I can set the on and off time for the timer to use standby mode through the Services page. Is there a way to change these programmatically? I can’t use a default setup, the on and off times may need to change.

Hi,  
The current AAF API does not support to create an app with power management ability. You can only set up standby mode through Services tab on ACEManager. I would suggest to use “Use Standby Mode” = “IO + Timed” and control I/O pin properly.  
Thanks,

Thanks for the reply.  
We can’t use the I/O pin, we currently use it as an output, to drive a relay.
