Basic operating specifications
Function Detailed operation
1.
Initial power
supply
When the power is supplied for the first time, the indicator LED blinks twice (at 0.2
second intervals), then blinks slower (at 1 second interval) and then works normally
according to the input and output conditions.
2.
Water level
and valve
control
1) Water level control
- The water level is controlled by the low water level sensor, the full water level
sensor and the overflow sensor.
2) Water level sensor confirmation delay
- After supplying power, the signal from the water level sensor is ignored for
approximately 3 seconds while waiting for the stabilization of the sensor
operation.
- The low and full water level sensors only work when the corresponding water
level is detected for approximately 3 seconds.
- The overflow sensor only works when a water overflow is detected for
approximately 20 seconds or a non-overflow is detected for approximately 3
seconds.
3) Feed valve control
- Low water level status: The feed valve is immediately turned on and the water
filtration is started.
- Mid water level status: The feed valve is turned on immediately and the water
filtration is started.

However, if the water level changes from full to mid level, the feed valve is
turned on in approximately 15 minutes.
- Full water level status: The feed valve is turned off to cut the water supply.

However, if the water level changes from mid to full, the feed valve is
turned off after approximately 3 seconds.
4) Nos valve control
- If the overflow sensor detects a water overflow for 20 seconds continuously,
the Nos valve is turned on and the water supply is cut off.
- The low water level sensor returns to normal.
