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
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.
Step 2: Open Your New RANCO Controller
lift up the paperboard cover that's inside the bottom and you'll see two terminal strips.
The upper terminal strip will be labeled 240 - 120 - COM. We will be wiring to 120 & COM.
The lower terminal strip will be labeled NC - NO - C. We will be wiring to NO & C.
Step 3: Mount the NM Connector
Step 4: Cut the Extension Cord Into 2 Pieces
Step 5: Strip Off Outer Covering
Enough covering has to be removed so that the uncovered wires reach from inside of the NM Cable connector to just past the top terminal strip.
Save the black wire you cut off! You will use it later.
Strip the ends of all three wires then twist the loose ends together to keep them tight.
Step 7: Insert the Black Wire From the Cord Into the Proper Terminal
Step 8: Check Jumper Length Then Strip Jumper Ends
If the wire is not long enough then you will need to cut a longer section from the remainder of your extension cord and pull out the black wire from the cut-off piece.
Strip the insulation off both ends of your jumper wire.
Step 9: Strip Covering & Insulation Off the End of Your Remaining Cord
Step 10: Wire the Upper Terminal Strip
Loosen the top terminal strip C screw, twist the two white wires together, insert the two wires in the C terminal and tighten.
Loosen the top terminal strip 120 screw, twist the two black wires together, insert the two wires in the 120 terminal and tighten.
Step 11: Connect the Ground Wires Together
You can see from the bottom picture that I have 2 white wires inserted into the top terminal strip C terminal and 2 black wires inserted into the top terminal strip 120 terminal.
