This all looks correct There should be a function 2 set to 0 also (You heat pump reverses in COOL mode)

Expert:  airheatman replied 10 months ago.

I will stand by if you want to try everything.Did you turn off power to air handler before you started? If not and system does not work, look for a small auto type fuse in air handler which may have blown if any wires touched and sparked.

Thanks. Going to fire it up...
Expert:  airheatman replied 10 months ago.

Let me know if everything works.If not we will go from here. Keep in mind we will have a 5 minute delay between heat and cool before thermostat allows unit to come back on.
