MANUAL OPERATION (ΜΑΝ)
In this mode of operation the only setting that can be adjusted is the blower speed. With the keys “+“ (4) and “-“ (3) we can select the desired speed which is steady and independent of the temperature.

SEMIAUTOMATIC OPERATION (SEMI)
It is basically the same operation as the manual operation mode with the only difference that the blower operates only when the temperature of the hot air is higher than the activation temperature .

AUTOMATIC OPERATION (AUTO)
In this mode of operation, the speed of the blower is automatically adjust depending on the temperature of the hot air. The speed is minimum when the hot air temperature exceeds the activation temperature , and gradually increase until is reaches it’s maximum value. The buttons “+“ and “-“ do not operate. If no button is not pressed for 3” during the setting mode, the device will automatically show the initial screen with the temperature of the hot air while simultaneously storing the settings. The buttons“+“ and “-“ , have a repetition function.
