This Digital Thermatic Fan Switch Kit can be used with Thermatic Electric Fans, EWP's and competitors Fans.

It senses air temperature as it passes through the radiator with the sensor placed in the radiator fin section or the sensor can now also be placed directly into the coolant system in combination with a Temperature Sensor Adaptor Kit (Part # 317-DC-0409).

Can be used for 12 or 24* volt applications and has an adjustable temperature range of 104ºF to 230ºF (40°C to 110°C) which can show Centigrade or Fahrenheit. Temp is set by pressing the set button. It can run 1 or 2 fans. The second fan (if applicable) will start 10 seconds after Fan #1 runs. It operated thermally & also when the air conditioning is in operation.

*Note: if using this switch for use with our EWP's, it will not vary the speed of the pump in response to engine temperature but rather turn the pump on and off at your set temperature. For EWP (Electric Water Pump) control, we would recommend part number 8001 which can manage both the EWP and your Thermatic Fans.

*Note: Kit sold in 12 volt configuration, for 24 volt application, you will need to change the two relays with 2 x 24 volt units which are not supplied in the kit.
