Davies Craig Digital Thermatic® Twin Fan Switch with 1/4"" NPT Thermal Sensor Kit with 35mm Inline Adaptor

\n \n \n

\n

The Digital Thermatic^® Fan Switch GEN II is the next evolution of Davies Craig's proven fan controller. This specific kit comes complete with a ¼" NPT Thermal Sensor and a 35mm Inline Adapter, offering a quick and highly reliable way to install the sensor directly into your top radiator hose.

\n

Superseding the popular 0435 model, the GEN II can manage 1 or 2 fans with smarter features and a faster response. Fan #1 activates at your set temperature, while Fan #2 activates just 5 seconds later for improved cooling response. Both fans switch off once the temperature drops 5°C below the set point.
