How many channles on new model AUX? If there are 3 ( IAT EGT A/F) of them, then how to control them? There is only one AUXFX trimmer. Should be 3 too?

These is only one but can be used for anyone of named sensors. IAT is inverted.

Is this also true for the hfs4?

Would this be 0.5v = 0% flow and 4.5v = 100% flow?
And I think more importantly can units for flow be better calculated by a procedure similar to finding the max flow during set up. Something like:
-remove jet from intake.
-Set unit to test. Collect fluid for set time (10, 30, or 60 seconds).
-Measure amount of liquid and log voltage on pun 6.
-create new voltage vs flow map .becomes .5v = '0 units of measured liquid per duration of test' (ex. 0cc/minute) and the voltage measured during the test is now equal to 'amount of liquid'/'duration of test time' (ex. 500cc/minute)

Does that seem sane? Or is the max flow at 4.5v in an amount/time unit already known?

Thanks!

I think RICHARDL has mentioned very useful points that you can get benefit of it

Hi,

Wich pin should I use to log when WI is triggered??

Regards.

#30 .......... system status (signal level). 0v =off 3V=standby 8V=triggered.

I can only log 0-5v source. Any alternative? I just want to log when WI starts.

Regards.

When you can log 0-5V, 8V will be read as 5V (clipping by your logger)

Your log will look as:
0, 3V and 5V.

I don't quite see the point of data logging the status of the aquamist, the data is pretty static, once triggered. It woild be more useful to log the water flow (via the yellow wire of the user port). It is a 0-5 signal.
