Fan controller
Fan controller
I'm looking for a way to controll a auxilliary fan from a W202 or W210. I found this: http://www.ma-uav.com/FanController.html which does exactelly what I want it to do - temp.sensitive controll of the fan speed.
[edit] all fine. They'r releasing a new version right now. I'll wait for it and buy that.

This is a Kenlowe version and the seller will ship to Europe.

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?

Actually I just looked up a rough costing and you should save good money as well plus be able to do other things with the board.
An Arduino, temp sender and a big Transistor would work out pretty good on this and is fairly simple to do. You probably wouldn't save much money on the deal but you could say you built it yourself.

The w210 fan controller is PWM controlled, and as i have a Arduino i thought i would give it a go and see if i can make it atleast run.
I figured out very quickly:
----- +5v at PWM pin gives you SOFT START but full fan power.
----- 0v at PWM pin (dont let it float, as it randomly comes on) gives you stopped fan.
I tried 1khz as suggested elsewhere, and using the 0-255 scale that arduino supports from the start, i found it didnt run until 50 or more. but then it gives oyu perfect control of speed. Will follow this up with my final code using a temp sensor to control fan speeds. could easily be used if you wanted Aircon too. Arduino copies re 3 UK pounds on ebay.
Well Chuffed. No other components, all i used was a resistor to protect arduino.

W639 Vito OM606 + 722.6 STD - in progress
Current progress: engine in, gearbox in, bumper bar modified to accept w210 radiator, audi electric fan, very tight squeeze, interior stripped out ready for new seats (w211) and custom dash with w211 clocks controlled by arduino with split fuel gauge covering main tank and auxiliary for Veg Oil ...
- DSL1 ECU for Electronic OM606 Pump (currently fitting wiring)
Next; 722.6 Controller, HX40 with homemade manifold, Air-to-water intercooler, homemade exhaust, MOT.... One day!
Just to follow up on this, i too was looking for a way of controlling an electric fan on my project, as no room for viscous.

This is probably a bit more expensive of an option but you get the other benifits of the logger with it. The tcm-2000 just has a 2d output which is just fine for just temp. But it also only has so many outputs.

12-12-2015, 10:07 AM #8I use my PCS datalogger and have used the TCM-2000 to run the pwm signal to the factory fan controllers as well. I run one for my fan and another for my water pump. The reason I like the D200 logger is that it has a 3d map for output and I can set not only based on temp but load or rpm for the water pump and vehicle speed for the fan on top of temp.

I just installed one of these, true PWM. No complaints at all. Pretty reasonably priced I think.

I built a controller for a Temic brushless fan out of a BMW a few years ago, I believe they are identical to what's found on some V8 Mercedes. Properly big fans that draw over 100 amps if you run them at full speed. I used an Attiny microcontroller to produce the 10Hz PWM signal needed to control the fan. I found that the fan only accepted PWM at 10Hz using my function generator. Any other frequency and it'd just run at full speed.
