Pid Controller; Setting Temperature - Izzo Alex Duetto 3.0 Owner's Manual

PID Controller

The PID controller‟s display will cycle back and forth
to show the current temperature of each boiler.
The position of the decimal point indicates which
boiler the temperature is being shown for. The
picture to the right shows which boiler is represented
by which decimal point.

Setting Temperature

With the machine turned on press and hold both arrow keys until the display reads
release the keys. T1
temperature setting. While the temperature is still being displayed press either arrow key to
change the temperature.
After a few seconds the display will revert back to T1, then press the down arrow key to display
T2 which is your steam boiler temperature. Press the up arrow key to see the current
temperature setting. While the temperature is still being displayed press either arrow key to
change the temperature.
After the display reverts back to
temperature settings and go back to normal operation.
Coffee Boiler Temperature
The recommended brew range is between 195°- 205°F or 90°- 96°C. This can be easily
changed to match the coffee blend you are using and to bring out the different flavor
characteristics in the coffee.
A hotter temperature will bring out more of the bittersweet chocolate flavors and going colder
will bring out more of the fruity flavors. Going too hot may cause the shot to taste bitter and
going too cold it may taste sour. Experiment with different temperatures until you find the one
you like best.
Steam Boiler Temperature
temperature has been set to 255°F by default,
but can be easily changed. The table to the right
shows what temperature settings corresponds
to bar pressure. There may be a slight variance
in pressure depending on elevation since water
boils at different temperatures at different elevations.
Note: The PID display will turn off whenever the reservoir is empty or if the pump comes on to
re-fill the steam boiler which is normal and no cause for concern.
