Important: if you have Gaggia Classic EVO Pro (2023), please scroll down to see Note 6 before you place your order.
Update: This kit is compatible with the latest Gaggia Classic EVO Pro (released in 2023) and Gaggia Classic Pro (released in 2018/2019) models, including the regular version (RI9380, 120V, or 240V) and the European version (RI9480, 240V). Please see the compatible model list below (Note 1 on the bottom). For the European version of Gaggia Classic 2015 (RI9403, 240V) please check KIT-GGX-EU.
Product Update: A special Edition with a COUNT-UP timer is now available for KIT-GGP in white LED (demo video link).
This pre-infusion PID kit (KIT-GGP) has all the features of a basic PID kit, "PID temperature control kit for PID Retrofit KIT for Gaggia Classic & Home (KIT-GG)", with the addition of pre-infusion and steam temperature control.
This kit has the pre-infusion function. Pre-infusion is achieved by pumping a small amount of hot water into the coffee ground, holding off the pump for a second to let the water soak in, then starting pumping water for 25 seconds. This prevents the high-pressure water from contacting the dry coffee powder which can create a fast flow channel, ruining the brewing process. It will improve the consistency of the brewing even if you didn't tamp the coffee perfectly. The pre-infusion timer contains three segments: a pre-infusion pulse (Tp), a soak time (Td), and a brew time (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 again. This feature allows a user to operate the brew pump manually, with the timer as a reference. A user can also bypass the timer to use the coffee switch on the Gaggia machine to manually control the brewing process.
Use the pre-infusion timer as a shot timer. A user can disable the pre-infusion pulse (Tp) and the soak time (Td) and only use brew time (Tb) as a shot timer to pump a specific time. In a Special Edition controller (available in white and blue LED), the timer counts up from zero instead of counting down to zero. Please watch a short demo video to see the count-up timer in a white Special Edition controller.
The steam temperature control allows the boiler temperature to be held at a tighter range during frothing. The operation is the same as the unmodified Gaggia machine. No extra button is needed to press for frothing. When the steam switch is turned on, the on/off temperature of the heater is controlled to 1 degree (°F or °C) difference as compared with the original thermostat's >10°C (or 20°F) difference. With this tight temperature control, you do not have to surf the temperature for frothing because the heater will kick on much sooner than the original thermostat. The on/off temperature can be adjusted by the user. The installation is completely reversible if you ever want to sell the machine or send it to service.
