This product with part numbers 0444 and DC0444 is compatible with different fan models such as Thermatic Electric Fans and EWP. The sensor can be installed on the radiator fins or directly into the cooling system using an adapter kit.
The adjustable temperature range is from 104°F to 230°F (40°C to 110°C), and the temperature is shown on an LED digital screen in either Celsius or Fahrenheit, with adjustment possible using a set button.
This device works effectively when placed in the engine, functioning well in high temperatures and when the air conditioner is on. It can manage one or two fans efficiently, with the second fan starting 10 seconds after the first one. Please note that our kit is suitable for both 12V and 24V systems, but you will need to buy separate 24V relays for the 24V setup. Make sure to keep the switch away from heat sources like the exhaust manifold.
