If you have the book you have the info. Look in the index for electrical symbols,ladder diagrams,etc. If you lose your internet connection you can still find the info in your book. ;)

GOOGLE "heat pump wiring diagram" (http://www.google.com/search?sourceid=navclient&aq=t&ie=UTF-8&rls=GGLD,GGLD:2003-40,GGLD:en&q=heat+pump+wiring+diagram) :D

Learning tech, Here are a couple of pictures of wiring diagrams from a 1992 York E1FB heat pump. The 1st picture shows the airhandler with electric backup heat. The 2nd picture is the outdoor unit schematic - it shows the thermostat, outdoor components, and relays at the airhandler. They might be a little hard to read, but I hope it helps.

What book are you in?

A ladder diagram gives you more than just wire connections. Usually, it works like a ladder when it comes to sequence of operation also. You start at the bottom, and must successfully negotiate a rung before you climb another one. In the diagrams previously posted, the 1st is a ladder diagram, the 2nd is a schematic.

Using his ladder diagram, you can see that the thermostat is the starting point for a call for cooling. You step up one rung at a time. (No this was not a very good example).

I asked the Ruud factory trainer if there was a shortage of paper in Arkansas.

He looked at me a little funny until I showed him the "playing card sized" diagram.

If you never complain, they'll just keep doing it.
