Automatic Water Level Control Relay with 3 Sensors – Electronic Regulator for Tanks, Reservoirs, and Pools

Automatic water level control relay with limit, adjustment, and integrated electronic sensor. Ideal for water level automation systems in tanks, reservoirs, pools, aquariums.

• Compatible with water tanks, pools, aquariums
• Includes 3 level probes – 5 meters each
• Operating mode: Manual / Automatic / Off
• Quick and intuitive installation in any pumping system

1. Installation for Automatic Filling of a Tank

See Figure 1 in the image gallery for a clear wiring diagram. The pump will start automatically when the water level drops below the lower limit and stop when the tank is full.

• A (red) – upper level: stops the pump
• B (blue) – lower level: starts the pump
• C (black) – common lower line
• D (green) & E (yellow) – connected to C

2. Installation for Automatic Draining of a Tank

See Figure 2 in the image gallery for example. The pump will start when the water level is high and stop when the level decreases.

• E – upper level: starts the pump
• D – lower level: stops the pump
• C – common line
• A & B – disconnected

3. Maintaining a Minimum Water Level

See Figure 3 in the image gallery for installation. The pump will automatically stop when the water level drops below the user-defined minimum point.

• C & D – low level control points
• E & C – short connection (bridge)
• A & B – disconnected

4. Automatic Control Between Two Tanks

See Figure 4 in the image gallery for the full diagram. Allows water transfer from a lower tank to an upper tank with automated control.

• A – upper level in upper tank: stops the pump
• B – lower level in upper tank: starts the pump
• C – common line for both tanks
• D – low level in lower tank: stops the pump
• E – high level in lower tank: starts the pump

Note: If activation at the upper level of the lower tank is not desired, point E can be disconnected.
