Figure 4.2.1: Overview of the six distinct operating modes available on the transformer for flexible lighting control.
4.2.1 Manual On/Off Mode
In this mode, you manually turn the lights on or off. Select 'ON' for continuous operation or 'OFF' to keep lights off.

Figure 4.2.2: Direct manual control allows users to switch landscape lights on or off as needed.
4.2.2 Auto On/Off (Dusk to Dawn) Mode
The photocell sensor automatically turns lights on when it gets dark (dusk) and off when it gets light (dawn). This mode requires the photocell sensor to be properly installed and positioned.

Figure 4.2.3: Smart automatic light management ensures lights activate at dusk and deactivate at dawn, optimizing energy savings.
4.2.3 Countdown Mode
Lights turn on at dusk and automatically turn off after a set duration of 2, 4, 6, or 8 hours. Use the UP (▲) and DOWN (▼) buttons to select the desired countdown duration.

Figure 4.2.4: Programmable timers allow lights to activate at dusk and shut off after a user-defined duration (2, 4, 6, or 8 hours).
4.2.4 Timer Mode (On/Off at Set Times)
Program specific ON and OFF times for your lights. This allows for a custom lighting schedule independent of ambient light conditions.
- Press MENU until 'TIMER' is selected.
- Press ENTER to set the ON time. Adjust hour/minute with UP (▲) and DOWN (▼) buttons, then ENTER.
- Repeat for the OFF time.
