In the heat pump unit there are 2 leds. Led 1 is on and led 2 is off. The diagnostic chart says press set. What does that mean. There is no reset button.

Some Rheem's have a reset button on the outside of the unit down low. What's the model number?

Found out how to reset the panel. There are 2 test poles which you need to short out. After I did that the unit reset and seems to be working fine.
