I have a new Profilux system that I am just starting to integrate into my 350 mixed reef system. So far the only two dynamics that I have operating on/through the Profilux is a Profilux doser and the temp probe. The Profilux doser is working very well. The Profilux temp. probe is where I have some questions. My current system, less the new Profilux, has a different temp controller, I also utilize a floating thermometer in sump and the chiller registers temp. Those three components existing are +/- .02F from eachother. The Profilux is reading 1.3 or 1.4 F warmer than the existing components. Could it be that I am not properly setting up, calibrating or not handling the "extension" dynamics of programming the temp probe? I have run through the programming of the temp probe four times complete. I wait for the extension dynamic as requested and then it requests "return" and we move forward to calibrate ...........
The variance is problematic because at the "heat" of a given day, the Profilux will be wanting to chill the water or turn on fans while currently this reef system is not requiring that action.

Thank you in advance for your ideas and solutions for me.
