Hey you Inkbird Temp controller users, I have a question. Did you have to calibrate it right out of the box? I'm just now getting around to setting up my Inkbird w/Finnex heater combo and the controller appears to be off by 5°. I've placed 2 different glass thermometers in the sump near the temp probe and they're at 77° and the Inkbird is showing 82°. I'm not worried since calibration seems pretty straight forward. I'm just curious if any of you fine people had to calibrate it right out of the box.
