5.7 Setting the Heating
Switch the heating on only after you have filled the heat exchanger with water!
Thermostat for minimum operating temperature and heating:
The thermostat for minimum operating temperature prevents too cold milk or water from
being distributed. When the temperature in the boiler falls below the set minimum tempera-
ture of the water in the heat exchanger, the preparation of the milk is interrupted until the
minimum temperature is reached.
When the minimum operating temperature is not reached, the
display shows the following message:
Factory settings:
The minimum operating temperature is factory--set between 38
G
C and 39
G
C. The minimum
operating temperature should always be set 3
G
C below the heating temperature, in order to
avoid overlaps in the control range.
The heating temperature is factory--set between 42
G
C and 43
G
C.
The calibration menu helps you checking the water temperature.
For calibration, refer to chapter 10.4, page 54, „Functions of the Menu key, Calibration“!
