I currently ferment in a wine fridge which has a built-in thermostat which can range from 39F - 64F. I'd like to be able to chill below 39F, so I'm attempting to use an external temperature controller to bypass the built-in thermostat. I've attached a photo below of the built-in thermostat. In order to bypass it, would it be as simple as disconnecting the larger blue and red wires near the middle of the picture and then connecting them together? I'm assuming the brown wire is a ground for the circuit board, the smaller black and red wires in the top left are for the LED lights, and the black and white wires in the bottom right are for the temperature probe.
