New to this site and although I searched for an answer, I apologize if one is here as I could not find an answer. I have an Intermatic ET90115CE programmable timer for parking lot lights control. I have been searching for a timer that I can use for shutting down the lights earlier than the scheduled time. The signal or relay would need to be a 1/2 - 1 second on or closed contact pulse, then return to an off or open contact state. This would allow the ET90115CE to resume it's normal programmed schedule. What I would like to do is have a circuit that when activated gives me a preset time of approximately 10-30 minutes to get to my vehicle before the lights go off. The reason for wanting this is the lights are set to go off each night at 10:30PM, but once in a while we might leave earlier than the time scheduled. Thus saving us a good amount on our electricity usage. Any help or suggestions would be appreciated.
