I just checked around the area that is using House Code A and I do have a TM751 Transceiver plugged in. I have removed it and will test once again. Also, I was testing the TM751 as I could not get it to turn on and off remotely with either Home Auto Pro or the Universal Remote. I am left with the notion that this Transceiver might be receiving RF but the internal module is not functioning. The On/Off button still functions. I will return with test information in a bit.

I just tested and both Home Auto Pro and the Universal Remote are functioning properly now. With HAP, I see just the normal commands in the Activity Log. With the Universal, I see one RF Receive and then two sets of the "on" command sequence. Before I was seeing two RF Receive and then three sets of the "on" command sequence.
Observation: I added the TM751 some time ago as I thought that I was not receiving some of my RF signals when away from the CM15. At this point however, I will need to retest all of that. Also, I will check tonight's Auto Schedule from HAP and see if all lights come on. Hopefully this is the solution and I can go on to my next problem. I will report back my evening findings.
