-----------------------------------------
"For the Compose switch, when you receive it, program it to X-10 Compatibility mode.(It explains how in the manual) Also, program it to CI mode if you want to have two-way status.(it's configurable) To operate the different levels you can just send preset dims to change the levels. Martin was right. If you send 10 or 20% it will go to low, around 50% will go to medium and around 90% to 100% will be high. You can program the led intensity. The switch can even identify excessive noise on a given circuit. Quite a few options on one switch. Let me know if you have any questions when you get it."
----------------------------------------
I haven't been able to find technical information about performing the above configuration for the CCWHISPLC. To the extent that the Preset Dim command is required to operate or receive status info from this module, you will not find ActiveHome Pro very useful. AFAIK, the only way for the CM15A to send a Preset Dim command is with the AHP Software Development Kit (SDK). Note: the Preset Dim command should not be confused with the AHP Extended Preset command
