I've had a similar problem a few times but only with one code being sent. It always turned out to be something squeezing, pushing, or in some way hitting one of my remote buttons. Two different house codes, however, means this is not that simple.
It could be the AHP interface. Unplug it from the wall and remove its batteries to reset it. Plug it back in. Do not re-download your program yet. If the problems stops, the hardware is good. Now re-download your program. If the problem begins again, it's likely some loop in your program.
If the problem is not your program, it could be a bad remote--locate them all and remove all the batteries one unit at a time.
If the problem still persists, it could be the V572. Unplug it and turn on the AHP receiver. If the problem stops, the V572 could be the cause.
If the problem is still continuing, there are -- fortunately -- lots others on this site with more ideas I'm sure.
