This is the current wiring.

HP (brhs0241bd) (1ph) AirHandler/ Tstat Hunter 44132
Furnace (attic)
Wire in wire-out connections
R (24v Red)------------------------- R -------------red 24-------------------------------R
C (Black spliced to Blue)--------- C--------------Blue---------------------------------C
Y (compressor-yellow)----------- Y--------------Yellow------------------------------Y
O (orange-reversing valve)------ O--------------Orange-----------------------------O
W (brown spliced to tan)--------- W1------------spliced to white (what are these)
W1/66 (white)----------------------- W2-------------spliced to black (what are these)
G--------------Green------(blower/fan-AH)----G

These are my options on thermostat

Just confused as to where the for the W1 and W2 connects to on the thermostat.
Also as I looked at the manual for the Heat Pump and installation instructions it says that the W(brown wire) that is splice to the tan wire should be going to the W2 on the Air Handler. As you can see the set up that is there now has the brown/tan going o the W1, was not sure if I should correct this as this is how the unit was installed 4 years ago.

I've looked at other thermostats for there wiring instructions and the diagrams show only w1/66 going between the HP and AH, not HP to AH to Tstat.

Fyi. Heater works, ac does not blow cold air. I do believe it needs to be recharged. But since I the old thermostat was replaced I wanted to make sure all wiring was OK before a tech came out. It was wired for conventional and the selector switch on the back of the thermostat was originally set to conventional and gas furnace. Since then I had changed it to heat pump since that is what it says on the label on the condenser/HP unit outside. There are also different terminals to connect the wires to if you have a heat pump, this is where my confusion is.

Thanks in advance.

I apologize I messed up the layout, I forgot that the HTML script would not recognize my indents. So from left to right on the wiring colors far left is HP then AirHan then to Thermostat. And just ignore the part that says wiring options for thermostat. The model numbers of products were provided to use if anyone needs reference thanks.
