Hey all,
I poked around a bit and could not find a clear answer. I have an analog Johnson Controls Thermostat. I have the fridge at max temp and the probe is taped to the fermentation bucket with bubble wrap over it to insulate. I am getting large swings in temp. The manual states there is a +/- 3.5 temp diff. However, setting the thermo at 68, I see a range of 72.2 - 61. I am using two thermometers to validate. One digital that is used for cooking. It has an external probe and I taped the probe to the fermentation bucket just like the thermostat config. The 2nd thermometer is your standard boiling type. Both are reading close to each others temps. It appears they are accurate to +/- 2 degrees of each other. So my question is do I have a faulty thermostat? Or should I set it at 68 and let the thermostat do its thing and ignore those thermometers?
