This feature will show energy-saving effect in terms of CO
is set to [ECO1] or [ECO2]. This feature is called as [CARBON METER].
There are two messages: [TOTAL CARBON SAVINGS] and [CARBON SAVINGS-SESSION]. The [TOTAL CARBON
SAVINGS] message shows the total amount of CO
check the information on [USAGE TIME] from [INFO.] of the menu. (→ page 65)
The [CARBON SAVINGS-SESSION] message shows the amount of CO
changing to ECO MODE immediately after the time of power-on and the time of power-off. The [CARBON SAVINGS-
SESSION] message will be displayed in the [POWER OFF/ ARE YOU SURE?] message at the time of power-off.
TIP:
• The formula as shown below is used to calculate the amount of CO
Amount of CO emission reduction = (Power consumption in [OFF] for [ECO MODE] − Power consumption in [ECO1]/[ECO2] for

• The [TOTAL CARBON SAVINGS] is calculated based on savings recorded in 15 minutes intervals.
• This formula will not apply to the power consumption which is not affected by whether [ECO MODE] is turned on or off.
