Is my heat pump OK?....... This morning I noticed some frost on my condenser while in a Heat mode. Is that normal or is my defrost timer going bad. Any idea?

Hello, I have attempted to wire a Honeywell RTH7400D to replace a White-Rogers Heat Pump Thermostat. When I turn the A/C on, I get heat; I have not attempted to turn the heat on and see if I get A/C. I believe I have a heat pump system. The out door unit is a Goodman Model CPLE24-1A and the indoor unit is a Goodman Model HKR-05. Unfortunately, I do not know how the old t-stat was wired in – I tore the tags off thinking I was good! Here is how I wired the t-stat: C – B (blue) W2 – W2 (white) G – G (green) Y2 – jumper into W2 Y – Y (yellow) L - empty O/B – O (orange) Rc – jumper wire into R R – R (red) According to the installation guide on page 18, I have it set to 9 (Function 0170). I set it to this because on the inside of the White-Rogers t-stat, it says “2 stage heat/ 1 cool”. I opened the outside unit and it is wired as such: Y – yellow wire R – red wire O – Orange wire W2 – White wire C – Blue wire I had a green and black wire; both were not used in the outdoor unit. I am not sure it my wires are set up correctly or if I performed the system setup properly following the Honeywell Installation Guide. Any assistance is greatly appreciated and thanks.
