Your NUBE has a cold water tank and a hot water tank.
To change the temperature set you just have to press the C / F button for 3 seconds and raise the temperature with the HOT button and lower it with the COOL button.
COOL: To activate the cooler, you need to press the "Cool" button and you will see a light come on next to the right thermometer on your screen. NOTE: The COOL function works when Allot is on level 3 onwards.
HOT: To activate the heater, you need to press the "HOT" button and you will see a light come on next to the left thermometer on your screen.
NOTE: It is important that the "HOT" is turned off as long as hot water is not required, since energy consumption doubles and also heat penetrates the cold water tank. The reason for this is to avoid being left ON since our idea is that your energy consumption is efficient.
