Negative CO2 readings???

[pHreshperspective]

Recently, my Autopilot has been displaying a negative number (14595) during their sleep cycle. I have researched it and cant figure out why?

Maybe check battery or replace it

There isnt a battery. I works fine all day. Its just a light out thing and it takes about 4 hours before it happenes

Might be a calibration indicator. When was the last time you did a calibration?

Yesterday, and whats really wierd is that it shows "0" as the low and the -14595 as the hi

Weird. Idk man... do you have to take it outside for a while to calibrate it? I remember my sentinel manual saying something about that to adjust to ambient air c02 but I don't remember the specifics.

That's the right thing. A lot of these CO2 sensors need to be taken outside for a few hours once a week or something. Check the manual for your autopilot.
