Okay....... don't ask how, but after conducting the successful test of the timer function on one device (lamp module) and the CM15 on the same power bar. I created a new file with the same timers as before on 6 modules. Everything is working according to the timer programs with the exception of one module. It does not turn on; however I manually turn it on and it goes off as programed.
This particular switch (leviton 6381) is the most important one for me as it controls the pr och lights.
I have tried a few thing including placing the CM15 at the panel, i have placed it also on an outlet on the same circuit, still does not go on; however it does go off according to the timer.
By the way, the timer sequence for this device is 'ON +10 at dusk' and 'OFF at dawn'. I have two other devices programed to come on at dusk and they turn on fine.
Any further suggestions?
