The SunLight is a SunSaver Gen2 controller that includes a rotary switch which allows it to turn on the loads after dusk for 2, 4, 6, 8, or 10 hours.
One option turns loads on at dusk then off and on again before dawn. In this configuration, you can choose the following settings (in hours): 3/off/1, 4/ off/2, or 6/off/2. “On” from dusk to dawn is also possible.
A test button turns light(s) on for five minutes.
