This allows you to customize the duration based on your specific requirements. To simplify the setup process, we suggest connecting all the landscaping lights that need to be turned off simultaneously to the same transformer. Automatic Overload Circuit Breaker In the event that the LED display is off but the utility voltage is still present, it indicates a significant overload on the transformer. To prevent any potential damage, the automatic overload circuit breaker will automatically shut off the low voltage output of the power unit if the circuit becomes overloaded with too many fixtures. This feature ensures the safety and proper functioning of the transformer and connected fixtures. In the event that the power to the transformer is cut off, you can rest assured that your last setting will be remembered. This means that when you turn the power back on, the transformer will retain and restore your previous setting instead of resetting it. This convenient memory function allows for a hassle-free experience without the need to reconfigure the settings every time the power is interrupted.
