2.Set up timing period and duty cycles for auto recycling:

BRT-482 can automatically start recycling at preset time. Up to three recycling timing periods can be set up. Within each timing period up to five different duty cycle periods can be set.

Timing periods:

2.1 Set up the On time for timing period: Press and hold the "Timer" button for 3 seconds until the hour display starts to flash to enter timing period setup mode. Press "◀" or "▶" to adjust the hours (holding down "◀" or "▶" will adjust the hours quickly). Press the "ALLOFF" button the minute display starts to flash; press "◀" or "▶" to adjust the minutes (holding down "◀" or "▶" will adjust the minutes quickly); and

2.2 Set up the Off time for timing period: Once the On time for a timing period is set up press the "ALLOFF" button to set the Off time of the timing period. The hour display starts to flash and the right lower corner of the display shows “CL”. Press "◀" or "▶" to adjust the hours (holding down "◀" or "▶" will adjust the hours quickly). Press the "ALLOFF" button the minute display starts to flash; press "◀" or "▶" to adjust the minutes (holding down "◀" or "▶" will adjust the minutes quickly);

Once the timing period is set up proceed to set up the duty cycles. The longest available cycle time is 90 minutes and the shortest available cycle time is 5 seconds.

Duty cycles:

2.3 Press the "Timer" button to set the first On cycle time of the timing period. The minute display starts to flash and the left upper corner of the display shows “on1”. Press "◀" or "▶" to adjust the minutes (holding down "◀" or "▶" will adjust the minutes quickly). Press the "ALLOFF" button the second display starts to flash; press "◀" or "▶" to adjust the seconds (holding down "◀" or "▶" will adjust the seconds quickly); and

2.4 Once the first On cycle time for a timing period is set up press the "ALLOFF" button to set the first Off cycle time of the timing period. The minute display starts to flash and the left upper corner of the display shows “off1”. Press "◀" or "▶" to adjust the minutes (holding down "◀" or "▶" will adjust the minutes quickly). Press the "ALLOFF" button the second display starts to flash; press "◀" or "▶" to adjust the seconds (holding down "◀" or "▶" will adjust the seconds quickly);

Up to five different On cycles and 5 different Off cycles can be set up for each timing period in sequence. Repeat 2.3 and 2.4 to set up more cycles as desired.

Once the first timing period and its duty cycles are set up proceed to set up the On/Off time and On/Off cycles for the second timing period.

Once all the timing periods and their duty cycles are set up press and hold the "Timer" button until clock display stops flashing. The settings are saved. If there is no button operation for 15 seconds the settings will be automatically saved as well.

3.Manually triggered recycling:

BRT-482 can also start recycling anytime by pressing the “On” button. The duty cycle periods need to be set first by the steps as follows:

3.1 Right after setting up the clock time in step 1.2 press “Clock” button to enter manual recycling setup mode;

3.2 Follow step 2.3 and step 2.4 to set duty cycle periods as desired. Up to five different On cycles and 5 different Off cycles can be set; and

3.3 Once the duty cycles are set up press and hold the "Timer" button until clock display stops flashing. The settings are saved. If there is no button operation for 15 seconds the settings will be automatically saved as well.

The recycling process can be stopped anytime by pressing the “Off” button.

Delete settings

All the saved settings can be deleted by changing the settings to “--:--” by following the steps above.

BRT-481 timer socket and BRT-481B timer sockets are used for automatically turning on and/or turning off various loads such as fans lights appliances or other kinds of electrical equipment. They are perfect for saving energy and bringing convenience and safety to our daily life and work.

They have wide applications at various locations such as homes schools laboratories hospitals offices etc. The typical application scenes include:

Schools: Automatically ring the bells according to a fixed timetable to relieve manual intervention.

Hospitals or Laboratories: Automatically turn on and turn off UV disinfection equipment to isolate operators from harmful UV exposure.

Farms: Automatically turn on or turn off breeding equipment or lighting equipment for animals.
