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). It can be used for 12 or 24* volt applications and has an adjustable temperature range of 104degF to 230degF (40degC to 110degC) 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 operates thermally; also when the air conditioning is in operation.Specifications: Max voltage: 12 to 27V (For 24V, relays need to be changed, not supplied in kit)Max current: 40A per Fan Relay setup: Dual relayCircuit type: Pre-programmed micro controllerOutput wires: Batt + Batt - IGN, AC Clutch, Fan #1, Fan #2 Thermistor ProbeDimensions: 3-3/4" (95mm) x 2-9/16" (65mm) x 2-3/16" (56mm)*NOTICE: The unit is NOT WaterProof. 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 control, consider #8001 which can manage both the EWP and your Thermatic Fans. This fan will operate until the temperature falls by 5degC below the set temperature. Review: Don’t use the solder and shrink connectors and it’ll last. - So, ordered this unit 06/2022 to drive the double Maradyne fans installed on my F150. It has survived 3 summers of hard towing and 100k before the connections on the fans failed and melted the unit. A couple of the LEDs were failing on it, but the unit still worked fine. Buying another, money well spent and the unit failed because of the faulty solder and shrink connects, not because the unit was faulty. I have a second one that drives the Maradyne fans on my Z car and it still works perfectly and that unit is 6 years old. I have moved away from using the solder and shrink connectors and returned to just soldering and then heat shrinking the connections; the solder that comes in the solder and shrink is subpar and will fail after a couple of years, as I found out. Review: Good find - I needed a controller for a customers Jeep that a previous shop wired 2 electric fans to 1 relay that was wired to a key on power source and no controller. They just ran as long as the key was turned on and caused the relay and connector to melt, and the alternator was struggling to keep up. Going through reviews online this seemed like a good find. Straight forward install. Works as it's supposed to. I chose this controller because it used 2 relays to turn on the fans. ## Features - Mounts in Engine - Operate 1 or 2 fans - 12 & 24 Volt Configuration - Adjustable 104°F to 230°F - digital display can show Centigrade or Fahrenheit - Can be used with Thermatic Electric Fans, EWP's and similar models.

This controller is 1/2 the price and works perfect the controller is easy to set with the display..you set your temp and both fans work as described in the directions. The display also shows real time temperate and is within 2 degrees of both temp gauges in the car. this works fantastic i will always use these controllers from now on....thanks Australia ! ## Frequently Bought Together - Davies Craig Digital Thermatic Fan Switch Kit #0444 - Fan Mounting Kit, Mellbree 2-Pack Electric Radiator Fan Mounting Kit Compatible for Electric Cooling Fan and Transmission Cooler - Mishimoto Race Line, High-Flow Fan, 16" Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/46724419-digital-thermatic-fan-switch-kit-0444](https://www.desertcart.co.uk/products/46724419-digital-thermatic-fan-switch-kit-0444) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-02*
