Davies Craig DC-0444 Digital Thermatic Fan Switch Kit 12V/24V Single/Dual Fan Controller

The Davies Craig DC-0444 Digital Thermatic Fan Switch Kit is a precision electric fan controller designed to automatically manage single or dual electric cooling fans based on real-time temperature sensing. Compatible with Davies Craig Thermatic fans, Electric Water Pumps (EWPs), and most competitors' fans, this universal kit provides reliable, programmable cooling control without the need to cut into coolant hoses.

The included temperature probe mounts directly into the radiator fin section to sense air temperature as it passes through the core. Alternatively, the sensor can be placed directly into the coolant system when used in combination with the Temperature Sensor Adaptor Kit (Part #0409, sold separately). The LED digital display shows both actual and set temperatures simultaneously in either Celsius or Fahrenheit.

Key Features:

• Dual fan support — controls one or two fans; Fan #2 activates 10 seconds after Fan #1 to reduce electrical load at startup
• Wide adjustable temperature range — 104°F to 230°F (40°C to 110°C), set with a single push button
• 12V and 24V compatible — ships in 12V configuration; swap relays for 24V applications
• LED digital display — shows real-time temperature and user-set target temperature in °C or °F
• A/C override input — automatically activates fans when the air conditioning system is engaged; green wire can also be used as a manual override
• High-current dual relay setup — rated at 30A continuous per fan, 40A maximum per fan; includes 2 x 30A fuses and 2 x 40A relays
• IP66 ingress protection rating — protected against dust and high-pressure water jets
• Pre-programmed microcontroller — no complex configuration required
• Fans turn off automatically — both fans shut down once temperature drops 5°C (9°F) below the set point
• Compact housing — 3.75" x 2.6" x 2.2" (95 x 65 x 56 mm) for easy underhood mounting

Kit Includes:

• 1x Digital Thermatic Fan Switch / Controller
• 1x Temperature Probe
• 1x Temperature Probe Mounting Kit

• Max Startup Current: 60A
• Temperature Range: 104°F – 230°F (40°C – 110°C)
• Relay Setup: Dual relay
• Dimensions: 3.75" x 2.6" x 2.2" (95 x 65 x 56 mm)

Important Notes: The DC-0444 is not designed to vary the speed of Davies Craig Electric Water Pumps (EWPs). For full EWP and fan management, Davies Craig recommends part #8002. Do not cut or extend the sensor probe wiring, as this will interfere with the resistance signal and render the unit inoperable. For coolant direct-mount sensing, see part #0409 or #0465.
