Working principle:
1 ''Current'' digital tube: Display the current water level, display between 0-8, flash slowly
2 ''ON'' digital tube, Relay ON water level.
3 ''OFF'' digital tube, Relay OFF water level
4 Press the ''ON'' button, the number of the ''ON'' digital tube is adjusted between 1-8
5 Press the ''OFF'' button, the number of the ''OFF'' digital tube is adjusted between 1-8
 
''ON'' digital tube = ''OFF'' digital tube : Only water level display function (Relay does not work)
''ON'' digital tube < ''OFF'' digital tube : Automatic water supply (pumping water from outside to water tower)
''ON'' digital tube > ''OFF'' digital tube :Auto drain (drains water to the outside)
 
Example to illustrate how it works:
 
Only water level display function (Relay does not work)
When the numbers of the two digital tubes ON/OFF are the same, the relay does not work (only the water level display function)
Example 1:
Trigger the ''ON''button, set the ''ON''digital tube to 1;
Trigger the ''OFF''button,set the ''OFF''digital tube to 1.
 
Example 2:
Trigger the ''ON''button, set the ''ON''digital tube to 2;
Trigger the ''OFF''button,set the ''OFF''digital tube to 2.
 
Automatic water supply (pumping water from outside to water tower)
Fill the water tower automatically
 
Example 1:
The water supply starts when the water level is lower than 1, and stops when the water level is higher (or equal to) 7.
 
Trigger the ''ON''button, set the ''ON''digital tube to 1;
Trigger the ''OFF''button,set the ''OFF''digital tube to 7.
 
Example 2:
The water supply starts when the water level is lower than 2, and stops when the water level is higher (or equal to) 6.
Trigger the ''ON''button, set the ''ON''digital tube to 2;
Trigger the ''OFF''button,set the ''OFF''digital tube to 6.
Auto drain (drains water to the outside)
Automatic pumping from water tower
 
Example 1:
Draining starts when the water level is higher than (or equal to) 5, and stops when the water level is lower than 3.
Trigger the ''ON''button, set the ''ON''digital tube to 5;
Trigger the ''OFF''button,set the ''OFF''digital tube to 3.
Example 2:
Draining starts when the water level is higher than (or equal to) 4, and stops when the water level is lower than 3.
Trigger the ''ON''button, set the ''ON''digital tube to 4;
Trigger the ''OFF''button,set the ''OFF''digital tube to 3.
