Ok that all sounds good. Do you know how to get to the installer setup menu so we can match thermostat to your system?

Expert:  airheatman replied 2 months ago.

Lets make sure functions are set as follows:

0170 - 7

0180- 1

0190- 0

0240- 9

0270- 9

Any other functions are at your discretion.

If any functions listed do not show available, this means thermostat has setup based on a previous selection.

I dont have a heat pump it is an gas furnace
Expert:  airheatman replied 2 months ago.

If you do not have a heat pump you should not have a wire to O/B .That is a reversing valve terminal for a heat pump. What is model on outdoor unit?

OK you are right about not being a heat pump. Look and see if that orange is connected to anything at furnace or outdoor unit

Expert:  airheatman replied 2 months ago.

You will want to change the wiring as follows:

Move the white from AUX over to W which is same terminal as O/B

Leave the orange disconnected

Then you will need to go to the setup menu and set as follows:

0170 - 1

0180- 0

0240- 5

0270- 5

Any other functions are at your discretion.

If any functions listed do not show available, this means thermostat has setup based on a previous selection.
