Wall Mounted Digital Kl-233 Level Controller

The electronic level controller with 2 sensors automates aquarium water top-off. It includes two float switch sensors for safety: one triggers the feed pump to maintain the desired water level, while the second ensures overflow protection and prevents the pump from running dry. The controller can be used in three modes:
1. Mode A-1: Turns on the power supply if the sump water level is low and there is enough water in the storage tank. Turns off if the sump water level is high and the tank lacks water.
2. Mode A-2: Turns on when the sump water level drops below the set level, and off when it rises above.
3. Mode B: Turns on when the level falls below float sensor 1's minimal level and off when it rises above float sensor 1's set point. Float sensor 2 serves as a backup.
4. Mode C: The power supply turns on when both sensors detect the water level below the minimum and stops when it rises above the maximum level of both sensors.
