Hook the orange wire to the O terminal and nothing to the B terminal.
The difference between the 2 is when they are energized. The O is
energized in cool which is the most units are wire (including yours)
and the B is energized in heat which is the way Rheem, Ruud, and
Weather King units are wired. Make sure you kill the power to the
indoor unit because if you touch the wrong 2 wires together by
accident you'll pop the low voltage fuse. As far as programming, just
read the manual not to hard on White Rodgers T-stats. Good Luck!!!

You don't even know me. For such an idiot my answer is correct.
Don't most heatpumps have strips as auxillary? Unless it's a dual
fuel or water furnace that's the way they all work except for maybe
ground source. Did you read that last statement before you posted
it. It makes no sense and I'm the idiot.

I made no assumptions, only statements.

$7,000 for 2 systems is really cheap unless you provided the equipment. If
the installer provided the equipment and t-stats, the stats are still under
warranty. Call the installer back to make it good under warranty, unless he
is out of business because he didn't charge enough.

What did the directions to the thermostat say?? What do the books for the
air handler and heat pump say?? You need to know if the RV is energize in
heat or energize in cool. I know what it is, and will leave you to your
homework to figure it out.
