We've purchased a VPT24-1PZ timer to drive the exterior lights on our building. A picture of the box is below.
The installation seems correct. When pressing the toggle cover on the timer switch the lights turn on and off.
I went through the process to set the timer into pro mode and set it up for astronomical timing. The process when correctly as per both the instruction sheet and a web video I found. However the timer is not switch the lights on and off at sunset and sundown. I set the switch during the day. When I came out after dark, the lights were not on. Below is a picture on the front of the switch is what I assume is operating mode. Based on what I've read and seen, this is correct. At the time indicated, I would assume the timer would be on. It isn't.
Is there something I'm missing? Does anyone need more pictures to diagnose the problem.
