About the ENERGY SAVE

The energy conservation mode (ENERGY SAVE) raises the set temperature slightly in the cooling mode and lowers the set
temperature in the heating mode, using a computer program to economically control the operation of the unit.

If you press the ENERGY SAVE button while the air conditioner is on, it will change to the conservation mode. If you press
the ENERGY SAVE button while the unit is in the timer mode (ON timer, WEEKLY timer), the unit will go into the conserva-
tion mode when the unit starts with the timer.

If you turn off the air conditioner while in the conservation mode, the mode will be shut off.

The temperature set on the remote controller will not change if the energy save mode is used.

* When Heating

After the ENERGY SAVE button is pressed, the set tempera-
ture will be lowered about 1 

°

C every 30 minutes. When it

has lowered a total of 2 

°

C, then it will hold that tempera-

ture.

When Cooling

After the ENERGY SAVE button is pressed, the set tempera-
ture will be raised about 0.5 

°

C every 30 minutes. When it

has gone up a total of 1 

°

C, then it will hold that tempera-

ture.
