Product Information

Full details

This Davies Craig LCD EWP & Fan Digital Controller is for automotive enthusiasts and mechanics seeking precise engine cooling management. Its key benefit is maintaining optimal engine temperature through automated control of electric water pumps and cooling fans, preventing overheating and improving performance. A potential caveat is the need for compatible Davies Craig components for full functionality. This controller offers a slimmer design with universal mounting and features a high-contrast LCD for real-time data, adjustable temperature settings, post-shutdown cooling, and self-diagnostic capabilities.

FAQs

Can I use this controller with any electric water pump and fan?

This controller is optimized for Davies Craig Electric Water Pumps (EWPs) and compatible electric cooling fans. While it might interface with other components, full functionality and performance are best achieved with Davies Craig products.

How do I adjust the target temperature?

The target temperature can be adjusted using the simple push-button system on the controller. Refer to the product manual for specific button sequences.

What does the flashing EWP logo on the screen mean?

The flashing EWP logo indicates that the water pump is operating in Pulse Width Modulation (PWM) mode, meaning its speed is being adjusted dynamically to provide the precise coolant flow required by the engine.

Will the controller continue to run the fan after I turn off the engine?

Yes, the controller is designed to operate the EWP and fan for up to three minutes after the ignition is switched off. This helps to circulate coolant and dissipate any residual heat, preventing hot spots.

How do I perform a self-diagnostic test?

The controller has built-in self-diagnostic functions that provide visual and audible warnings for various system issues. Consult the user manual for the specific procedure to initiate and interpret these tests.

What happens if the battery is disconnected?

The controller will store your last set target temperatures in its memory, so they will be retained when the battery is reconnected.

What is included in the 'With Fitting Kit' option?

The 'With Fitting Kit' includes the controller, three different mounting options, a wiring harness, a temperature sensor, an in-line sensor adaptor (fits 35mm hose), rubber adaptor sleeves for 38mm hose, hose clamps, and instructions.

Troubleshooting

Controller does not power on.

Check the vehicle's battery connection and ensure the wiring harness is securely connected to the controller and power source. Verify the voltage supply is within the acceptable range.

EWP or fan not operating.

Confirm that the EWP and fan are compatible Davies Craig components. Check all wiring connections for the EWP and fan. Refer to the self-diagnostic error codes displayed on the LCD screen for specific issues.

Inaccurate temperature readings.

Ensure the temperature sensor is correctly installed in the coolant hose and making good contact. Check the sensor wiring for any damage or loose connections. Perform a sensor self-test if available via the controller's diagnostic menu.

Controller displays a voltage warning.

Check the vehicle's charging system. If the voltage is too high or too low, it may indicate an issue with the alternator or battery. Address the vehicle's electrical system problem.

Coolant temperature does not reach the set target.

Verify the EWP is functioning correctly and circulating coolant. Check for any blockages in the cooling system. Ensure the thermostat is not stuck open. The controller might be reporting that the engine is not reaching the target, indicating a system performance issue rather than a controller fault.

Pros and Cons

Pros

  • Provides precise and automated engine cooling control.
  • Helps maintain optimal engine operating temperature for improved performance and longevity.
  • Advanced features like post-shutdown cooling and self-diagnostics offer enhanced protection.
  • Clear LCD screen provides easily readable real-time data.
  • Flexible mounting options accommodate various vehicle setups.
  • Stores user settings even when the battery is disconnected.

Cons

  • Primarily designed to work with Davies Craig Electric Water Pumps (EWPs) and electric fans, limiting compatibility with other brands.
  • Requires careful installation and understanding of engine cooling systems.
  • The fitting kit, while comprehensive, adds to the overall cost if purchased separately from the controller.
  • Advanced features may be overkill for users with simpler cooling needs.
  • Reliance on a functioning EWP and fan means failure in those components will impact the controller's effectiveness.

Setup, Compatibility & Care

Setup:

  1. Mount the Controller: Select one of the provided mounting options (mounting bracket, nylon mounting plate, or Velcro pad) and secure the controller in a suitable location, away from excessive heat and vibration.
  2. Connect Wiring Harness: Follow the included instructions to connect the controller to your Davies Craig EWP, electric cooling fan, and vehicle's power supply.
  3. Install Temperature Sensor: Use the provided adaptor to place the temperature sensor in a coolant hose. For 35mm hoses, use the in-line adaptor. For 38mm hoses, use the provided rubber adaptor sleeves.
  4. Set Target Temperature: Use the simple push-button system to set your desired engine operating temperature. The default is 85°C (185°F).
  5. Configure Fan Operation: The controller automatically regulates fan speed based on coolant temperature, but consult the manual for any specific fan wiring or configuration requirements.

Compatibility:

  • This controller is specifically designed to manage Davies Craig Electric Water Pumps (EWPs) and compatible electric cooling fans.
  • The fitting kit includes adaptors for 35mm and 38mm coolant hoses.

Care:

  • Keep the controller clean by wiping it with a slightly damp cloth. Avoid abrasive cleaners or solvents.
  • Ensure all electrical connections are secure and free from corrosion.
  • Periodically check coolant levels and the condition of hoses and wiring.
