Your cart is empty. Digital Thermatic Fan Switch
Mounts in Engine Compartment
Adjustable 104degF to 230degF
12 & 24 Volt Configuration
This Digital Thermatic Fan Switch Kit can be used with Thermatic Electric Fans, EWP, and similar models. 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 relay
Circuit type: Pre-programmed micro controller
Output wires: Batt + Batt - IGN, AC Clutch, Fan #1, Fan #2 Thermistor Probe
Dimensions: 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.

I have no complaints. Plugged in to a 77 thunderbird. 400 engine. Dialed in the fan temps and they work as designed. Have not hooked up the AC actuation circuit yet but I’m doubting it will be any different

This item was purchased to replace an existing switch, and it was very easy to install

Fans wouldn't cut on until car was overheating. This kit is incredible. Everything you need for stand alone control of fans . You get to set on off Temps. Great solution to those old cars with this common problem.

I love this fan controller I’ve had it on for about 2 months and I love it! I ran it with my cantor fans on my 93 mustang and they click on as soon as it hits 106 (I did it low because I stuck the probe on the intake) I would recommend to buy the one that connect to the thermostat housing.

Works as described. Easy to wire up. Using it on a Mazdaspeed 6 where the fan control module likes to fail. The stock fan control doesn't turn on until 219 degrees, so being able to control the temperature is great for the warmer months.

I was expecting to get a new part, then the package came and when I opened it I couldn’t help but notice the dirt and rust on the part , not a very good start, I hopefully can get a new unused one 🤷ðŸ½â€â™‚ï¸
