We recommend using a manual motor controller with up/down switch for your motors. Shit can happen - no matter where you source your light dep kit. You can accidentally over-roll your blackout rolling bars, catch a garden hose, trellis netting, etc. With this system you can manually raise your rolling bars while watching for any potential errors. Then, if desired, automate your down function with a simple $10 timer to save time each day. Rarely do problems occur during the down phase.
