I’m after some advice on temperature control. My fermenter sits on a heat pad in a fridge which is controlled by a digital temperature controller thermostat. The fridge kicks in when the temperature is getting too hot and the heat pad kicks in when too cool. I have the thermostat sensor submerged inside the fermenter. Going by the recommended or ideal temperature of the yeast what should I set the fluctuation difference to on my thermostat? Should I set it so it’s bang on the recommended temperature without any fluctuation or is there room for a certain amount of fluctuation before the yeast starts producing unwanted flavors? If I have it set so there’s no fluctuation, I’m presuming there will be a lot of switching on and off between the heat pad and fridge which probably isn’t ideal for the life of the appliance.
