Controller specification Applicable models It is suitable for water purifiers that obtain raw water from a tap water pipe, which means that the raw water must have sufficient pressure. Button function description The board is equipped with three key switches: select key, confirm key and strong punch key. The function description of each button is as follows: �8�4 Select key function: Press the first time to enter the setting mode; Press the first time, the English interface starts to flash, if you press the OK key at this time, the English interface is selected; Press the second time, the Chinese interface starts to flash, if you press the OK key at this time, the Chinese interface is selected; Press the third time, the first-stage filter element starts to flash, if you press the OK key at this time, the first-stage filter element time will be reset to zero; Press the fourth time, the second-level filter element starts to flash, if you press the OK key at this time, the second-level filter element time will be reset to zero; Press the fifth time, the third-level filter element starts to flash, if you press the OK key at this time, the third-level filter element time will be reset to zero; Press the sixth time, the fourth-level filter element starts to flash, if you press the OK key at this time, the fourth-level filter element time will be reset to zero; Press the seventh time, the fifth-level filter element starts to flash, if you press the OK key at this time, the fifth-level filter element time will be reset to zero; Press the eighth time to return to the state of the first press; After pressing the selection key, if you do not press the OK key or the selection key within 5 seconds, it will automatically exit the setting mode; �8�4 Confirm key function: Used to determine the setting content selected by the selection key; The selected setting content is automatically saved, and will not be lost next power-on; �8�4 Strong punch key: Only in the water production mode, you can press the strong punch key, press the strong punch key, the machine will automatically rinse for 90 seconds; Display function description �8.4 Whether Chinese characters are displayed or English characters is displayed, the user can set it by himself, and it will be stored and recorded after the setting, and there is no need to set it again next time when the power is turned on; �8.4 When the water shortage mark flashes, it indicates that the raw water pressure of the machine is too low; �8�4 The turning of the water making mark indicates that the machine is filtering water; �8�4 The flushing mark flashing indicates that the machine is backwashing the membrane; �8.4 When the full water mark is on, it means the machine is in full standby state; �8�4 The filter element life bars 1, 2, 3, 4, 5 indicate the use time of the 5-level filter element, and the display will be reduced by one grid over time; �8�4 The three small 8 characters on the left are used to display the TDS value of raw water; �8�4 The two big 8 characters on the right are used to display the TDS value of pure water; Control function description Flushing function 1. The RO machine is plugged in, the contents of the display are all lit, the buzzer beeps once, and the machine is forced to flush for 90 seconds; 2. Press the strong flush button, the machine will flush for 90 seconds; 3. Exit flushing for 30 seconds in the state of lack of water; 4. When the water is full, if the water production time is longer than 10 minutes, flush for 5 seconds; if the water production time is less than 10 minutes, the pressure is released for 10 seconds; 5. When the low-voltage switch is disconnected continuously for 60 seconds, it enters the water shortage mode; 6. Accumulated water production for 2 hours, automatic flushing for 30 seconds; 7. The flush mark flashes, the buzzer does not sound, the flush valve opens, the water pump opens, and the water inlet valve opens; 8. If the high-pressure switch is closed during flushing, the water production will be removed, and the remaining flushing will be completed after the water production is over; Water shortage 1. In the state of water production or flushing, the low-pressure switch is continuously turned off for 60 seconds and enters the state of water shortage; 2. The low-pressure switch is closed in the water shortage state and enters the flushing state; 3. Under water shortage, the buzzer will beep 10 times, The water pump stops, the water inlet valve is closed, and the flush valve is closed; Full state 1. If the high-pressure switch is turned on at the end of the flushing, it will enter the water full state; 2. If the high pressure switch is turned on during water production, if the water production time is longer than 10 minutes, flush for 5 seconds; if the water production time is less than 10 minutes, the pressure will be released for 10 seconds; then the water will be full; 3. When the high voltage switch is closed, it will exit the water full state and enter the water production state; 4. When the water is full, the water full mark will stay on, the buzzer will not beep, the water pump will stop, the water inlet valve will be closed, and the flush valve will be closed; Water state 1. If the high pressure switch is closed at the end of the flushing, it will enter the water production state; 2. When the high voltage switch is closed when the water is full, it will enter the water production state; 3. In the water production state, the water production mark turns, the buzzer does not sound, the water pump works, the water inlet valve opens, and the flush valve closes; Overhaul status 1. If the water is continuously produced for 6 hours and the water is not full, it will enter the maintenance state; 2. In the overhaul status, the overhaul mark is on, the buzzer keeps beeping, the water pump stops, the water inlet valve closes, and the flush valve closes; TDS description The three small 8s show the TDS of raw water, and the big 8s show the TDS of pure water. TDS value has been temperature corrected; Filter life description 5 timers record the service life of the filter element. The life of the filter element is determined by the start time of the water pump. Therefore, the flushing time and the water production time are counted as the filter element service life; automatic storage, power failure data is not lost; the user can manually change the filter element Clear the timer 5 timers correspond to 4 filter elements and one membrane of the water purifier; the maximum service life of the filter elements is set at the factory and cannot be changed by the user; With the passage of time, the filter element service life bar will decrease one by one. When it is reduced to zero, the buzzer will sound (in non-silent mode), prompting the user that the filter element has timed out, but it will not affect any functions such as machine water production; If the filter element is found to be expired, it will beep 3 times; each time the machine makes water, it will also beep 3 times to remind the user to replace the filter element, but the machine will not shut down. The filter time of the liquid crystal is 1.12500 minutes 2.21000 minutes 3.24000 minutes 4.96000 minutes 5.49500 minutes
