PID-parameter settings
The controller may be locked such that you can only change the operating temperature
(Sp, set at 93.0 °C) and/or a few other parameter values.
Unlocking the controller is done by pressing P and ˅ simultaneously for about 5
seconds. The display will read “COdE” alternating with the value “001” or “011”. With the
˅ key you change the value into “000”, the controller is now unlocked, press P to
confirm and return to operating temperature.
Locking is done similarly, change the value for “COdE” back to “001” with the ˄ key.
To gain access to the parameter settings in the PID, press the P key shortly such that
the display reads “Sp” alternating with the set coffee boiler temperature value (originally:
“93.0”). Press the P key again but now hold for approximately 2 seconds until the
display reads “AL”, then release the P key. The display will now alternatingly show “AL”
and “1.0”.
Pressing the P key shortly will scroll you through the different parameters, pressing the
up and down arrow keys ( ˄ and ˅ resp.) will change the value of the parameter on
display at that time.
Pressing the P key will store the (newly) set value and simultaneously scroll to the next
parameter.
When parameter “Y .0” is shown in the display, you may enter a “deeper” level of the PID
by pressing and holding the P key until the display shows “C111”.
Leaving all buttons untouched for more than approximately 10 seconds will return the
PID to normal operation in which the set value of the boiler temperature is shown (not
alternating).
Table 1. Shows scrolling sequence of PID and factory value settings of the individual
parameters (in degrees Celsius). Highlighted are the parameters and values to change
when switching to degrees Fahrenheit: change value for “Sp” last.
