OPERATING TIPS
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 to economically
control the operation of the unit.
• If you press the ENERGY SAVE button while the unit is
in the timer mode, the unit will go into the conservation
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.
During cooling operation
When the ENERGY SAVE is
pressed, the thermostat setting
is automatically raised 2 °F every
60 minutes, until the thermostat
is raised a total of 4 °F.
During heating operation
When the ENERGY SAVE is
pressed, the thermostat setting
is automatically lowered 2 °F
every 30 minutes, until the
thermostat is lowered a total
of 8 °F.

Hot start (for heating)
The indoor unit prevents cold drafts when heating operation
begins.
The indoor unit fan will not operate or it will operate at a
very low speed until the heat exchanger reaches the set
temperature.
Defrosting (for heating)
When the outdoor temperature is low and the humidity
high, frost will collect on the outdoor unit, reducing heater
effi ciency.
When this happens, the computer will automatically start
the defrost cycle. During the defrost cycle, the indoor fan
will shutdown and will be displayed on the remote
controller. It will take anywhere from 4 to 15 minutes before
the air conditioner starts up again.
Group Control
One remote controller can control up to 16 air conditioners.
All of the air conditioners will be operated with the same
settings.
Dual Remote Controllers (optional)
An additional remove controller can be added up to
the maximum of two remote controllers. Either remote
controller can control the air conditioner. However, the timer
functions cannot be used at the slave unit.
