This provides direct, immediate control without affecting the programmed schedule.
Automatic Mode Programming (7-Day Schedule)
Automatic mode allows for a customized 7-day schedule, offering precise control over your connected devices. Select “AUTO” using the MODE button. The display will then prompt you to program on/off times for each day of the week. Utilize the selector knob to adjust the hour and minute for each event.
You can set multiple on/off cycles per day, tailoring the schedule to your specific needs. Confirm each setting with the “OK” button. The timer remembers these settings, automatically activating and deactivating your devices according to the programmed schedule. This mode provides convenient, hands-free operation, maximizing energy efficiency and convenience.
Random Mode Functionality
Random mode enhances security by simulating occupancy when you’re away. Activate it by pressing the MODE button until “RAND” appears on the display. This feature automatically turns your connected lights or devices on and off at varying, unpredictable intervals throughout the evening.
The timer utilizes a built-in algorithm to create a realistic lighting pattern, deterring potential intruders. No programming is required; the random function operates automatically once selected. This is ideal for vacation periods or extended absences. Random mode provides an added layer of security and peace of mind, making your home appear lived-in even when it’s not.
