Feature: 1. DIGITAL THERMAL FAN SWITCH: Fan switch kit compatible with 12V or 24V applications. For 24V fan operation, standard 24V relays must be purchased separately. 2. TEMPERATURE RANGE: Electric fan controller features an adjustable temperature range of 104°F to 230°F (40°C to 110°C). Displays both actual and set temperatures in Celsius or Fahrenheit. Temperature is set using the control button. Includes LED digital temperature display. 3. OPERATING MODE: Fan controller supports one or two fans. If two fans are used, the second fan activates 10 seconds after the first. Operates based on temperature and activates when the air conditioning is running. Utilizes a pre-programmed microcontroller circuit. 4. DURABLE CONSTRUCTION: Digital fan switch kit constructed from standard ABS material. Designed for durability and long service life. Suitable for single and dual fan setups. Dimensions: 3.75 x 2.6 x 2.2 inches (9.5 x 6.6 x 5.6 cm). 5. INSTALLATION: Includes a temperature sensor designed to be placed between radiator fins. An adapter kit is required to install the sensor into a coolant hose. Specification: Item Type: Digital Fan Controller Material: ABS Voltage: 12V Maximum Load Current: 40A Coil Resistance: 90Ω Relay Configuration: Dual relay Sensor Wire Length: Approx. 142cm (55.9in) (controller wire: 112cm / 44.1in, sensor connector: 30cm / 11.8in) Speed Control: Single speed; second fan starts 10 seconds after first fan Application: Compatible with single and dual electric fan systems Display: LED digital display showing actual and set temperature Temperature Units: Switchable between Celsius and Fahrenheit Temperature Range: 40°C to 110°C (104°F to 230°F) Setting Method: Button control Circuit Type: Pre-programmed microcontroller Dimensions: Approx. 9.5 x 6.6 x 5.6cm / 3.75 x 2.6 x 2.2in Package List: 1 x Digital Fan Controller 2 x Screws 2 x Terminals 2 x Terminal Protectors 3 x Washers 2 x Adhesive Pads 3 x Accessories Note: When used with an electric water pump (EWP), this switch will turn the pump on and off at the set temperature but does not adjust pump speed based on engine temperature. For variable speed EWP control, consider part number 8002, which supports both EWP and fan control.
