Whenit is OFF, all functions are disconnected but the control is stillpowered at 230V.If the frost protection function is selected by the specialmicroswitch, this function is active even if the control is off.MODE this button is used to manually switch from cooling toheating mode and vice versa. The automatic operating modeis also available: the heating or cooling mode are automaticallyselected by the microprocessor depending on the externaltemperature.FAN this button is used to select the fan speed manually (low,medium and high speed).Keep on pressing this button to select the automatic fan speedselection, which is controlled by the microprocessor. If thisoperating mode is selected, the yellow LED is on. Moreover, byusing the same button it is possible to select the Energy Savingfunction where the room temperature required is raised by 4°Cin cooling mode and reduced by 4°C in heating mode. The greenLED is on when the Energy Saving mode is active.Fig. 6Fig. 7
