Checking the function of the drinking water top-up process
Prerequisite:
The power plug is connected, the LED "Power" is lit and the level sensor is located in the water.
How to proceed:
• Take the level sensor out of the water. Result: After approx. 10 s (switch-on delay) the solenoid valve opens. Drink-
ing water is added and the LED "Open" is lit.
• Immerse all level sensor electrodes in the water. Result: After approx. 10 s (switch-off delay) the solenoid valve
closes. Drinking water top-up has been completed and the LED "Close" is lit.
Setting the sensitivity of the level sensor
A change in the conductivity of the water (e.g. due to chemical additives) may make it necessary to adjust the sensitiv-
ity of the level sensor.
Prerequisite:
• The power plug is connected.
• The level sensor electrodes are either immersed in the pond or in a container filled with water from the pond.
How to proceed:
• Remove the transparent cover from the level control unit (see chapter "Mechanical installation")
• Turn the sensitivity regulator "Sens" to the left-hand stop.
Drinking water top-up is activated and the LED "Open" is lit.
• Slowly turn the sensitivity regulator "Sens" clockwise (to the right) until drinking water top-up is deactivated and the
LED "Close" lights up.
• Turn the sensitivity regulator approx. 1 mm further clockwise in order to avoid malfunctions due to changes in the
conductivity of the water.
• Replace the transparent cover and screw tight.

Display / function
Drinking water top-up process has been completed
Drinking water top-up process is active
Power supply connected
Sensitivity regulator for setting the sensitivity of the level sensor
Cause
Power supply interrupted
Current supply to the solenoid valve interrupted
Connection of the level sensor to the level control unit interrup-
ted
Level sensor transmits incorrect values
Sensitivity of the level sensor too low
Solenoid valve defective
Pond is losing water through a leak
Remedy
Check the connection of the level control unit to
the mains
Check the connection of the level control unit to
the solenoid valve
Check the connection of the level control unit to
the level sensor
Check the positioning of the level sensor
Clean the electrodes of the level sensor
Increase the sensitivity setting of the level
probe
Send solenoid valve to an OASE dealer for re-
pair
Check pond for leaks
