DIGITAL THERMATIC FAN SWITCH WITH ⅛” NPT THERMAL SENSOR KIT

PART NO: 0448

Davies Craig designed Digital Thermatic Fan Switch Kit can be used with Thermatic Fans, EWP’s and competitors Fans.

This kit comes with two sensors to enable various fitment options:

Sensor 1: Temperature Probe (Air or Coolant  Fitment)

Sensor 2: ⅛ NPT Thermal Sensor Kit (Coolant Fitment Only)

Sensor 1: It senses air temperature as it passes through the radiator with the sensor placed in the radiator fin section or the sensor can also be placed directly into the coolant system in combination with a Davies, Craig Temperature Sensor Adaptor Kit (Part 0409) which is available from our store.

Sensor 2: The Thermal Sensor can be placed into the thermostat housing, engine block, or directly into the radiator. If you would like to install this sensor in the top radiator hose, It can also be used with Davies, Craig Temperature Sensor Adaptor Kit (Part 0409) which is available from our store.

It can run 1 or 2 fans and be used for 12 or 24 volt applications. It has an adjustable temperature range of 40ºC to 110ºC (104ºF to 230ºF) which can show Centigrade or Fahrenheit. Temp is set by pressing the set button.

• Fan #1 will start once the temperature reaches the set temperature.
• Fan #2 (if applicable) will start operation 10 seconds after fan #1 starts.
• The fan/s will operate until the temperature falls by 5°C below the set temperature.

Sensor Wire length:

• 142cm in total (Wire from switch 112cm plus sensor connector 30cm)
• Post 15-Dec-2021 = 320cm total (Wire from switch 290cm plus sensor connector 30cm)

*The sensor wire has been increased to 320cm from the 15-Dec-2021, batch date 2021
