Digital Radiator Fan Controller with Adjustable Temperature Range for Automotive Cooling Systems

This digital radiator fan controller is designed for automotive cooling applications and operates on 12V or 24V electrical systems.It supports both air and coolant temperature sensing.For air temperature monitoring, the is installed in the radiator fin section near the hot coolant inlet to measure airflow temperature, with an adjustable range of 40°C to 110°C (104°F to 230°F).For coolant temperature sensing, the can be integrated directly into the coolant system using a Temperature Adaptor Kit (Part 0409), typically installed in the radiator return hose.The unit includes a dual relay setup, supporting single or dual fan configurations with a 10-second delay before activating the second fan.An LED digital display shows both current and set temperatures, with selectable units in Celsius or Fahrenheit.Temperature settings are adjusted via push buttons.Package includes one digital thermatic fan switch kit.
