PID Retrofit KIT for Rancilio Silvia w/ pre-infusion

This PID controller kit has all the features of our other listings titled "PID temperature control kit for Rancilio Silvia, Deluxe", with the addition of  steam temperature control and extraction timer that can be programmed with pre-infusion  function.

The pre-infusion is achieved by pumping a small amount of water into the coffee, holding off the pump for a second to let water soak in, then starting the 25 second pumping. This will prevent abrupt high pressure water on the dry coffee powder that can create some fast flow channel to ruin the brewing. It will improve the consistency of the brewing even if you didn't tamp the coffee perfectly. The extraction timer contains three segments: pre-infusion pulse (Tp), soak (Td), and brew (Tb). Each segment can be set by user with 0.1second resolution.  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 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 >10C (or 20F). 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.
This kit will take roughly 15-30 more minutes to install because of the extra steps required to access the steam switch. The installation is completely reversible if you ever want to sell the machine or send it for servicing.

This kit fits all Silvia models, including the 2009 V3. However, if you have a model made between 2000 and July 2006, we can supply the kit with a screw type RTD sensor for better performance. To obtain the screw type RTD sensor, please select the "Screw RTD" at the bottom of this page.

A blue colored LED display option is offered. It will give the machine an cool look. To order this option, please check the box at the bottom of this page.
