Model#: KIT-GG (red LED)

We ship Fahrenheit version to US customers, Celsius version to international customers. 
Update: This kit is compatible with Gaggia Classic Pro 2018/2019 models, including the US version (RI9380, 120V) and the European version (RI9480, 230V)! For older European version of Gaggia Classic 2015 (RI9403, 230V) please check KIT-GGX-EU. If you have a Gaggia Classic EVO Pro (2023), please send seller an ebay message after you place your order.

This PID controller kit is designed for retrofitting into the Gaggia Classic, Gaggia Coffee, and Gaggia Coffee Deluxe espresso machine.   By adding a PID controller to the heater control circuit, brewing water temperature can be controlled to ±1 F° accuracy. Thus, it will significantly improve the taste of your espresso. Users can also easily adjust the brew water temperature to suit their own tastes.

The kit includes:

·        Custom manufactured PID temperature controller with parameters set for the machine.

·        Bright anodized (or black for Gaggia Coffee) aluminum box with mounting slot pre-cut and wiring hole sealed with rubber grommet.

·        Solid state relay with mounting hardware and heat conductive paste.

·        Platinum RTD temperature sensor with tip made for the thermowell on the machine

·        High temperature resistant wires, color coded, cut to length and terminated with proper connectors

·        Instructional CD with text and photos.

 To install the kit, users will need the following:

·        Knowledge of electronics wiring and safety.

·        Screw driver, pliers, a socket wrench and small amount of alcohol.

·        30-60 minutes of time.

No requirement for special tools. No requirement to learn how to set up the PID controller (usually, this is the most challenging part of the project for espresso drinkers with little electronics background).

 Unique features.

1)      The PID controller in this kit is specifically modified for home espresso brewing applications. Two additional parameters are included to balance the requirement of cold start speed, shot recovery speed and long term stability. (this is a different controller than our universal controller SYL-1512)

2)      A platinum RTD temperature sensor is used which is more accurate and has greater long-term stability than thermocouple sensors.  Temperature variations within the controllers environment will not affect the accuracy of its reading.  In addition, the sensor is built inside of a screw and will fit into the existing thermowell for the coffee thermostat

3)      All the cables in the kit have high temperature endurance as the original cables used by the manufacture. We use color coded cables with either fluoropolymer or silicone insulation. This will prevent the potential electrical shock resulting from PVC insulated wires touching the boiler during operation.

Compared with buying the controller and components separately, this kit is a great value. It not only offers better performance but also saves you time and money. The kit includes 20 different types of parts that would cost substantially more if purchased separately (26 pieces total). In order to save customer’s time on assembling and reduce the chance of making mistake, we also pre-assembled these parts and set all parameters for the controller. The only work needed to be done by the customer, either has to be done during installation or is difficult to ship pre-assembled. This reduces the project time from days (or even weeks considering ordering these parts separately) to less than an hour.

6-month warranty and 30 days money back guarantee is offered.

The kit works for 120 VAC and 240VAC. The default PID parameter setting is for Fahrenheit units for order shipped within US. Order shipped outside of US will be set for Celsius. Please specify if you want it changed. The default color of the controller box is silver. Please specify if you want black box for Gaggia Coffee.

Note 1: Gaggia Espresso machine is not included in this listing.  

Note 2: For advanced features like pre-infusion timer (countdown shot timer) and steam temperature control, please see our advanced kit. Part number: KIT-GGP. 

Note 3: This kit fits the Gaggia Classic Pro (RI9380/46, released in early 2019), Gaggia Classic & Home (which has the traditional Gaggia aluminum boiler) including 14101, RI8161/40, and RI9303 models. But this kit doesn't fit new European model RI9403, which has a stainless steel boiler with different thermostat mounting. For RI9403, please check KIT-GG-EU (ebay item number: 201922568118).
