I have a new CM15A that replaces an older CP-290. I have several lights in our den that I control with the HR12A Remote Control and the TM751 Wireless Transceiver. When the CM15A is plugged into the wall outlet, it seems to interfer with the dimming operation of the HR12A.
Two of the lights are newer soft start modules (WS4777 and WS467) and the third is an older LM465 module. I can turn all of the lights on and off from the HR12A without difficulty, but I am having trouble dimming the WS4777 and the LM465 when the CM15A is plugged into the wall outlet. When the CM15A is unplugged I can dim these modules without difficulty.
Any suggestions would be greatly appreciated.

The problem is actually the TM751. Unplug it, not the CM15A.
Both the CM15A and the TM751A act as tranceivers to tranceive the RF commands of the HR12 to the powerline where the wall switches can pick up the signal. The TM751A is "impolite" meaning it will transceive the HR12A signal even if the CM15A picked up the signal first and begins tranceiving the long DIM command. With two tranceivers putting the HR12A command on the powerline at the same time, the signals clobber each other.

Problem solved. Thanks Dave. :)

If you need a transceiver, the RR501 is "polite" meaning it does not step on other transmissions, it waits until the line is clear. I use 2 RR501's to receive signals from two SS13A "Stick-a-Switch" units. X10 sells it "bundled" but go to http://www.automatedoutlet.com/, they sell it by itself.
