Product Information

Full details

This adaptor kit is for users of Davies Craig digital thermatic Electric Water Pump (EWP) and fan switch kits (0444/0500) who need to replace a 5mm probe-type sensor with a screw-in temperature sensor. The key benefit is the flexibility to use screw-in sensors in 1/4" NPT or 1/8" NPT ports. A caveat is that it specifically replaces the 5mm probe sensor and requires compatible EWP/fan switch models.

Extended Product Information

FAQs

What specific Davies Craig units is this adaptor compatible with?

This adaptor kit is compatible with the Davies Craig 0444 Digital Thermatic EWP / Fan Switch and the 0500 Digital Gauge Thermatic Fan / EWP Switch Kit.

Does this kit include a new temperature sensor?

No, this kit is an adaptor only. It allows you to use a screw-in type sensor with your existing Davies Craig EWP/fan switch kit, replacing the standard 5mm probe sensor.

What size threaded ports can this adaptor fit?

The adaptor is designed to fit into both 1/4" NPT and 1/8" NPT threaded ports.

What is the length of the included cable?

The adaptor includes a 30cm length of cable to connect the sensor to the EWP / Fan switch.

Can I use this adaptor with other brand fan controllers?

This adaptor is specifically designed for Davies Craig 0444 and 0500 EWP/fan switch units. Compatibility with other brands is not guaranteed.

How do I ensure a secure fit in the engine port?

Use appropriate thread sealant (like PTFE tape or pipe dope) on the adaptor's threads before screwing it into the NPT port. Tighten securely but avoid overtightening.

Troubleshooting

Temperature reading is inaccurate or not showing.

Verify the sensor is correctly screwed into the adaptor and the adaptor is securely installed in the port. Check the 30cm cable connection at both the adaptor and the EWP/fan switch for looseness or damage. Ensure the sensor itself is functioning correctly.

Adaptor does not fit the port.

Confirm the port is indeed 1/4" NPT or 1/8" NPT. Ensure no thread sealant or debris is obstructing the threads. If the port size is different, this adaptor will not be suitable.

EWP / Fan switch is not responding to temperature.

Double-check all electrical connections to the EWP/fan switch and ensure the temperature sensor is properly connected via the adaptor cable. Refer to the EWP/fan switch manual for further troubleshooting.

Cons

  • Only compatible with specific Davies Craig digital thermatic EWP / fan switch models (0444/0500).

Setup, Compatibility & Care

Compatibility: Ensure your existing Davies Craig unit is either the 0444 Digital Thermatic EWP / Fan Switch or the 0500 Digital Gauge Thermatic Fan / EWP Switch Kit. The adaptor is designed to fit into 1/4" NPT or 1/8" NPT ports.

Setup:

  1. Disconnect the power to your EWP/fan switch.
  2. Remove the existing 5mm probe sensor from your Davies Craig unit.
  3. Screw the adaptor into the designated 1/4" NPT or 1/8" NPT port.
  4. Connect the temperature sensor (purchased separately or from your existing kit) to the threaded end of the adaptor.
  5. Connect the 30cm cable from the adaptor to the corresponding input on your Davies Craig EWP / Fan switch.
  6. Reconnect power and test the system.

Care:

  • Regularly check the connection for tightness to ensure accurate readings.
  • Keep the threaded connection clean from debris.
  • Inspect the cable for any signs of damage.
