This PID controller kit can control the brew water temperature, steam temperature, and the brew pump. It has all the features as the other listing titled “PID temperature control kit for Rancilio Silvia”, with the addition of steam temperature control and an extraction timer that can be programmed with the pre-infusion function. This kit is compatible with ALL Silvia versions, including the latest V4, V5 (E or M), and V6 (E or M) models.

This kit has the pre-infusion function and the timer can be used as a shot-timer. The pre-infusion is achieved by pumping a small amount of water into the coffee, holding off the pump for a second to let the water soak in, and then starting pumping for 25 seconds. This prevents high-pressure water from contacting the dry coffee powder that can create a fast flow channel, ruining the brewing process. It will improve the consistency of the brewing even if the coffee wasn’t perfectly tamped. The countdown extraction timer contains three segments: pre-infusion pulse (Tp), soak (Td), and brew (Tb). Each segment can be set by the user with a 0.1 second 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. Users can also bypass the timer to use the switch on the machine for manual control of the brewing process. The countdown timer can also serve as a shot-timer by showing how much brew time remains.
