Step 5 : Active PID

Step 5 : Active PID
Active PID enables a much faster response to a espresso shot than just relying on the temperature. By monitoring your brew button your meCoffee will kick into high gear to provide a response as aggressive and stable as possible. A shot timer in meBarista is available to assist you with your shot duration.

Your meCoffee will need to be aware of the state of the brew button to make this happen.

Note: this is the installation manual for the legacy version of meCoffee shipped before July 1st, 2017.

meCoffee Active PID, connect brew button to terminal #5

Connect the black wire from the set to terminal #5 with it’s female side. Locate the brew button of your machine ( Silvia: upper left button ).

Remove the existing wire from the switched live terminal of the brew button ( upper right, orange ).

Connect this wire to female+male side of the black wire.

Now reconnect the combined wires to the switched live terminal.

Definition of success
Boiler lights up as soon as you press the brew button. The shot timer in meBarista appears.

If you are seeing a temperature overshoot of up to 10 degrees in your Silvia E, proceed to the next step.

Now would be the time to relax a bit and leave the machine to warm up for about 20 to 30 minutes. Are you ready for your first meCoffee’d shot?

From now on all steps are basically optional: if you do not really need the timer, preinfusion or pressure: skip these steps. Installation can be resumed at any time.
