OPERATING TIPS
Heating Performance*
●
This air conditioner operates on the heat-pump principle,
absorbing heat from outdoor air and transferring that heat
indoors. As a result, the operating performance is reduced
as outdoor air temperature drops. If you feel that insuf
fi
cient
heating performance is being produced, we recommend
you use this air conditioner in conjunction with another kind
of heating appliance.
●
Heat-pump air conditioners heat your entire room by recir-
culating air throughout the room, with the result that some
time may be required after
fi
rst starting the air conditioner
until the room is heated.
When Indoor and Outdoor Temperature are High*
When both indoor and outdoor temperatures are high during
use of the heating mode, the outdoor unit’s fan may stop at
times.
Microcomputer-controlled Automatic Defrosting*
●
When using the heating mode under conditions of low out-
door temperature and high humidity, frost may form on the
outdoor unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this
unit is equipped with a microcomputer-controlled automatic
defrosting function. If frost forms, the air conditioner will
temporarily stop, and the defrosting circuit will operate brief-
ly (Max. 15 minutes).
During automatic defrosting operation, the OPERATION
indicator lamp (green) will
fl
ash.
●
After heating operation stops, if frost forms on the outdoor
unit, the unit will start automatic defrosting operation.
At this time, the outdoor unit will automatically stop after op-
erating for a few minutes.
Low Ambient Cooling*
When the outdoor temperature drops, the outdoor unit’s fans
may switch to Low Speed, or one of the fans may stop inter-
mittently.
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
**Dual Remote Controllers (optional)
An additional remote controller can be added up to the maximum of 2 remote controllers. Either remote controller can control the air
conditioner. However, the timer functions cannot be used at the secondary unit.
**Group Control
1 remote controller can control up to 16 air conditioners. All of the air conditioners will be operated with the same settings.
Group control cannot be used when using it by the multi type.
The wired remote controller option is required to use the following function (**).
