The display will show the timer option for 'PRE-BREW ON' for each coff ee selection (1 espresso, 1 coff ee, etc.).
Pressing the UP/DOWN buttons, the desired time in seconds (from 0.1 sec. to 5 sec. in jumps of 0.1 sec.) can be
selected. Press the MENU button to select the 'ON' times for the rest of the selections.
Once this procedure is completed, press the MENU button to move on to the following option:
The display will show the 'PRE-BREW' timer 'OFF' option for each coff ee selection (1 espresso, 1 coff ee, etc.).
Pressing the UP/DOWN buttons, the desired time in seconds (from 0.1 sec. to 5 sec. in jumps of 0.1 sec.) can be
selected. Press the MENU button to select the 'ON' times for the rest of the selections.
Once this procedure is completed, press the MENU button to move on to the following option:
The display will show the 'PROBE SENSITIVITY' option for the level of water in the boiler. Press the UP/DOWN
buttons to select low (150KΩ), medium (400KΩ) or high (1 MΩ) sensitivity.
Once this procedure is completed, press the MENU button to move on to the following option:
The display will show the 'SERVICE CYCLES' option when the machine reaches the number of cycles selected. It will
send a visual alarm on the display as notifi cation. Pressing the UP/DOWN keys selects the number of cycles.

The display will show the machine heating control system option.
Press the UP/DOWN buttons to select 'Pressure Switch', 'On/Off ' or 'PID' and confi rm by pressing OK.
- Pressure Switch: boiler temperature controlled via pressure switch.
IMPORTANT: ANY MACHINE MODEL WITH TWO BOILERS MUST NEVER HAVE THE
'Pressure Switch' OPTION SELECTED, AS THE MACHINE WORKS WITH A TEMPERATURE
SENSOR IN ORDER TO CONTROL THE COFFEE BOILER TEMPERATURE.
- On/Off : coff ee boiler temperature controlled via temperature sensor with hysteresis (the oscillation
temperature interval for the boiler) of 0.5ºC, 1ºC or 2ºC.
- PID: coff ee boiler temperature controlled via temperature sensor, with variations in an algorithm of
three constants Kp, Ki and Kd. (RECOMMENDED BY THE MANUFACTURER)
IMPORTANT: ANY MACHINE MODEL WITH A SINGLE BOILER MUST NEVER HAVE THE
OPTIONS 'On/Off ' or 'PID' SELECTED.
In this position the machine will control the temperature according to its working conditions, adapting itself at all
times to the internal and external contour conditions.
The values for these constants will depend on the power of the element, the size of the boiler and the degree of
heat dispersion in the boiler.
