If the Peltier-tempered accessory is operated without heat exchanger or with the
heat exchanger switched off, cooling is electronically suppressed, but heating is
possible. At constant ambient temperature and with a set point setting of
approx. 5 °C above the sample chamber temperature the specified target
values can with increased control cycles be maintained with an accuracy of
0.1 – 0.2 °C. However, the control accuracies specified in the sections
"Technical Data" relate to operation with heat exchanger.
Configuring the start temperature at the temperature control unit
