Once this procedure is completed, press the MENU button to move on to the following option:
ProbeSensitivity
LOW/MID/HIGH
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:
Service Cycles

temperature interval for the boiler) of 0.5ºC, 1ºC or 2ºC.
- PID: co ee boiler temperature controlled via temperature sensor, with variations in an algorithm of
three constants Kp, Ki and Kd. (RECOMMENDED BY THE MANUFACTURER)

OPTIONS ‘On/O ’ 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.
WARNING: In order for the machine to work correctly, the values of the said constants should not be altered.
