03/03/2017 Note: The latest SSR units have swapped pin 6 and pin 8 to positive pins (old SSR units have pin 6 and pin 8 as negative pins). When installing your kit, make sure to connect the red cables from the controller to the positive (+) pins, and connect the white or blue cables to the negative (-) pins. This step supersedes Fig. 17 in the user manual. Text in section C.1 of the manual still applies.

This PID controller kit is built with perfecting a single-boiler machine in mind. With the addition of steam temperature control and an extraction timer that can be programmed with pre-infusion, this PID can turn your Rancilio Silvia into a professionally consistent machine. The pre-infusion functionality injects water directly into the espresso grinds to saturate the coffee before actual extraction, ensuring far less variance when the pump flings into full motion.

The steam temperature control allows the boiler temperature to be held between a tighter range during frothing. User operation is the same as regular machine, so there isn't a lot of extra fiddling to figure this PID out. The added consistency is a welcome change, as the most common complaint we hear from Silvia owners is a lack of this consistency.

This kit fits all Silvia models, including the model made after 2009. However, if you have a model V1 or V2 made between 2000 and July 2006, the PID with screw sensor offers better performance.

Please be aware that installing this on your Silvia will void any existing warranties.

How the PID Retrofit Kit Works

Pre-infusion is achieved by pumping a small amount of water into the coffee grinds, then activating the pump for extraction following a few second delay. This will prevent abrupt high pressure on the coffee grinds that can create inconsistency. Overall, this unit takes quite a bit of the guesswork out of the process.

  • The extraction timer contains three segments: pre-infusion, soak, and brew. Each segment can be set with only .1 second variation.
  • When the ">" key is pressed, the controller starts the brewing sequence automatically.
  • The pump can be stopped at any time by pressing the ">" key a second time. This feature allows you to operate the brew pump manually, with the timer as a reference. User can also bypass the timer to use switch on the machine for manual controlling the brewing process.
  • The steam temperature control allows the boiler temperature to be held at tighter range during frothing.
  • User operation is the same as the regular machine; no extra buttons are needed for frothing. When the steam switch is turned on, the on/off temperature of the heater is controlled with 1 degree (F or C), as compared with original thermostat's >10°C (or 20°F).
  • With this level of temperature control, you will no longer need to surf the temperature for frothing, because the heater will kick on much sooner than the original thermostat. The on/off temperature can also be adjusted by the user.

Does your shop offer the Rancilio Silvia AND (PID Retrofit Kit for Rancilio Silvia with Temp control, Pre-Infusion and brew timing installed? If so I would think it would be slightly more that the Rancilio Silvia with the standard PID combo you currently offer on the website. So with that in mind, if you do offer the better PID and Silvia installed, with is the price?

Best Answer: The Silvia with PID installed utilizes this PID with Pre-infusion, so you are able to adjust pre infusion, shot timing and temperature.

Is there a "manual" mode for the PID where I can still use it to regulate the temperature, but brew manually (i.e. without the pre-infusion, delay, and timed extraction)? Just purchased the kit from SCG and having it locally installed. Excited to give it a whirl.
Christopher L on Mar 28, 2016
Best Answer: I contacted the manufacturer of the PID and provided proof of purchase. Then they emailed the manual with the instructions for programming the PID. It was pretty straight forward to set the times for the different parts of the brew cycle.

Once the PID is installed, how does the the steaming process work? Do I just turn on the steaming function as usual and wait for it to come up to temp (using PID as the indicator) or is there something else I have to do?
Christopher L on Mar 28, 2016
Best Answer: Christopher,
The way I use my PID, is to prepare portafilter with tamped coffee, run a shot of water into my cup to heat cup, turn off brew switch and turn on steam switch. The steam temperature will come up very fast. When it gets to about 268 degrees, bleed off water and start steaming. The temperature will continue to rise in the boiler to create plenty of steam. If you wait until it reaches max temperature then you will be steaming as the temperature is decreasing, which I don't recommend. Make sure to run water out of nozzle to refill boiler and you are now ready to pull shots. I love the PID on my Rancillio Silvia.

I have the pid installed on My Silvia and have thought about the pre-infusion.. Since I primary doing single shots with about 12g for each shot, what pre-infusion time is recomended? And what soak time?
I beleive default setting is for a double shot. Concider it was a bit too long..

Ollie on Jan 29, 2015
Best Answer: Yes, I think the default is for a double shot. The answer to your question depends a lot on how it tastes better for you, so you need to spend some time setting up to your taste and your other settings. The idea is to have some pressure initially and the coffee should not drip at all. The soak time doesn't need to be long: perhaps the default is good for 12g.

I have a Rancilio Silvia v3 (not purchased at SCG). If I send it to you, can you retrofit the Auber PID to it? Cost? If no, do you know of anyone in the Philadelphia area who can perform this service?
Brian A on Aug 16, 2014
Best Answer: Yes, we can install a PID on your Silvia, however the fee is the cost of the PID (currently $235), plus a $100 install fee, plus the shipping both ways. This can quickly add up to about half or more of your machine cost, unfortunately! There may be someone local to you that can work on Rancilio and would possibly install a PID for you, or you may feel comfortable doing the install yourself. We have instructions for installing the V3 Preinfusion PID under the Resources tab on the PID page, so I might check this out first. Otherwise we can install it here if you submit a repair request, but we do not have lists of other service centers across the US. Hope this info helps!

Can the PID for the Rancilio Silvia be installed by me or is it mandatory that it be done by a service person?
Don H on May 5, 2016
Best Answer: Don,

I installed my PID with a little help from wife. While I connected the wires to the appropriate connections my wife verified each step. I read the instructions two to three times before I started. I have a background hobby of assembling and wiring electronics, so I felt comfortable. It took me about 3 hours to complete.
If I knew the time was so long to complete the task I may have found someone to assemble it for me, however the persons I would have asked were busy at the time. I can tell you it is worth the time and money for the PID, I have had very good and consistent expresso and cappuccino.

Take your time and you will be fine.

Reviewer under "Review" here warns to avoid pre-infusion function because it also activates solenoid valve (during pause). Would appreciate your opinion/ experience on this?
A shopper on Jun 22, 2015
Best Answer: When the solenoid activates it doesn't suck water out. The water in the portafilter is under pressure and the solenoid gives it another path to escape to, so there might be some water that leaks out, but I doubt theres enough pressure built up for all the water too come rushing out!!! Also, crema is not being produced during the pre-infusion so there's no way for crema to end up in the drip tray.

Am I able to mount this kit on the side of the silvia or does it have to go near the GH?
A shopper on Mar 2, 2016
Best Answer: Yes you can, but why? It fits perfectly, and elegantly, between the wand and group head. The temperature readings are from sensors that are inside the machine so the group head's temperature does not effect the readings nor the operation of the PID. I mounted mine with little clearance but not touching the group head. It works great! Follow the enclosed instructions, step by step, and it is easy to install. Once you adjust your grind for the perfect shot, you will not only love the espresso, but also the convenience of pushing a single button for a perfect shot every time.

Is there a list available of the factory settings (times and temps) that the PID is set for?
Ben S on Aug 7, 2017
Best Answer: I installed the PID a year ago and can’t recall the factory settings. My current settings are; pre-infusion at 2.5 sec, temperature at 218 F and shot duration at 25 sec. That combination seems to work very well with the black cat analog beans I use.

Best Answer: No, unfortunately this is designed for 110V models. As the wiring requirements will be different, you'll want to choose a PID kit that will work with this higher voltage. We do not carry a PID that will work with 220V since we don't carry machines that it would work with, sorry!

PID for SilviaReview by BMH
Echo all above, it really is a must for Silvia, takes all guess work out now, and have improved consistency and quality of espresso (Posted on 3/21/2017)
Easy to install. Fun to use. Saves time.Review by Garret
Purchased and installed on my three year old Silvia. Install was simple, especially with the great SCG video (I also followed the PDF). Big thanks to SCG staff for their quick response to a question I had. Since the install, the consistency of my shots has increased greatly, and I'm finding that I waste a lot less water "temp surfing" every morning, which is a nice benefit. My only gripe would be that the controller could look a bit sleeker, and have a better UI/button arrangement...looks a bit Star Trek for my liking. It's also pretty expensive, but for me it's worth it as I was getting frustrated with the ritualistic approach to temp surfing...the time I save with the PID is tremendous. (Posted on 9/23/2016)
Well worth itReview by T Brady
The PID works well and has improved my shots. I was mostly happy with surfing, but the PID has taken them up in quality - not dramatically but certainly noticeably. No special skills are required to install and the installation time was about 45 minutes or so (make sure you use the correct instructions and operational manual, on the SCG website). Whether you like pre-infusion or not, the parameters are easy to change and there is a SCG video on the topic. One added benefit is that the timing of your shot can be controlled such that the pump shuts off after 1oz or whatever it is that you prefer to pull. The device is attractive. Overall, I would recommend this kit. (Posted on 1/26/2015)
A must-have if you're already spending $$$ with the SilviaReview by A. Da Costa
After spending almost $700 on a Silvia, you don't want to be temperature-surfing and playing tricks with the machine to get consistent shots. Just get a PID and focus on other things that matter to get a good shot.

A couple of negatives about the PID though:
1- It comes with instructions on how to change it to Celsius, which I did. The problem is that the temperature thresholds (brew and steam set points) do not convert units automatically. This is a great design flaw in my opinion. You could actually burn your heating element if you don't notice it right away. The default set point for brew is 221, which is fine for Fahrenheit, but once you change the units to Celsius, it'll try and heat your boiler to 221 C, which is 430 F!!! You also need to change the steam temperatures (two settings, on/off). The instructions don't mention anything about this.

2- It comes with the option to set a pre-infusion time. Do not use pre-infusion or it'll produce a worse shot. I checked out the electrical diagram on Auber's website and now I understand what the problem is. The way the relay used to control the pump is hooked up is such that the 3-way solenoid valve is also switched to absorb over-pressure from the brew head once the pump stops. In other words, after a few seconds of pre-infusion, the pump will stop for the delay before the full shot and all the delicious crema that's starting to form in your portafilter will be sucked out to your drip tray!!! Design flaw! They should have used a separate relay for the solenoid valve so that it only sucks the moisture out of your portafilter when you finish pulling the shot, and not during your wait-time after the pre-infusion. (Posted on 11/16/2014)
