How to change installer functions on Honeywell Prestige HD?
I have just installed a Honeywell Prestige HD, and all is fine except that I need to change the setting on installer function 190, "Reversing valve". Should take me 1 minute, right? 2 hours later, I am posting here in desperation. How do I change this setting? In the installer menu there are lots of settings, but no numbers, and no setting called "Reversing valve". Supposedly you can update settings via USB - is that the only way to change this setting? I tried it, but there is nothing in the install guide about how to do it, and all the things I tried failed. All help greatly appreciated.

Thanks for taking the time to reply - I appreciate it! I know I need to set it to O. Currently it is set to B. My question is not what to set it to, my question is how do I set it to O? What do I have do in order to change the value of #190 from B to O? What do I press on the keypad to do this?

Found it! I had to change the system type from "Conventional" to "Heat pump" - then the setting appeared! And now AC seems to work.
I now need to verify if heating works, and I am a bit confused. My old thermostat had an O wire and a W2 wire. None of the wiring examples in the install guide match that - none of them indicate use of the W2 wire. Should it be connected to AUX?
I have a Carrier FC4CNF060.

THANK YOU SIR FOR YOUR HELP! Really appreciate it. Turns out I have a 2H/1C Heat Pump, and it was wired correctly. Now that I changed the system mode from Conventional to Heat Pump, everything appears to be working perfectly. THANK YOU!
