1. Pure Light-Controlled Mode

　　When sunlight is absent, the light intensity drops to the activation point. After a 10-minute delay, once the controller confirms the start signal, it activates the load according to the preset parameters, and the load begins operating. Meanwhile, when sunlight returns, the light intensity rises back to the activation point. Solar energy controller Delay for 10 minutes to confirm the shutdown signal, then turn off the output, and the load will stop operating.

　　2. Light-controlled + Time-controlled Mode

　　The startup process is identical to pure light control. When the load reaches the set time, it will automatically shut down; the setting range for this time is 1 to 14 hours.

　　3. Manual Mode

　　In this mode, users can control the load’s on/off state—whether it’s daytime or nighttime—simply by pressing a button. This mode is designed for specific loading scenarios or during debugging periods.

　　4. Debugging Method

　　For system debugging, the load is switched off when a light signal is present and turned on when no light signal is detected, making it easier to verify the correct installation of the system during setup and debugging.

　　5. Normally Open Mode

　　The power-on load remains continuously in the output state; this mode is ideal for loads requiring 24-hour power supply.

　　How to set up Solar energy controller

　　First, press and hold the button for more than 3 seconds—the digital display will start flashing, signaling that the system has entered adjustment mode. To exit this mode, simply release the button. Each time you press the button afterward, the displayed number on the digital tube will increment by one, cycling through all possible digits until it matches the number corresponding to the mode you’ve selected from the table. Once the digital display stops flashing—or if you press the button again for 3 seconds or longer—the setup is complete. (Refer to the attached modulation schedule for detailed mode descriptions.) **Mode Description:** Pure Light Control (0): When no sunlight is detected, the light intensity drops to the activation threshold, and the controller delays for 10 minutes to confirm the start signal. Based on the configured load parameters, the connected device begins operating. Conversely, when sunlight returns and the light intensity rises above the activation threshold, the controller waits another 10 minutes to verify the shutdown signal before turning off the output, causing the connected device to stop working.
