Sorry for the late reply

Answers to your questions:

1. As far as I know they are the same.
2. You can leave the fail safe out, no problems
3. You just use the default settings from the factory.

another qusetion please ,,
as i read in the book that the fast acting valve should be used in the engine area ,, in fact am afraid that heat in this area will effect sensor reading ?? so is there away to protect it from heat ??

How high is regarded as high temperature? There are cooler places in the engine bay, you will be a better persion to find it.

i installed everythings .. so i moved to next step , which is testing ..

i tested the system as the book , everythings were fine , gauge was fine , controller was fine , but when i want to active the pump it did not turn on .... why is that ??

Re: HFS-3 in porsche 997TT
 

How did you activate the pump? Make sure the 15A fuse in in place.

Like this:
- pump activation only: jumper SYS "in" with FAV "out".
- pump and FAV activation together: jumper SYS "in" with FAV "in".

can you take a close up picture of the under side of the circuit board for me please. Use macro mode if possible.

It appeared the wiring is perfect.
