Temp Probe Numbering

[bubbles]

Hi everyone, not sure if this is the correct forum so please feel free to move.

Can someone please explain the temp probe number scheme to me?

I started using my unit for the original probe that I placed in the sump (T1_PROBE). I've recently added a second longer cable probe to monitor my display temp. I would have though that the newly added probe would be T2_PROBE but after playing around a little tonight it released it's not. I did not change the plug of the original probe when adding the new probe.

Does this sound correct?

Thanks

Looking at the front of the unit, the rightmost port is T1, the middle is T2, and the leftmost is T3 (closest to the pH connector).

No. that is not the case... the probes have serial numbers from the factory. They will always be assigned based on that number. Has nothing to do with the ports they are plugged into. This is where the confusion is..

You will either have to move them around based on your desired location or you will need to change your code to match the probes.

Ok that makes sense then. The newer cable I bought must have a serial number such that it gets allocated as T1.

Is there any way to tell which port has which probe plugged into it? If I were to add a third probe it would be a little frustrating to try to figure out the new allocation yet again.

Best way that I figure out was to take them out of the water

I know, that's how discovered it in the first place

I just posted about this, and then with some searching I found this thread.

I have a 3' probe that I want in my sump, and a 10' probe that goes to my tank. I want to add another 3' probe to use as a room temp.

Also, which one would kick on the heaters in the sump?

Your code should have something like this:

Code: Select all

  ReefAngel.TempProbe=T1_PROBE;
  ReefAngel.OverheatProbe=T1_PROBE;

Change it to assign which port the controller uses for your heater.
