heat pump help

I changed out a Rheem heat pump with a Goodman GSH wired up everything but the new unit seems as though it is reversing the low side line is heating up and the high side is cooling.
I followed the old wiring when hooking up the thermostat.
Tstat - condenser
Blue - common
Orange - orange
White - white
Yellow - yellow
Red- red
The only thing not sure of was the original wiring on the a Rheem white from the tstat went to D on the board if there any suggestions please help.

The reversing valve on a Rheem / Ruud is the reverse of almost every other brand. You must reconfigure your thermostat O/B terminal to now be O, or move the wire from B to O on the thermostat.

If you post the stat make and model number we can offer further assistance.

B energizes the reversing valve in heat mode and O energizes the reversing valve in cool mode.
