Newbie trying to install an XL824 on a Goodman Heat Pump system. Just purchased house and old owner took the old thermostat. Have 8 wires on wall, not sure if all are used. The model number shown on the unit is ARUF042-00A-1A. I believe its a single-stage unit.

I attempted to wire it following a post I saw on this site:

Aux1

Aux2
RC - Jumped to RH
RH - Red
B/C - Blue
O - White
Y1 - Yellow
Y2
G - Green
BK
W1
W2
W3
ODT

RS1
RS1

The unit turned on and appeared to work - I turned heat on and set the temp to rise 2 degrees. Heat came on raised properly - the thermostat then showed Standby once temp was reached, but the unit kept heating and didn't turn off for several more degrees. Showed Standby, but would not shut down. I had to shut down system by pulling the thermostat after about 30 min and several degree rise above setting.

Then tried the 1 Stage Heat Pump with Non-Variable Fan from the manual:

RH - Red
B/C - Blue
O - Orange
Y1 - Yellow

When I turned on A/C, the heat came on - unit showed Cooling, but was pumping out heat.

Any help would be greatly appreciated.

Need a picture of the wiring at the air handler and outdoor unit.

PS. That model number is only for the air handler. It would be nice to have a model number of the outdoor unit too.

Cheers!

Did you tell it to energize O in cooling mode.
