INSTALLATION AND OPERATION MANUAL
-
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.
ANY MACHINE MODEL WITH A SINGLE BOILER MUST
NEVER
HAVE THE
"Pressure Switch"
OPTION SELECTED.
-
ON/OFF
: coffee boiler temperature controlled via temperature sensor with hysteresis (the oscillation
temperature interval for the boiler) of 0.5ºC, 1ºC or 2ºC.
IMPORTANT
ANY MACHINE MODEL WITH TWO BOILERS MUST
NEVER
HAVE THE "
ON/OFF
" OPTION
SELECTED.
ANY MACHINE MODEL WITH A SINGLE BOILER AND WITH PRESSURE SWITCH MUST
NEVER
HAVE THE
"ON/OFF"
OPTION SELECTED.
-
PID
: coffee 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 "
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.
WARNING
In order for the machine to work correctly, the values of the said constants should not be altered.
- If "
ON/OFF
" is selected, press the
MENU
button to confirm, and the display will show:
Temperature
ºC / ºF
With the UP/DOWN buttons, select the unit of measurement for temperature, in Celsius (ºC) or in Fahrenheit (ºF).
