If you don't know what it does, why do you want one? There's a very good wiki on what it does, but in short, it gives a much tighter control over fluctuations in boiler temperature, by cycling the heating element at more stringent parameters.
I would think you can add it to any machine that doesn't have it already...though I don't know your machine at all...and I may be wrong in assuming that.
. Always remember the most important thing is what ends up in your cup! Check me out on Instagram!
PID is the interface, SSR is the switch that connects directly to the heat element, Connect the PID to the SSR.
If you look at the back of the PID it's 2 terminals for PID power, temp sensor, SSR. It's a simple install but you need to rip apart your machine for this.. If you get it installed you will have one happening machine :D

No OP reply since opening the thread and that was last log on.. I have watched this thread unsure how to respond. I looked up the machines. The Barista Express BES 870 has “electronic PID temperature control for increased temperature stability” and the BES 860 has “digital technology” for accurate temperature control. This may be on an internal board as I do not see the controller or digital readout. Which machine is the OP asking about and how is the temperature controlled?
