In the past few years a few double boilers machines have come to market. Yet people continued to ask when will a dual boiler, TOTALLY PID controlled machine, with an E61 group be introduced? Well that time has come say hello to the NEW Alex Duetto II by Izzo. So what is different about the NEW Duetto II? All functions are now controlled by the PID.
The following is a list of functions controlled by the PID:
Easily changes the machines operational mode from 15 amps to 20 amps.
Temperature display easily changed from Fahrenheit to Celsius.
Can program the offset settings for both boilers.
Default values for P, I, and D can be changed (please consult with our Service Department prior to changing).
Either boiler can be turned off. (save energy and turn the steam boiler off if you only want espresso)
Note: You can also turn the steam boiler on and off with a switch on the side of the machine.
