I think I have a similar problem. I've had a CM-15A Active Home interface for a couple of years, and it generally works OK. And I’ve never had problems downloading my timers and macros. However, I just made some minor changes to my timer programming, but when I went to download the changes to the interface using “Download Timers and Macros” I got a message that says “there’s not enough space in the interface to download your timers and Macros”. But at the bottom of that box it shows my Current Memory Usage as:
Macro Memory 0.00%
Timer Memory 0.00%
Dawn / Dusk Memory 0.00%
Need to Free 0.00%
What can possibly be wrong?
In an effort to troubleshoot, I cleared the interface memory using the A/H software, thinking perhaps somehow it was locked up. That had no effect.
I unplugged the interface from the wall outlet and replaced the batteries – still no effect when I tried to download.
I unplugged the interface, removed the batteries and let it sit for half an hour, thinking maybe a prolonged power outage would reset it. Still no luck.
Ideas?? Right now I have a dead system with no automatic control, although with it reconnected to the power outlet, I can issue commands manually through the Active Home program.
P.S. When I go to “Hardware Configuration” in the “Tools” menu, it shows Memory Configuration as
Macro Usage 4.94%
Timed Events 23.60%
Dawn/Dusk 6.79%
Available 64.67%
which I think is about right. Need ideas!
