There is no way you can wire a heapump with less the 5 wires.

You mean you only have 2 wires at the outdoor unit? Or 2 wires at your t-stat? If you have 5 at the stat and 2 outside you can get it to work. With just a little wire changing.

Yes sir,like you said I have 5 wire's at the t-stat,but only 2wire's run's outside to the heat pump, I hooked the white wire to the (c) and the red wire to the (y) and the unit did come on but it was running on the heat side. I am using for cooling only, so could you tell me how to wire it so the cooling part will work. The unit has a c,y,r,e,w1,o,w2,w3, were do I need to jump it at? Thank you so much for your help!

If this does not work you may need to bypass the defrost control board.

The unit has C,Y,R,E,W1,O,W2,W3 on the t-stat control borad! So your saying to connect the white wire to the C and the red wire to the Y and put a jumper to the O on the control board! Will that reverse the cycle from heating to cooling?
