I want to use a fridge to control the temps in my carboys, but I'm curious how to control the temps without having to keep adjusting the thermostats.
As the yeast get active and start producing heat, the fridge temp needs to be turned down to keep the heat in check. But as fermentation progresses and the yeast slow down, the fridge will have to be turned back up to keep the temps from getting too cold.
What can be done to automate this adjustment?
If I stick a thermowell in the carboy and cycle the fridge based on the carboy temps, it seems the temps would swing quite a bit as there would be a lot of lag in the system.
Would using a two-stage heating/cooling system improve that lag? Running the fridge till target temp is reached and then running a heater in the fridge to prevent temps from coasting too far below the set value.
