Used for controlling the tank level via float (and via long cable) with adjustable delay timer for relay activation.

Connected with a ball-type float.

• Prevents frequent and unnecessary starting of a pump due to fluctuations that may occur on the tank's surface.
• The relay is triggered when the tank level is low (float contact is short-circuited) after the adjustable delay.
• The relay is deactivated when the tank is full and the float contact is open.
