ACP3 stuck on Celcius... don't know how to fix.

[jmkarcz]

If the probe was going, I would see different results, however, the probe is still in it's half life state and the conversion works out about right with the degree off set for the probe temp calibration.... It will allow me to flip over to Celcius and then modify my temp in the program, however, I do not wish to re-learn my reef parameters in celcius.

Has anyone seen this? Can anyone offer a suggestion?

Tried a hard reboot and reload... no Affect.

I have changed temp probes in the past, this is not a temp probe issue. At least not one I have encountered...

Thanks for any help.

Go into the setup menu on your controller, go to temp setup and make sure it's set to display in F, not C. Sounds to me like a setting got changed.

Another question - does the temp display correctly on the AC3, and not in Aquanotes, or is it wrong on the unit as well? If it's wrong on both - the above would be likely what you want. But, if the unit itself shows in F, then the setting is wrong in Aquanotes NOT the controller.

Sorry for the long wait in my reply, I have Final Exams right now, Ben a bit exhausted to deal with this.

Nope, it's on F. I switched everything to C a few days ago and it works... but I switched it back because it is to difficult to think of everything in terms of celcius after 17 years in the hobby,

The unit reads the same as the display, 24.6 degrees... which is offset and pretty close to actual temp of 24.6 degrees Celsius = 76.28 degrees Fahrenheit (thanks google). which is exactly what the thermometer reads.

It's discouraging... and I have unplugged and replugged... any ideas?

Have you tried going in to the set-up menu on the AC3 itself - NOT through aquanotes? If not, I would check there and see what you find.

Will try tonight. Thanks!

Ok, this is going to be alot of fun...

From the unit, if you switch from F to C, the controller now reads -03.94 degrees. I left it this way for some time and returned and switched it back to F. It returned to 24.6 degrees which in what I thought was C but off by about the offset amount that my probe is offset by.

If it were probe failure, my understanding is that it would be erratic or inconsistent or both. It is Consistently reporting the temp but is offset truly by 50 degrees (from the top of my head I'm not running back down to take an actual reading) because I run at or about 76 degrees.

So... um... any ideas?

Did you reboot the controller after changing the setting?

[ciphros]

Another thought, do you have a temperature offset showing on the control panel under temp setup (again, on the brain, not Aquanotes - I see you have a -0.52 degree offset in the box for Aquanotes)? It almost looks to me like you have ofset your temperature and it really is giving you F when you are reading 24.6 and it's giving you about -4C. If you do the conversion 24.6F is -4.11C, and -3.94C is actually 24.9F (*may be a result of the slope you have showing, since it isn't 1.0 - it'll be off by a small amount that I don't want to take the time to calculate unless it becomes necessary). So...to me it appears you ARE reading in F, but you have a huge temperature offset in the controller that is making things read funky.
