Can't make AHP turn on the modules

[mgreen414]

  I've had my system for about 2 years with very little problem. It's a system with about 40 different modules which uses a bridge. All of a sudden the timers no longer work. I have changed the batteries in the transmitter. If I turn on the lights manually, the AHP will turn them off as scheduled. Can anyone give me suggestions?

Thanks, Mike Green
