OPERATING TIPS
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Low Ambient Cooling
l When the outdoor temperature drops, the outdoor unit’s
fans may switch to Low Speed, or one of the fans may
stop intermittently.
About ECONOMY OPERATION
In case of single-type air conditioner at the maximum output,
ECONOMY OPERATION is approximately 70% of normal air
conditioner operation for cooling and heating.
During ECONOMY OPERATION, the thermostat setting
automatically changes according to the temperature to avoid
Unnecessary cooling and heating for the most economical
operation.
l In that time, the airfl ow may be weakened or indoor fan
may be stopped in sometime. If the room is not cooled
(or heated) well during economy operation, select normal
operation.
l In case of multi-type air conditioner, the economy
operation mode is only available for the set indoor unit.
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.
Group Control
One remote controller can control up to 16 air conditioners.
All of the air conditioners will be operated with the same
settings.
*Heating Performance
l 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
insuffi cient heating performance is being produced, we
recommend you use this air conditioner in conjunction
with another kind of heating appliance.
l Heat-pump air conditioners heat your entire room by
recirculating 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
l 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
l When using the Heating mode under conditions of low
outdoor temperature and high humidity, frost may form
on the outdoor unit, resulting in reduced operating per-
formance.
In order to prevent this kind of reduced performance,
this unit is equipped with a Microcomputer-controlled
Automatic Defrosting function. 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.
l 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
operating for a few minutes.
(However, some type of multi-type air conditioner doesn't
provide this function.)
