My 3 year old CM-15A died (won't store timers properly in interface) although it will work OK if I control the the timers from the PC. When I store them to the interface, they get all messed up and lights come on during the day, etc. I ordered a new CM-15 and that fixed the timer problem but it did the same thing as yours (would not tranceive RF commands). I tried setting it for auto and also manually selecting the 2 house codes I use (A&B) but it still would not respond to RF remotes. The next day, I gave it one last try before returning it and it started working (by setting it back to auto). These things are very finicky but nothing else will so what it does for $50. -Joe
