I don't see this error code in the manual. I do see nP as an error code for Window Switch lockout. I just had this happen to me and they had me reset the control board.

Remove case, flick master switch to OFF for 10 seconds. Press Heat/Cool same time turn switch back on HOLD until off light comes on.

You should be fixed. Just had to do this for my unit. I was playing around with the settings and turned on the window switch option by accident.

4 wire what? Was the unit working before this? Sounds like some wires crossed

the unit works by chilling air and the byproduct is heat in the compressor, this is used for heating in the winter and then reversed in summer to blow cold air. It has to blow cold and warm up before it can blow heat.

I've replaced many Amanda control boards. They have micro relays attached to the board. These relays are about a half inch by 1 inch in size, and control line voltage to the compressor and blower motor, and give up quite often. Its probably the board if its a digital controlled board. If it has manual, turn to select, type knob, it will be in that fan section knob. Hope this helps!
