Usage Tips:Feature:1. DIGITAL THERMAL FAN SWITCH FOR 0444: Fan switch kit can be used in 12 or 24 volt applications(if you intend to operate 24V fans you will need to purchase standard 24V relays.)2. TEMPERATURE RANGE: The electric fan controller kit adjustable temperature range is 104 to 230(40 to 110), and can display Celsius or Fahrenheit degrees. The temperature is set by pressing the set button. (LED digital temp display, actual temp and set temp.)3. WORK SPEED: The adjustable fan controller set can operate 1 or 2 fans. The second fan(if applicable) will start after 10 seconds of fan 1 work. Operate in a hot manner, and also when the air conditioning is running. Circuit type is pre programmed micro controller4. STABLE PERFORMANCE: Digital heat sink fan switch kit is made of standard material, wear resistant and long lasting. Professional manufacturing bring long service life. Size is 3.75in x 2.6in x 2.2in. Suitable for single and dual fan applications5. INSTALLATION TIPS: The dual electric fan controller kit as supplied with a sensor designed to be placed between the vehicles heat sink fins, an adapter kit is required to allow the sensor to be fitted into a coolant hoseSpecification:Item Type: Digital Fans ControllerMaterial: ABSVoltage: 12VMaximum Touch Current: 40ACoil Resistance: 90Relay Setting: Dual relaySensor Wire Total Length: Approx. 142cm / 55.9in(switch wire approx. 112cm / 44.1in + sensor connector approx. 30cm / 11.8in)Speed: Single speed, second fan start 10 seconds afterApplication: For single and dual fan applicationsScreen Display: LED digital temperature display, actual temperature + set temperatureTemperature Display: Celsius or FahrenheitTemperature Setting: 40 to 110(104 to 230)Temperature Setting: KeyCircuit Type: Pre programmed microcontrollerSize: Approx. 9.5 x 6.6 x 5.6cm / 3.75 x 2.6 x 2.2in.Package List:1 x Digital Fan Controller2 x Screws2 x Terminals2 x Terminal Protectors3 x Washers2 x Adhesive Pads3 x AccessoriesNote:If this switch is used for EWP, it will not change the pump speed based on engine temperature but will turn the pump on and off at your set temperature. For EWP control, we recommend using part number 8002, which can manage for EWP and your thermostatic fan.
