I just finished a new fermentation chamber build with a 4.4 cu ft fridge. I added a 300W heater and use a Inkbird Temperature Controller ITC-1000 for control. I found I need a Difference Set Value of 1 degC to avoid short cycling (cooling cycle overshoots, causing a heating cycle, which also over shoots...repeat). Probably not much I can do to get tighter control, but am open to suggestions.
Thanks,
