5. Setup
Proper installation is crucial for the optimal performance and longevity of the Wilo HiControl 1.
5.1 Mechanical Installation
- Mount the HiControl 1 vertically in the discharge line of the pump, ensuring the flow direction arrow on the device matches the water flow.
- Ensure the device is installed in a frost-free location and protected from direct weather exposure.
- Use appropriate sealing materials (e.g., PTFE tape) on threaded connections to prevent leaks.
- Ensure there are no air pockets in the system after installation. Bleed the system thoroughly.
5.2 Electrical Connection
- Connect the pump's power cable to the designated terminals on the HiControl 1. Refer to the wiring diagram inside the terminal box cover.
- Connect the main power supply (230V AC/DC) to the input terminals of the HiControl 1.
- Ensure all connections are secure and properly insulated.
- Verify that the power supply is protected by a suitable circuit breaker and residual current device (RCD).
6. Operating Instructions
The Wilo HiControl 1 operates automatically once properly installed and powered.
6.1 Initial Start-up
- Ensure the pump and the entire hydraulic system are filled with water and free of air.
- Switch on the main power supply to the HiControl 1.
- The pump will start automatically and run for a few seconds to pressurize the system.
- Open a tap to draw water. The pump should start.
- Close the tap. The pump should continue to run for a short period (run-on time) and then stop.
6.2 Normal Operation
- When a tap is opened and water is drawn, the HiControl 1 detects the flow and starts the pump.
- When the tap is closed and the flow stops, the HiControl 1 detects the cessation of flow and stops the pump after a short delay.
- The integrated dry-running protection will stop the pump if no water is detected, preventing damage.
7. Maintenance
The Wilo HiControl 1 requires minimal maintenance. Regular checks can help ensure reliable operation.
- Visual Inspection: Periodically check the device for any signs of damage, leaks, or corrosion.
- Electrical Connections: Ensure all electrical connections remain tight and free from corrosion.
- Cleaning: Clean the exterior of the device with a damp cloth. Do not use abrasive cleaners or solvents.
- Frost Protection: In cold climates, ensure the device and associated piping are protected from freezing.
