16.1 CHANGING THE SET VALUE
For changing the set value, you must press the P-button < 2s. The set value adjusted at the factory at
5°C is shown. With both arrow keys, the set value can be set upwards or downwards. However, this
value should not be adjusted below +1°C, otherwise you must expect a freezing up of the heat
exchanger. If you set the value above the ambient temperature, the cooler will not work.
