Sounds like it could be a wiring problem or faulty stat. Time to get out the multimeter and wiring diagrams.

Honeywell wiring plans are available on the web. Not only do they work, but following them will give you a working system and will also give you a fighting chance of understanding what is going on if you are called bck in three years time.
