Tuicemen and Dan Lawrence,
Did some testing, Green is the color of the switch both ON & DIM settings if done while AHP is connected to the CM15A. The switch will be Green when turned on or dimmed locally at the PC or from any other remote. If however you have the CM15A disconnected from the PC any module on the "Monitored House Code" will be Green or Blue for any operations done to those modules while the CM15A was disconnected. The Blue are modules that are on but dimmed < 100%, the Green are the ones just turned on. Try it yourself, disconnect the CM15A from the PC, use a remote and turn one lamp ON and another lamp ON then DIM to around 50%. Must be modules on monitored house code. Then reconnect the CM15A to the PC start AHP, the lamp that was on will be Green and the dimmed lamp will be Blue!
I think this is some way of letting you know the status of the modules after connecting to the CM15A.
Regards,
