My apologies. The results I posted were the observed results but I forgot I had another EZX10RF in range of the credit card remote. The X10 messages being traced by my ISY were coming from the other EZX10RF, not the one that had the house/unit code unchecked. When I unplugged the other EZX10RF the X10 messages stopped.
