Recommended tempering media
› Water (up to 80 °C)
› Low viscosity silicone oils (50 mPas) with a flashpoint ≥ 260 °C
/// Area of use
� Indoor environments similar to that a laboratory of research, teaching, trade or industry area�
� The safety of the user cannot be guaranteed:
› if the device is operated with accessories that are not supplied or recommended by the
manufacturer,

� Observe the ambient conditions (temperature, humidity, etc�) listed under “Technical data”�
�The unit is ready for service when the mains plug has been plugged in�
� Prior to commissioning the device, determine the filling quantity of the tempering medium due
to the used evaporator piston size (approx� 2�5 l tempering medium by using a standard 1 l
evaporator piston)�
� Switch on the device using the mains switch�
� At every start, the display will show all display segments (Fig� 2), the software version (Fig� 3),
and the operating mode (Fig� 4)�
� The heating bath temperature is held constant by the control circuit and is additionally monito-
red by the safety circuit�
In the event of an error occurred in the control circuit, the heating bath is switched off perma-
nently by the safety circuit�
An error in the control or safety circuits is shown on the display�
The heating function can no longer be started�
� When switching off the heating function and the medium temperature is higher than 50 °C,
the display will alternately show the set temperature (Fig� 5) and “HOT” (Fig� 9)� Otherwise, the
display will alternately show the set temperature (Fig� 5) and OFF (Fig� 8)�
When switching on the heating function, the display will alternately show set temperature (Fig�
5) and the actual temperature (Fig� 6 or Fig� 7)�

/// Safety temperature
/// Controlling the medium temperature
The safety circuit prevents the temperature of the heating bath from getting too high as a result
of controller error� Once the safety temperature has been reached, the device switches off per-
manently�
Furthermore, dry running of the heating bath is detected� The device switches off permanently�
The dry running function detects both accidental heating of the heating bath without liquid and
dry running caused by water evaporation starting at a set temperature of 60 °C� The error message
E26 (Fig� 11) appears and the heating bath is switched off permanently� To remedy this error, see
“Error codes”�
The medium temperature is limited by the set safety temperature controlled by means of a PID
controller and measured by the PT 1000 temperature sensor, and the medium is heated up as
quickly as possible without overshooting to the set temperature�
The PID controller adapts to the different tempering media and ensures optimum temperature
control with minimum temperature drift and fluctuation�
Optimum control is only achieved when the medium is mixed using a rotating evaporator piston�
� Set the desired medium temperature between room temperature and 99 °C by turning the
rotating / pressing knob�
� Start the heating function by pressing the rotating / pressing knob�
� The LED heating appears�
� The heating bath is heated up to the set temperature�
� The set and actual temperature referred to the medium are shown on the display�
