So I have an InkBird temp controller for a new chest freezer I picked up. I ran a test on it with the temp controller and the temp continues to drop long after the shut off. I have the probe in a bottle of water. As a test set temp, I set it at 38F with a diff of 1. It cuts off when its supposed to but the temp continued to drop to 31F. The reason I chose this InkBird is because it accepts both a cooling and heating device simultaneously and switches between the two to help maintain the temp. My concern is if I cannot stabilize the temps on just the cold side within a few degrees, the wort may get too cold to even begin the fermentation to produce any of its own heat. Suggestions, folks?
