Davies Craig, Digital Thermatic Fan Switch With 1/4" NPT Sensor, DC-0445

The Davies Craig Digital Thermatic Fan Switch Kit is designed to provide precise, adjustable temperature control for Thermatic Electric Fans, EWP® electric water pumps, and competitor fans. This advanced switch monitors air temperature as it passes through the radiator with a sensor placed in the radiator fin section, or it can be placed directly into the coolant system using the optional Temperature Sensor Adaptor Kit (Part #317-DC-0409).

This versatile kit is compatible with 12V and 24V applications, offering a temperature range of 104ºF to 230ºF (40°C to 110°C), with a clear digital display showing the actual and set temperatures in Celsius or Fahrenheit. The system can run one or two fans, with the second fan (if applicable) starting 10 seconds after the first fan. It operates thermally and can also be triggered by air conditioning systems.

Key Features:

• Adjustable Temperature Range – Set temperature from 104°F to 230°F (40°C to 110°C).

• LED Digital Display – Shows the actual and set temperature, in Celsius or Fahrenheit.

• Compatible with EWP® and Thermatic Fans – Can control both fans and electric water pumps.

• Dual Fan Capability – Controls one or two fans, with a 10-second delay for the second fan.

• Relay Setup – Dual relay system for easy installation.

• Warranty: 1 year

Specifications:

• Max Voltage: 12 to 27V (For 24V, relays need to be changed, not supplied in kit)

• Max Current per Fan: 40A

• Relay Setup: Dual relay

• Speed Control: Single speed with 10-second delay for second fan

• Temperature Settings: 40°C to 110°C (104°F to 230°F)

Kit Contents:

• Digital Fan Switch (IP66)

• Thermal Sensor Probe

• Mounting Kit for Sensor Probe

• ¼ NPT Thermal Sensor (DC-0465)

• Red 6mm Ring Terminal

• Blue 6mm Ring Terminal

• Blue Wire Joiners (2)

• Instructions

Notes:

• If used with an EWP® electric water pump, this switch will turn the pump on and off at your set temperature but will not vary the speed based on engine temperature. For EWP® control, Part #8001 is recommended, as it can manage both the EWP® and Thermatic fans.

• The kit is sold in 12V configuration. For 24V applications, the relays need to be changed to 24V units, which are not supplied in the kit.
