The standard value of the limit current is shown in the table below.
U-4LE2E5, U-5LE2E5, U-6LE2E5
Demand control is performed to suppress the horsepower not to make the primary current exceed the setting
value.

When the Energy Saving button of the indoor unit remote controller is pressed, demand control is performed
according to EEPROM : 1A values.
The marking “ ” indicated in the following table is applicable to the function of control.
Setting of Energy Saving button: Outdoor unit EEPROM Setting item DN18, DN19
Energy saving operation when the Energy Saving button is pressed provides 3 patterns of control.
Patterns:

Pattern “A”: demand control and discharge air
temperature control
Demand control is performed under the current limitation values set at the outdoor unit EEPROM setting
(DN1A).
In addition, the indoor unit controls the limitation of discharge air temperature.
Demand control is performed under the current limitation values set at the outdoor unit EEPROM setting
(DN1A).
Discharge air temperature limitation control is performed set at the indoor unit EEPROM setting.
Outdoor unit EEPROM setting (DN18) :
A.

C.
Outdoor unit EEPROM setting (DN19):
Setting of control validity range when pressing the Energy Saving button
* When the pattern “A” and “B” are selected, energy saving control becomes valid in the same range as
the setting “1” although the Setting No. is set to “0”.
Setting No.

Energy saving activates where Energy Saving button is pressed as a unit of indoor
unit (group).
Energy saving activates where Energy Saving button is pressed as a unit of indoor
unit including all refrigerant system.
