The level control is suitable for filling a tank or aquarium automatically. The level switch has to be mounted at the maximum water level of the tank and to be conducted with the BasiTechTM housing. After power supplying and connecting the refill pump of solenoid valve the green LED will flush. If the water level drops the BasiTechTM control activates the yellow LED and the output channel. The conducted pump refills the tank. If the level switch is reached the pump will stop.
Tip! If the level switch will fail, e.g. algae or other things stuck between float and axis, the system may be protected with a second level switch. This one should be mounted a little bit higher than the first one. Electrically it must be connected parallel. The unit will stop if one of the two level switches reaches the upper position.
You can use the unit for a external installed skimmer, too. If a skimmer is not controlled properly, too much wet foam will be produced and fill up the foam cup immediately. To prevent a water spill the BasiTechTM unit shut off the air pump of the skimmer or the water inflow pump of it. Therefore the level switch must be mounted into the skimmer foam cup.
