Service manual April 2017 Uber boiler
3.1 SERVICE SETUP (software ver 1.10)
The following information is for Calibration purposes and should not be required for normal
use conditions.
To enter calibration mode press all four buttons on the front tile at the same time and hold
them until SERVICE SETUP message will appear on the first line of the screen (approx. 5
seconds).
Buttons on the left hand side change calibration option (up/down): See options below
Buttons on right hand side adjust the calibrated value (up/down, press longer to repeat).

Options 1 – 10
Description
Default
value
Sets offset value for tank temperature sensor.
The offset is the difference between absolute
temperature and a measured one.
It is factory set using calibrated instruments.
TEMP shows live readout from tank sensor with the
applied offset.
0.0
Sets offset value for font temperature sensor.
The offset is the difference between absolute
temperature and a measured one.
It is factory set using calibrated instruments.
TEMP shows live readout from font sensor with the
applied offset.
0.0
Sets maximum temperature at which the element
can be switched on. Both sensors (tank and font)
are monitored, if any reading is above set value, the
element switches off.
97.5
Sets heating delta factor. This number tells the
software how many energized seconds it will take to
heat up the tank by one degree. This number is
proportional to the size of the tank and inversely
proportional to the power of the element. Setting
value too high will make the machine overshoot too
much; setting too low will make the process of
reaching the set temperature slower. This value
must be altered for different tank sizes and different
voltages (see next page for info & table)
(8.0
for 2L)
(13.0
for 6L)
@230V
Sets the time for which the inlet opens every time
the machine needs water. It minimises temperature
fluctuations. The value should be picked to allow
0.5°C cooling after water intake and depends on the
tank size and element power. This is a factory
setting and should only be changed by trained
personnel.
