A lot of homebrewers convert a chest freezer or refrigerator into a kegerator and they plug the fridge or freezer into an external controller to manage temperature. And if you want to go digital there is not a controller better suited for the job than a RANCO ETC-111000-000 controller. RANCO uses a thermistor on the end of a 8' cable to sense temperature & this gives you enough room to mount the controller on the side of your kegerator or on the wall behind your kegerator.

But RANCO ETC-111000-000 controllers to not make good mash controllers! The reason they don't is because they are just smart thermostats and a thermostat is always catching up to its set temperature. For example, let's say for example that you were to set your RANCO ETC-111000-000 up as a mash controller and you set your mash temperature to 145F. If you start at a strike temperature of 135F the RANCO would stay on until the mash temperature at the thermistor read 145F then it would turn off & the mash would cool until the lower trip temperature of 142 is reached & it will turn on, starting the cycle all over again. This cycle would continue and your average mash temperature will be right in the middle - at 143.5F. The correct temperature controller for your mash is a PID controller. A PID controller works to maintain 145F, not catch up with 145F. A PID controller will slightly over-shoot 145F to maintain your set temperature at an average of 145F. And a smart, tuned PID controller can easily maintain your mash to within 1/2 degree F of your set temperature.

Step 1: Parts Needed

There are a lot of instructions on the net telling you to add a electrical box and outlet to the bottom of your controller. The box and outlet are not needed and only cost you extra money! All you need to wire your RANCO ETC-111000-000 controller are:

1 - RANCO ETC-111000-000 controller
1 - 3 wire extension cord - I chose a 15' extension cord from LOWES because I also wanted to use the cord as a extension cord. You can use a shorter or longer cord.
1 - NM Cable Connector (clamp)
1 - wire nut (not pictured)

Regardless of what cord you buy make sure that it's 3 wire and has both a plug end and a outlet end. You will need to use both ends in this project.
