Temperature controller: a little gadget that acts as an external thermostat. You set the temperature you want, plug the fridge/freezer into the gadget instead of the wall, and the gadget turns the appliance on/off to maintain the set temp.
Some brewers get similar effect with swamp coolers and ice packs.
Fermentation temperature control should be an early addition to your brewery.
