OPERATING TIPS

Instructions relating to heating are applicable only to "HEAT & COOL MODEL" (Reverse Cycle).
About ECONOMY OPERATION
At the maximum output, ECONOMY OPERATION is approxi-
mately 70% of normal air conditioner operation for cooling
and heating.
When ECONOMY OPERATION is performed during the cool-
ing mode, dehumidification is improved. This function is es-
pecially convenient when you want to remove the humidity
in the room without significantly lowering the room tempera-
ture.
During ECONOMY OPERATION, the thermostat setting auto-
matically changes according to the temperature to avoid Un-
necessary cooling and heating for the most economical op-
eration.
• If the room is not cooled (or heated) well during economy
operation, select normal operation.
• During the monitor period in the AUTO mode, the air con-
ditioner operation will not change to ECONOMY OPERA-
TION even if ECONOMY OPERATION is selected by press-
ing the ECONOMY button.
Defrosting (for heating)
When the outdoor temperature is low and the humidity high,
frost will collect on the outdoor unit, reducing heater efficiency.
When this happens, the computer will automatically start the
defrost cycle. During the defrost cycle, the indoor fan will shut-
down and will be displayed on the remote controller. It
will take anywhere from 4 to 15 minutes before the air condi-
tioner 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 set-
tings.
Dual Remote Controllers (optional)
An additional remove controller can be added up to the maxi-
mum of two remote controllers. Either remote controller can
control the air conditioner. However, the timer functions can-
not be used at the slave unit.

of the outdoor unit will be determined by the operating
mode of the indoor unit that was operated first. If the in-
door unit was started in fan mode, the operating mode of
the outdoor unit will not be determined.
For example, if indoor unit (A) was started in fan mode
and then indoor unit (B) was then operated in heating
mode, indoor unit (A) would temporarily start operation
in fan mode but when indoor unit (B) started operating in
heating mode, will be shown on the remote con-
troller display and it would go into standby mode. Indoor
unit (B) would continue to operate in heating mode.
