CHANGING THE SET VALUE


To change the set value the P-button has to be pushed in for < 2 sec. The default value of 5 °C [41 °F] appears. With the two arrow buttons the value can be changed. This value should not be adjusted lower than +1 °C [33.8 °F], because otherwise the heat exchanger will freeze up. Is the value adjusted higher than the ambient temperature the cooler will not work.
