Photocell switch – Unwanted behavior
I just bought an inexpensive photocell switch, an Intermatic KC4121C. I was frustrated to discover that when you energize the device, it begins operating by first supplying power to its connected load (an outdoor lamp) for a minute or so, then it goes into a normal operation mode and either switched the load off if it registers enough daylight, or leaves the load switched on if it’s dark.
I was trying to obtain a photocell switch that would only supply power to its load device if it was dark out, and never when it’s daylight. I have an outdoor light that I want to have turn on when the sun goes down, and turn off at 7:00pm, every day. My plan was to use a timer and the photocell switch together to accomplish this. I wanted to use the timer to turn on power to the photocell switch at noon each day, and then cut power to it at 7:00pm. What I want to avoid is having the photocell switch turn on the outdoor lamp at noon for that first minute or so, every day, before going into normal operation mode and shutting the lamp off again, until sunset or 7:00pm, whichever comes first (depending on the length of daylight for the time of year it is).
Does anyone know of a photocell switch that doesn’t have this unwanted initial power up routine built into it? I just want one that can be energized during daylight hours, that does nothing at that point but then be ready to switch on its load when the sun goes down.
Thanks for any ideas or feedback anyone has to share 🙂
