Ruud heat pump to straight cool with heat strips I have a Ruud heat pump going to what was a straight cool with electric heat strips in a mobile home which has no wiring diagram and has 5 connection?

I'm afraid your question is not very clear. Your heat pump is basically an air conditioning unit with back up heat strips. If your thermostat is wired correctly and I'm certain it was from the factory, then the AC and heat strips will never come on at the same time. Is it not going into cooling mode? Ruud has wiring diagrams for most all their equipment on the internet. With a little research, you should be able to find yours. The Model # of your heat pump is the key to that.
