Red Wire - to R & Rc
Green Wire - to G
Yellow Wire - to Y
White Wire - to Aux (with a Jumper to E if they are separate terminals)
Orange wire - to O/B
Copper wire - Tape off
You must also configure to match your system.
170 = 7
190 = 0
240 = 3

It should take 5 minutes.
The old stat required the jumper to energize the outdoor unit on demand for heat as well as cooling. The new stat does this without a jumper when it is configured for heat pump operation. (option 170)

Interesting.
Not sure if heat is working fine. When I put my hand over the air coming out it feels a lil bit warm but not hot hot.
When you say option170 I assume for my new thermostat that is the equivalent of Function 1 and I choose heatpump with aux? which is 5?
Thank you for all the help

Yes, Set function 1 to 5.
2 = 0
Does the outdoor unit run with a heating demand?
Does the outdoor unit discharge cold air from the top when it is calling for heat?
2 = 0
