Upgraded from Honeywell to Honeywell thermostat

So the up button didn't want to work unless you really smushed it and wiggled it around. So I bought a new one. I hooked it up about 3 months ago but now the heat doesn't blow any heat, just cold.
Here is the old one.




So I put up the new one wiring it like the manual says for a 1h/1c heatpump.


It worked great all summer for the a/c.
Here is a link to the manual. https://digitalassets.resideo.com/da...3-00181EFS.pdf

Welcome to the forums.

Your wiring is ok.
Most of the default program settings are ok.
You must change the following three for your system.

200 = 2 - heat pump
205 = 7 - Air to air heat pump
218 = 1 - B (O/B in heat)

Thank you for your reply. I was sure I already had that set correctly, but I went and wrote down all my settings to be sure.

Don't know if this helps but the Heat pump is a Rheem.

Your settings look ok.

The O/B supplies power to the reversing valve. The majority of the companies use O for cooling. That means the valve is powered to cool. Rheem and Ruud are two companies that use B for heating. That means the valve is powered to heat. Just the opposite of everyone else.

If I was checking your system.... in heating mode.... I'd go out to the condenser and check from the blue wire to the C wire. You should see 24vAC there. If you do see it there.... it could be a defective reversing valve coil (open) or a problem with the defrost control board inside the condenser.

Do you get heat in emergency mode ?
That would shut down the compressor and use the electric reheats.
