This PID controller kit is designed to retrofit into the Gaggia Classic, Gaggia Coffee, and Gaggia Coffee Deluxe espresso machines. With a PID controller added to the heater control circuit, brew water temperature can be controlled to within ±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:
Basic 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).
The PID controller in this kit is specifically modified for home espresso brewing applications. Two additional parameters are included to balance the requirements of cold start speed, shot recovery speed and long term stability. This is a different controller from our universal controller SYL-1512.
The platinum RTD temperature sensor used is more accurate and has greater long-term stability than thermocouple sensors. Temperature variations within the controller’s 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
All the cables in the kit have higher temperature endurances than 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 caused by PVC insulated wires touching the boiler during operation.
Compared to 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.
90 days warranty and 30 days money back guarantee is offered.
The kit works for 115 VAC and 240VAC. The default PID parameter setting is for Fahrenheit units for orders shipped within US. Order shipped outside of US will be set for Celsius. Please specify if you want it changed.
Two different colors of the controller box are offered, the silver and black. The silver box is coated with clear anodized aluminum with a brush finished stainless steel front panel. It is suitable for Gaggia Classic or other machine with silver paint. The black box has a durable powder coating. It is suitable for other colored espresso machine. Please select the color of the box at the top of this page.
There are several versions of "Gaggia Classic" on the market. In US, the current model is 14101
, which has the traditional Gaggia aluminum boiler. European model RI8161/40
has the same design, and out kit fits 14101, RI8161/40 and RI9303
models. But in some of the European countries, the model is RI9403
, which has a stainless steel boiler with different thermostat mounting; our kits DO NOT fit this model currently. If you are still interested in installing our kit to a Gaggia model RI9403
, please contact us
. We are working on adapting our Gaggia kits to this model.
