The K4536SS and K4536SST photo controls are solid-state, locking-type, controls. Model K4536SS is a precision built, Dusk-to-Dawn Photo Control. Model K4536SST is similar but also designed to save energy while providing flexibility to accommodate special needs. It turns ON at dusk and OFF at pre-set time between 6 pm and 2 am. In the morning, it will turn ON again at a pre-set time between 4 am and 8 am and OFF at dawn. The fixed times are calculated based on the occurrence of sunrise and sunset. In case of a power failure, the photo control automatically resets its internal clock.
