Sensor Installation Details
Overhead Tank Connections
OH → High Level Sensor (Top of Tank)
OL → Low Level Sensor (Middle of Tank)
C → Common Sensor (Bottom of Tank)
Underground Tank Connections

C → Common Sensor (Bottom Level)
Working Function
When the overhead tank becomes empty, the controller automatically starts the motor — but only if water is available in the underground tank.
If there is no water in the underground tank, the controller will not allow the motor to start, protecting the motor from dry run and damage.
Once the overhead tank gets full, the controller automatically stops the motor to prevent water overflow.

The VENEX LLC 3M is a most reliable and easy-to-install automatic water level controller for three phase motor applications.
Manufactured by VENEX Electricals.

Note for Installation Without Underground Tank

If there is no Underground Tank and only a borewell with a single Overhead Tank is being used, then the Underground Tank sensors are not required.

In this condition, make a short link connection between:

UL

UH

Common (C)

All three terminals should be linked together using a wire jumper.

This bypass connection allows the controller to operate only with the Overhead Tank system and disables the Underground Tank sensing function.

With this setup:

The controller will work with only one overhead tank.

The motor will automatically start and stop according to the overhead tank water level.

Underground tank monitoring will remain inactive.

Introducing the VENEX LLC 1M Single Phase Water Level Controller — a fully automatic and reliable water level management system designed for both overhead and underground water tanks.

This model operates on Single Phase 230V AC power supply with a load capacity of 20 Amp. The controller is provided with Phase-Neutral Input and Phase-Neutral Output connections for easy installation. It includes both Auto OFF and Bypass modes for flexible operation according to user requirements.

The device is specially designed to prevent:

Overhead tank overflow

Dry run operation of motor/pump

The controller features built-in LED indications for:

Power ON

Motor ON

Overhead Tank Water Level

Underground Tank Water Level

Along with the controller, 6 Stainless Steel (SS) Sensors are provided:

3 sensors for Overhead Tank

3 sensors for Underground Tank

Sensor Installation Details :-

Overhead Tank Connections

OH – Overhead High Level

OL – Overhead Low Level

C – Common

Sensor Positioning:

Common (C) → Bottom of overhead tank

OL → Middle level of overhead tank

OH → Top/high level of overhead tank

Underground Tank Connections

UH – Underground High Level

UL – Underground Low Level

C – Common

Sensor Positioning:

Common (C) → Bottom of underground tank

UL → Middle level of underground tank

UH → Top level of underground tank

Working Function

When the overhead tank water level drops below the low level sensor, the controller automatically starts the motor — but only if sufficient water is available in the underground tank.

If water is not available in the underground tank, the motor will not start, protecting the pump from dry run damage.

Once the overhead tank becomes full, the controller automatically stops the motor, preventing water overflow and saving electricity.

Based on your description and the image provided, here is a professional product overview and technical specification for the **VENEX WLC 26 Automatic Water Level Controller**.
## **Product Overview: VENEX WLC 26
The **VENEX WLC26** is a high-performance, fully digital automatic water level controller designed for single-phase motor operations. It acts as an intelligent bridge between your water source and storage, ensuring your pump operates efficiently while staying protected from electrical and mechanical faults.
### **Key Features**
* **Dual Digital Display:** Real-time monitoring of both **Voltage** and **Current (Amperes)**.
* **Dual Tank Control:** Manages both the overhead tank (Upper) and the underground tank (Lower) simultaneously.
* **Sensor System:** Utilizes a 6-sensor system (3 for the upper tank and 3 for the lower tank) for precise level detection.
* **Auto/Manual Modes:** * **Auto:** Fully autonomous operation based on water levels.
   * **Manual:** Allows the user to control the pump via physical switches.
* **Fault Indicators:** Dedicated LED indicators/display codes for faults like Overload, Dry Run, and Voltage fluctuations.
### **Technical Specifications**
| Feature | Specification |
|---|---|
| **Model** | WLC26 |
| **Phase** | Single Phase |
| **Motor Capacity** | Suitable for 1 HP to 3 HP motors |
| **Current Capacity** | 20 Amperes |
| **Input Display** | Digital Voltage & Ampere Meters |
| **Level Indications** | Visual indicators for Upper and Lower tank levels |
### **Advanced Protection Suite**
The WLC26 is equipped with a comprehensive protection system to increase the lifespan of your motor:
* **Overload Protection:** Shuts down the motor if it draws excessive current.
* **High/Low Voltage Protection:** Prevents motor burnout during power surges or brownouts.
* **Dry Run Protection:** Automatically turns off the pump if the source tank is empty or if no water is flowing.
* **Cyclic Timer:** Allows for scheduled operation.
* **Unbalance Protection:** Monitors electrical stability.
### **Installation Tip: Single Tank Usage**
If you wish to use the controller **only for the Upper Tank** (Overhead Tank) and bypass the Lower Tank (Underground) monitoring, follow these steps:
1. Locate the terminals for the lower tank sensors, typically labeled **UL (Underground Low)**, **UH (Underground HIGH)**, and **COM (Common)**.
2. Use a small jumper wire to **short/connect these three terminals together**.
3. Once shorted, the controller will "think" the lower tank is always full, allowing the overhead tank to operate automatically without interference.
### **Manufacturer**
This product is manufactured by **Venex Electricals**, known for robust industrial and domestic water management solutions.
