AUTO COOL CONTOLS RADIATOR OUTFLOW TEMPERATURE - YOUR THERMOSTAT CONTROLS ENGINE TEMPERTURE~
THE HF CONTROLLERS WILL POWER BRUSH OR BRUSHLESS FANS. AVOID USING A LOW FREQUENCY CONTROLLER ON A BRUSHLESS FAN = IT WILL VIBRATE AT LOW RPM,
THE HF COTROLLERS HAVE SOFT START, AC FAN SPEED CONTROL, AND A COOL DOWN TIMER. RADIATOR OUTFLOW TEMP IS CONTRLLED WITH FAN RPM. ALL OUR SENSOR WILL WORK WITH ANY OF OUR CONTROLLERS, NO YOUR ECU! HF CONTROLLERS RUN AT 7000 CYCLES PER SECONDS.
I just wanted to let you know that the HF-125 I ordered from you this summer has been absolutely great. As I said, I haul a lot, and big trailers, with my Powerstroke, and now that I'm running your controller, I'm finally getting the benefits of converting it to electric fans. All these years hauling trailers and I've been religious watching temps - I still am, but I can tell you it doesn't matter now if it is 40*f or 100*f, loaded, unloaded, headwind, no wind, 50mph or 80mph, the temperatures are stable all the time. I could not be happier with your controller. In fact, I'm so happy I just ordered a second one for one of my other trucks that I'm converting to electric fans now that I have found the proper way to control them.
Thank you so much for making a quality product.

Here are some handy tools for installing the Auto Cool Controller.
"Keep it Cool with Auto Cool."
LASER TEMPERATURE GUN
Use a laser temperature gun to measure your radiator and engine temperature. Point the spot on a black surface to have better accuracy. A bright or white surface will not read the correct tempature.
You can find these at Harbor Freight Tools and Home Depot.
DC VOLT METER
Use a DC volt meter to measure battery voltage. If you have an alternator not charging your battery, this simple meter could save you time to find the problem. Test your battery voltage with the engine running. It should be around 13.8 volts DC. If you find it at or below 12 volts with the motor running, the system is not charging. You could also have a wiring problem.
You can find these at low cost meters at Harbor Freight Tools.
DC CURRENT CLAMP METER
A DC current clamp is very handy to measure the current of fan motors. With Auto Cool Controllers, measure the full RPM current at 12 - 14 volts DC.
They can be found on Ebay. However be very sure that the current clamp you purchase will measure DC CURRENT!!!
