heat call comes in, turn the service switch on the indoor unit back ON, and enjoy your newfound comfort!
