17.1 CHANGING THE SET VALUE
To change the set value the P-key has to be pushed < 2 sec. The company fixed value of 5°C
appears. With the two arrow keys the value can be changed. This value should not be adjusted lower
than +1°C, because otherwise the heat exchanger will freeze up. Is the value adjusted higher than the
ambient temperature the cooler will not work.
17.2 CHANGING THE TEMPERATURE ALARM WINDOW
The exact description of changing the temperature alarm window can be found in the manual of the
temperature controller.
