Davies Craig Digital Thermo Fan Switch

The Davies Craig 0444 Digital Thermo Fan Switch can be used to control operation of all types of 12 volt electric thermo fans and water pumps. It senses air temperature as it passes through the radiator and has an adjustable temperature range of 400C to 1100C. The temperature sensor is placed in the radiator fin section as close to the hot coolant inlet as possible so there is no need to cut any coolant hoses. The controller is operated thermally and also when the air conditioning is switched on. The setpoint temperature for the fans is simply set by pressing the set button on the controller and can be read on the LED display. The option is available to run 2 fans, with the second fan starting 10 seconds after the first fan has started.
