Water Management
Muslima Alia
Efficient water management is critical in both residential and commercial settings. Manual monitoring often leads to overflow, dry runs, and inefficient pump usage. Waltr C a smart automatic pump controller, addresses these challenges through automated pump control powered by real-time water level data. Designed for accuracy and reliability, this smart water level controller integrates seamlessly with your existing motor setup, enabling intelligent pump operation, wireless connectivity, and remote system access. The result—optimized water usage, reduced energy consumption, and minimal manual intervention.
What is Waltr C?
Waltr C is a fully automatic water pump controller that streamlines water supply management. It automates pumps connected to overhead and sump tanks, eliminating the need for manual checks. For smart, real-time operation, Waltr C pairs seamlessly with Waltr A, a radar-based water level sensor that transmits live tank data to the cloud.
This Pump controller is Compatible with both single-phase and three-phase motors, Waltr C is ideal for homes, apartments, offices, and industrial environments. It also integrates easily with common starter panels, including DOL, star-delta, multi-capacitor, and even without a starter panel also.
How Waltr C (automatic water pump controller) Works?
Waltr C operates as a cloud-connected, automatic pump controller that utilizes real-time tank level data from Waltr A, a radar-based water level sensor. When the water level in the tank falls below a predefined low threshold, Waltr A detects the change and transmits the data to the cloud server. Waltr C continuously polls this data and, upon identifying the low-level condition, issues a control signal to initiate pump operation.
Once the tank reaches the configured high-level threshold, Waltr A updates the water level accordingly. Waltr C receives this update and issues a stop command, terminating the pump operation. This automation logic eliminates the need for manual intervention and ensures efficient water resource management by running the pump only when required.
In addition to automated operation, manual control is available through the Waltr mobile application, enabling users to override or manually trigger motor control remotely as needed.
Pump Control Logic via NO Relays
Waltr C interfaces with the pump starter panel through two Normally Open (NO) relays, designed for low-voltage signal switching. These terminals are electrically isolated from the high-voltage motor circuit, enhancing system safety and simplifying integration.
When a low-level condition is detected, Waltr C activates the NO terminals, closing the relay circuit. This completes the control loop to the starter panel, initiating motor start-up.
Upon reaching the high-level threshold, Waltr C deactivates the NO terminals, opening the relay circuit and signaling the motor to shut down.
This relay-based control strategy ensures that motor switching is performed without direct contact with high-voltage lines, enabling safe, reliable, and energy-efficient pump automation.
Key Features of Waltr C
Waltr C is engineered to deliver intelligent and reliable pump control, extending far beyond the capabilities of conventional controllers. Designed for seamless integration and long-term performance, it brings automation, safety, and data-driven insights into your water management system.
Solid-State Relay (SSR) Switching: Equipped with a solid-state relay, Waltr C enables noiseless operation with minimal mechanical wear, ensuring high durability and extended lifecycle in demanding environments.
Automatic Pump Control: Based on real-time tank levels received from Waltr A, Waltr C automatically initiates and terminates pump operation, eliminating manual monitoring and ensuring consistent water availability.
Remote Operation via App: Users can monitor and control pump activity remotely using the Waltr mobile app, enabling on-demand operation and real-time status updates from anywhere.
Dry Run Protection: When paired with Waltr A, Waltr C can prevent dry run conditions by monitoring source tank levels or inflow anomalies, safeguarding the pump from damage.
Scheduled Timers and Daily Runtime Settings: Waltr C allows users to configure pump activation windows and limit daily run durations—ideal for systems where timed operation or power-saving schedules are essential.
Multi-User Access and Activity Logs: Supports multiple user profiles with shared access and maintains a detailed log of motor activity for improved traceability and maintenance planning.
Connectivity and App Integration
Waltr C leverages Wi-Fi connectivity for continuous data transmission and real-time system monitoring. Bluetooth communication is used exclusively during the initial provisioning process to securely configure Wi-Fi credentials. Once setup is complete, all data exchange occurs via the cloud.
The Waltr app (compatible with Android 5.0+ and iOS 10+) provides users with full remote access to pump and tank status. Through the app, users can view real-time water levels, monitor pump activity, and manually control operations when needed.
The system also issues push notifications for key events such as dry run detection, low-level alerts, overflows, and manual interventions. Historical logs and visual dashboards enable performance tracking and long-term trend analysis.
Installation and Compatibility
Waltr C is designed for professional installation and should be set up with the assistance of a qualified electrician. While not a plug-and-play device, its setup process is straightforward and well-documented. For safety and optimal performance, it must be installed indoors or within a starter panel enclosure, as the device lacks an IP rating for water or dust ingress protection.
Waltr C is compatible with a wide range of motor configurations, including:
Single-phase and three-phase motors
Borewell and submersible pumps
Starter panels such as DOL (Direct-On-Line), star-delta, multi-capacitor, and Grundfos relay-based systems
Note: Waltr C is not compatible with electronic digital starter panels or systems requiring direct integration with digital control circuitry.
Durability and Maintenance
Built with robust components and solid-state switching, Waltr C is designed to last between 5–7 years. Maintenance is minimal. A stable internet connection, a dry starter panel, and attention to app alerts are all you need to keep the system running smoothly.
Waltr C comes with a 1-year warranty, and the Waltr support team is available for quick help if needed.

Works Best with Waltr A (water level indicator)
Waltr C integrates seamlessly with Waltr A, a radar-based water level indicator. Waltr A transmits real-time tank data to the cloud, which Waltr C uses to automate pump operation based on predefined high and low thresholds.
Together, they deliver a fully automated, IoT-enabled water management system with live monitoring, control, and alerts—all accessible via the Waltr app.
However, Waltr C can also function independently. In the absence of Waltr A, users can manually operate the pump through the Waltr app from any location, maintaining control and flexibility without automation.
What Makes Waltr C Different?
Waltr C is more than a regular automatic motor controller. Its wireless app-based operation sets it apart from conventional systems. With radar-based automation through Waltr A, it provides intelligent pump control with smart alerts and insights.
Its solid-state relay ensures long life, silent switching, and electrical safety. The system sends motor status updates every 5 minutes, enabling detailed analytics and historical logs.
