Davies Craig DC0485 Digital Thermatic Fan Switch for Twin Fans with 1/4" NPT Thermal Sensor Kit with 35mm Inline Adapter.

Digital Thermatic® DC0485 - GEN II Fan Switch with ¼" NPT Sensor and 35mm In-line Adaptor

The Digital Thermatic® GEN II Fan Switch is the next evolution of Davies Craig's proven fan controller. This kit includes a ¼" NPT thermal sensor and a 35mm in-line adaptor, allowing for quick and reliable sensor installation directly into the upper radiator hose.

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

Features & Versatility

35mm In-Line Adaptor: Perfectly fits 35mm ID upper radiator hose, making sensor installation easy without modifying engine components. Features two ¼" NPT ports (blanking plug included if only one port is needed).

Improved Display & Design: Larger, clearer LED display with °C/°F units and all wiring relocated to the back for a cleaner installation.

Advanced Override Control: Dual manual override wires allow independent fan control with selectable signal polarity (positive or negative).

Enhanced Durability: IP67 rated for superior dust and water protection.

Extended Temperature Range: Adjustable from 5°C to 110°C (41°F to 230°F).

12V & 24V Compatible: 12V standard; simply swap to 24V relays (part no. 10534, sold separately) for 24V systems.
