Thanks for giving me the opportunity to help! Move the "O" wire (light red) to O/B on new stat. Tape the C wire and don't use.
Just wanted to check, Sometimes customers appear to be online, but aren't
Try moving the light red "O" wire to O/B on the new stat. You shouldn't need the C wire
Thats what I have the light red wire (actually orange) is on the O/B terminal and C is not hooked up. Is white wire suppose to be on the Aux terminal?
it seems like I have it wired right . the unit was working fine prior to changing t-stat. I was just upgrading to a better programable t-stat.
Is it not working correctly now?
No , doesn't seem to be cooling
You may need to change the function of the O/B terminal. Some units energize the reversing valve for cooling. This is done in the setup menu
how do I do that? I pretty sure this heat pump use a reversing valve
I'm having trouble finding the installer or setup instructions online, but you should have received this with your thermostat.
I found the setup mode and made the changes. it takes 5 minutes to reset conpressor. Hopefully that will do it
If not, view this video I found on changing a heat pump thermostat. Very good. Click here
