The Digital Thermatic Fan Switch Kit by Davies Craig is the smart way to manage your cooling system. Designed for Thermatic Electric Fans, EWP® pumps, and competitor models, it gives Kiwi drivers precise temperature control to keep engines running at their best.
With an adjustable range from 40°C to 110°C, this kit lets you set the ideal operating temperature for your vehicle. The LED digital display shows both actual and set temps in Celsius or Fahrenheit, making monitoring simple and accurate.
Compatible with 12V and 24V applications (relay swap required for 24V), the kit can run one or two fans, with a built-in 10-second delay for the second fan. It also integrates with air conditioning systems, ensuring optimal cooling performance in all conditions.
