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

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.
