We finished up modifying our large chest freezer into a fermentation chamber. We decided to mount the Love controller in a project box instead of to the chest freezer as their is a good chance the freezer will die long before the Love controller does.
A XLR microphone connector was use to get Hot, Neutral, and Hot->Out lines to the controller. A mono 1/8" jack was used to get the temperature sensor into the controller. We used 4x 8lb magnets glued on the inside of the box to easily stick and move the controller. The XLR cable was sleeved in some Tech Flex to make it look nice. The magnets are great as we can stick the controller to the lid or the side etc, wherever is convenient. The wiring diagrams found on this forum were very strait forward and helpful in wiring this thing up. We may make more of these to make them interchangeable with various heating and cooling tasks around the brewery. Might go with a 4 pin XLR though next time just incase we need to do heating and cooling and need the extra wire.
