Just purchased a new system from Volt. included 150 watt transformer and photocell/timer combo. I initially set the timer for a 4 hour turn off after dusk and it worked fine. Now the lights will not turn on for any of the timed selections. It will turn lights on if timer is set to on. Has anyone experienced this before?
Have you tried the universal reboot method (iow, unplugging the timer for half a minute and then plugging it back in)? I know you said it worked once but is there any chance the transformer photocell is exposed to too much light where it’s located (like maybe from an exterior light source? If you cover the photocell, you should be able to get it to turn on, btw.
