I have decided to add a new chest freezer and A419ABG-3C Johnson Digital Temperature controller to allow our extra frig to be used for food and other non-homebrew beverages as in the past.
I am interested in how others might be setting their temperature controllers. My unit came factory set with a temperature differential of ‘5’ deg. and a temperature offset of ‘0’ deg.
If you have a minute please post up your settings along with any thoughts on the subject.
Offset is to adjust for drift as the probe ages or to add a little fudge factor. You can leave that at zero unless you know there is a difference. I have mine set to about .5 when I measure temp by attaching to the side of a fermenter. This gets me a more accurate number on the controller as compared to my reliable thermometers.
If measuring the beer (either in wort or attached to the side) I set the trigger to .5°. If measuring air temp inside the box I set the trigger to 3°.
Thanks for the replay!
