Red wire to R on thermostat red on furnace and red on heat pump Same with white except w1 on thermostat. Blue to common on thermostat common of furnace (probably brown but will be marked) and blue to common on heat pump. yellow to Y on thermostat and straight to heat pump. Orange to O on thermostat and straight to heat pump. If wired correctly with no shorts fuse problem should be solved. commonly people leave enough wire exposed inside the t-stat for wires to short together. This will blow the fuse. Hope this helps. I understand the frustration.

I have an 2 zone outdoor unit. 2x 9000 btu Aura indoor units. Both on 16ft lines. When i installed the first indoor unit and ran the setup the system would shut down every few mins and then restart after a while. Error code P6 would flash and the run and timer lights would alternate.
First assumed a defective compressor or so but after hooking up 2nd unit it went away. Seems that hooking Both units up to a 2 zone is required otherwise the compressor sends a fault code P6.
