15
EDIT RECIPES
selection buttons will be displayed. You can
either change this configuration by clicking
each button individually and chose recipes
from the list which will be explained later. Or
you can choose a whole set of recipes that
you can put together (check page No. 16)
Please remark that your adaptions are
made directly on the device. There is no
need for a transfer command or a click on a
confirmation checkbox here.
4.4.1 PROVEN MODE
The proven tab provides a tool for a quick
and successful recipe creation. There are
four pre-set options for coffee and three
for tea, which will result in different flavour
intensities of the beverage.
For the coffee recipes, the brewing
temperature and the pulsation of the water
flow is pre-defined, based on the experience
of TONE coffee experts. You can simply
adjust the amount of water (Insert the
desired value using the keyboard or the
arrow keys.) and choose between cone and
flat filters. Make sure you have installed the
correct shower screen insert for each filter
type. For the cones you need to install the
screen with 5 holes, for the flat filter the
screen with 18 holes.
Enter the desired recipe name and click the
save button. Your recipe will appear on the
recipe list.
If you do not enter a specific name, the
program will give you a name for the recipe,
which includes the strength of the coffee,
the amount of water, and the type of filter
used.
The settings of the tea recipes are slightly
different. Choose the water temperature
considering the type of tea which shall be
prepared. The different tea options differ
regarding the number of pulses and their
characteristics.
The name of a tea recipe will tell you the
strength of the flavour, the amount of water
and the brewing temperature.
If a recipe is no longer needed, you can

16
delete it in this window by clicking on the
trash bin and selecting the recipe(s) you no
longer need.
4.4.2 CREATING SETS
You can compose a set of recipes by clicking
on each button of the four square buttons
and choosing a recipe from the list.
Once you have made your selection
of recipes, press “save set”, choose a
meaningful name and select the desired
category. Press then save again.
Then press “select set” and select the
desired set in the corresponding category.
If you press “edit set” you can change one
specific set or delete it if no more needed.
4.4.3 ADVANCED
The Advanced tab provides you a very
intuitive and comprehensive tool for the
creation of new recipes. You can set the
temperature of each extraction phase
(bloom, turbulence, development) and
define the characteristics of the water pulses
(quantity, flow ratio, duration, interval).
First of all, you should set the water target
which you would like to produce. This
value will not be exceeded. Varying the
bloom or the turbulence phase will adapt
the development phase automatically. The
development phase itself is self-adjusting
between duration and flow ratio of its pulses.
Second, you can define how much coffee
you need for your recipe by specifying the
brew ratio. The amount of coffee is indicated
in small letters below. In the same place, you
will also see a recommendation of how much
water is needed for the blooming phase (this
can be transferred to the blooming column
if required).
EDIT RECIPES

17
ADVANCE
When you have finished your recipe, you
can save it by giving the recipe the name
you want, selecting the right category and
clicking “save recipe”. It will then appear in
the selection lists when you press the desired
key on your selected machine (Touch03)
and select it from the advanced chapter.
There is also the possibility to change
existing advanced recipes by clicking “edit
recipe”.
A new category can be done by pressing
the + button in the advanced recipe list.
4.4.4 FREESTYLE
The freestyle chapter provides a way to
create a recipe entirely without restrictions
or frameworks.
As a first step, you can define the number of
pulses (maximum 20) using the + and - keys.
Further you can define the parameters per
pulse individually. In the upper part you can
see the total amount of water and the total
time of the recipe.
After assigning a specific name and
selecting Coffee or Tea, you can save the
recipe with the „save recipe“ key. Again, it is
also possible to modify existing recipes with
the „edit recipe“ key.
4.5 IMPORT / EXPORT FUNCTION
If you want to use an existing recipe or
send a recipe you have created to someone,
you can use the import / export function.
Open the desired tab (proven, advanced or
freestyle). Press the edit recipe button. Now
you can decide whether you want to import
a new recipe or export an existing one.
Import
Select the button if you want to import a
new recipe (sent to you from somewhere
else) and retrieve the file from where you
saved it on your device.
Export
Select the button if you want to export a
created recipe. The button will turn blue (see
pic. 1) and you can now select all the recipes
you want to export. Once you have done
this, press the button again (the button will

18
now have a green checkmark, see pic. 2) and
select your desired memory location.
Pic 1 Pic 2
4.6 SERVICE
The Service tab provides possibilities to
customise the brewer identification and
the calibration. And you can also check
all important parameters. Clicking on the
service tab will automatically open a login
pop-up window. Entering the password
“TONEservice” enables all available options.
Select one of the brewers listed in the left
column.
In the field “Location information” you can
enter a meaningful description of your
brewer and its location.
In case your brewer should extract more or
less water than intended you can tweak the
flow rate by setting a value below 1 in case
you want to reduce the amount of water or
a value above 1 if you want to increase the
amount of water. This is a very sensitive tool
an can only be adjusted in permille steps.
For the exact calculation of the flow
correction you can use the calculator.
Enter the desired quantity (target) and the
previously measured quantity in the “result”
field. Then press the “calibrate” button to
transfer the calculated correction to the
“Flow” field. This correction is always added
to or subtracted from the existing correction.
In case your extraction temperature doesn’t
fit to the set values of the recipes (e.g.
when there is very cold water supply) you
can adjust the temperature by clicking “+”
or “-“. The maximum values are +5/-5°C.
Keep in mind that the maximum possible
temperature of a recipe is limited at 97°C.
Theoretically you could then achieve a
temperature of 102°C. The heating system
will then produce steam instead of water,
which needs to be prevented in order to
achieve good brewing results.
