DAVIES CRAIG digital twin fan switch (sensor 1/4" NPT) + 38 mm inline adapter, 0488

Description

The Digital Thermatic Fan Switch GEN II is the next evolution of Davies Craig's proven fan controller.

This kit comes complete with a ¼" NPT Thermal Sensor and a 38mm Inline Adapter, offering a quick and highly reliable way to install the sensor directly into your top radiator hose.

Superseding the popular 0438 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.

Features & versatility

• 38mm Inline Adapter: fits neatly into your 38mm ID top radiator hose, allowing easy sensor fitment without modifying engine components. It features two ¼" NPT ports (bung included if only one port is needed).
• Improved display & layout: larger, clearer LED display with °C / °F units and all wiring relocated to the rear for a cleaner installation.
• Advanced override control: dual manual override wires allow for independent fan control with selectable signal polarity (positive or negative).
• Enhanced durability: upgraded to an IP67 rating for superior dust and water protection.
• Expanded temperature range: adjustable from 5°C to 110°C (41°F to 230°F).
• 12V & 24V compatible: 12V standard, 24V with 24V relays.
