Temp probe issue, T1, T2, T3 moving around?!

[meadowsad]

So I had a weird issue tonight. My T1 probe jumped up to 185 degrees and put the system in overheat mode, the head unit was frozen so I had to unplug it. All was good for a few hours and it did the same thing again. I figured it was a faulty temp probe so I changed it with an extra I had. This is when things got weird... On my head unit T1 was always in the middle T2 was on the right and T3 was on the left. If I plug in one temp probe in to the center the head unit shows it as T1. If I plug in a temp probe in to what I think is T2 it then shows up as T1 and the original T1 is now T2. If I add a third temp probe it shuffles things around again.

I am not sure if this is by design or something with a new firmware since I haven't had to mess with the temp probes in a long time. Not sure what I should be doing next!

Yes, temperature probes are not position specific.
They get assigned a unique ID by the manufacturer and we the probes get listed according to that ID.

I guess my next question is how to I get them to report the way that I want. My probes are different lengths and I want to make sure I get a specific one on T1 regardless of what other probes are installed.

You can change which probe that controls the stuff instead of using only T1.

Ah ok, so just change it in the code and let the head unit assign whatever it wants? Makes sense if that's how it works.

In your code, there should be a line like this:

Code: Select all

    ReefAngel.TempProbe = T1_PROBE;

Simply change it to whatever probe you want to use to control the heater/chiller.
You can use T1_PROBE, T2_PROBE or T3_PROBE
