This illustrates the typical installation method within an electrical panel, highlighting the device's compact form factor and how it integrates with other electrical components.
5. Operating Instructions
The GreenBlue GB114 features a rotary knob for time adjustment and a selector switch for operating modes.

Image Description: This image provides a clear front view of the GreenBlue GB114 Staircase Light Switch. It highlights the central rotary knob used for setting the time delay, ranging from 30 seconds to 10 minutes. Below the knob is a small toggle switch for selecting between continuous operation and timed automatic shut-off modes. The terminal connections are visible at the bottom.
5.1. Time Adjustment
Use the rotary knob on the front of the device to set the desired operating time. The available range is from 30 seconds to 10 minutes. Rotate the knob clockwise to increase the time and counter-clockwise to decrease it.

Image Description: A close-up view of the GreenBlue GB114's control panel. It clearly shows the rotary knob (labeled 02) for adjusting the time delay from 30 seconds to 10 minutes, and the mode selector switch (labeled 01) which allows selection between continuous light and timed operation. The terminal screws (labeled 03 and 04) are also visible at the bottom.
5.2. Operating Modes
The device features two operating modes, selected via the toggle switch:
- Automatic Shut-off Mode (Timer): In this mode, pressing a connected push-button switch will activate the lights for the duration set by the time adjustment knob. After the set time, the lights will automatically turn off. This is the standard mode for staircase lighting.
- Continuous Mode (Permanent ON): In this mode, the lights will remain continuously on, bypassing the timer function. This can be useful for extended periods of illumination, such as during cleaning or maintenance.

Image Description: This image shows a hand pressing a standard wall-mounted light switch. This action represents the user interaction that triggers the GreenBlue GB114 Staircase Light Switch, initiating the timed illumination sequence in a corridor or stairwell.
6. Maintenance
The GreenBlue GB114 Staircase Light Switch requires minimal maintenance. To ensure optimal performance and longevity:
- Keep the device clean and free from dust. Use a dry, soft cloth for cleaning.
- Do not use liquid cleaners or solvents.
- Periodically check terminal connections for tightness, especially after initial installation.
- Ensure the electrical panel remains dry and well-ventilated.
