I have for sale a used Auber Instruments PID Temperature Control Retrofit KIT for Gaggia (model KIT-GG). It is from Auber Instruments in the US and is designed and programmed for Gaggia Classic and Coffee series machines. I bought it in July 2007 and installed it on my Gaggia Coffee Deluxe.
I bought it to improve the temperature stability of the boiler in my Gaggia Coffee Deluxe and to get a better tasting espresso shot. I found the boiler had too much temp fluctuation without it. I was tired of having a sour and cold shot one time and a hot and bitter shot the next.
Installing the PID was straightforward. It made a big difference to the boiler temp stability and also shot temp. It also significantly improved the taste of the espresso. You can easily set the brew water temp to suit your taste and bean variety.
The PID can also be used to monitor the boiler temp when you are steaming. This takes the guess work out of knowing when to start frothing milk to keep the heat element going while youre steaming.
Im selling the PID as I upgraded my espresso machine and no longer need the PID or the espresso machine.
PLEASE NOTE THAT ONLY THE PID KIT IS FOR SALE. This includes:
- the PID itself
- all wires
- the RTD temp sensor that screws into the wall of the boiler in place of the original brew temp thermostat
- the SSR
- the installation instructions and user manual
Obviously, the PID kit will be partially assembled as it has been installed and used.
Installing it is straight forward as long as you have some knowledge of electronics wiring and safety - the instructions are very good. YOU DO NEED TO EXERCISE EXTREME CAUTION INSTALLING IT AS THERE IS 240V UNDER THE HOOD OF YOUR ESPRESSO MACHINE.
It’s for sale at $150 (plus postage). I paid $190 for it so this is a considerable saving. It is still in as new condition. My preference is for Melbourne pickup. I will ship in OZ as long as youre prepared to pay for postage.
Please PM/email me for more details.
Cheers
