DF-96D Automatic Water Level Controller 220V Pump Switch
Keep your water tank, pool, or reservoir at the perfect level — automatically. The DF-96D / DF-96DK Automatic Water Level Controller is a reliable 220V sensor probe switch that monitors liquid levels and starts or stops your water pump without any manual input. Built from durable ABS plastic and CE-certified, it's ideal for home water tanks, irrigation systems, drainage ponds, and more.
Made in Mainland China.
Why Choose the DF-96D Water Level Controller?
- Fully Automatic Operation – Sensor probes detect rising and falling water levels and trigger the pump on or off with no intervention needed.
- High-Current Capacity – Rated at 25A / 220V, compatible with most standard household and commercial water pumps.
- CE Certified – Meets international safety standards for electrical equipment.
- 4 Versatile Wiring Modes – Supports fill tanks (Model A), drainage ponds (Model B), dry-run protection (Model C), and dual-tank (upper/lower) control (Model D).
- Compact & Easy to Install – Slim 86 × 66 × 49 mm ABS housing fits standard wall boxes; color-coded probe wires (Red, Blue, Black, Green, Yellow) make setup straightforward.
- Saves Water & Energy – Prevents overflow and dry running by cutting power to the pump at the precise moment it's needed.

4 Probe Wiring Modes Explained
Model A – Single Tank Fill (Sink/Overhead Tank)
- A (Red) – Upper level: pump stops automatically when water reaches this probe.
- B (Blue) – Lower level: pump starts automatically when water drops below this probe.
- C (Black) – Common line; place at the bottom of the tank.
- D (Green) & E (Yellow) – Connected to C (Black).
Model B – Single Drainage Pond
- E – Upper level: pump starts automatically when water reaches this probe.
- D – Lower level: pump stops automatically when water drops below this probe.
- C – Common line; place at the bottom of the pool.
- A & B – Disconnected.
Model C – Dry-Run Protection
- C & D – Lower-level control points; if either probe loses water contact, the pump stops automatically, protecting against dry running.
- E & C – Short-connected.
- A & B – Disconnected.
Model D – Dual Tank (Upper & Lower Pool) Control
- A – Upper pool high-level: pump stops when water reaches probe A.
- B – Upper pool low-level: pump starts when water falls below probe B.
- C – Common line for both upper and lower pools.
- D – Lower pool low-level: pump stops when water falls below probe D.
- E – Lower pool high-level: pump starts (drainage begins) when water reaches probe E; disconnect E if this function is not needed.

Frequently Asked Questions
Q: What voltage does the DF-96D water level controller operate on?
A: The DF-96D Automatic Water Level Controller is designed for 220V AC power supplies and supports a rated current of up to 25A, making it compatible with most standard household and commercial water pumps at 220V.
Q: How many tanks or pools can the DF-96D control at once?
A: By selecting the appropriate wiring mode (Models A–D), the DF-96D can be configured to control a single fill tank, a single drainage pond, provide dry-run pump protection, or manage a dual-tank upper-and-lower pool system — all with the same unit.
Q: Is the DF-96D water level controller easy to install?
A: Yes. The controller uses color-coded sensor probe wires (Red, Blue, Black, Green, Yellow) that correspond to clearly labeled connection points. The compact 86 × 66 × 49 mm housing fits standard wall boxes, and the included instruction manual guides you through each of the four wiring models step by step.
Q: Will the DF-96D protect my pump from running dry?
A: Absolutely. Using Model C (dry-run protection) wiring, the controller monitors the lower-level probes and automatically cuts power to the pump when the water level drops below the set point, preventing the pump from operating without water.
