So I have a chest freezer that I am using as a fermentation chamber. I have that plus a ceramic heater with a built in fan plugged into a Keg King MkII controller. Also inside the chest freezer is a computer fan that is constantly on to circulate the air inside of the freezer. I have a Speidel fermenter that I installed a thermowell to measure the temp of the wort while fermenting. I have noticed that when I set my target temp (66 degrees F) it is constantly overshooting that temp which in turn will cause a constant swing in the wort temps. When it goes over the 66 degree set point and the freezer kicks on, by the time it reaches that target temp it will continue to drop to around 65 degrees. Meanwhile the heater will then kick on to warm it back up to the target temp, and by the time that is reached it will overshoot it once again causing the freezer to kick back on. It is a never ending cycle throughout the entire fermentation. Does this seem to be the norm for this type of setup or is the constant cycling of temps causing unwanted stress on the yeast or creating unwanted off flavors? Is there something I could be doing differently to not cause the never ending cycle of heating and cooling of the wort? As a side note I have changed the temperature hysteresis on the controller from the default 1 degree, down to .5 degrees. It can go all the way down to .1 degrees, but I am worried at that point the freezer will cycle so often that I will burn up the compressor on the freezer a lot sooner that I would like to. Any tips or words of wisdom? Thanks!
