Energy saving index
The energy saving index is calculated based on the setting of your program. It is used as a reference for the user to know how likely the program is to conserve energy or consume more. If the user sets a comfort program setting, the appliances are likely to be turned on a lot and “LOSE” may be shown on the screen. If the appliances are less likely to be turned on, “SAVE” may be shown on the screen. The likelihood of saving energy or losing energy is converted to a percentage value for reference. If the value is higher than 99%, “HI” will be shown instead.
