OPERATING TIPS
Operation and performance
About priority state and standby state
● Multiple indoor units can be connected within the same system. Depend-
ing on the system, choice of operating mode are limited.
Cooling priority state:
When the other indoor units within the same system operate in cooling or
dry mode, heating cannot be selected at the same time.
Heating priority state:
When the other indoor units within the same system operate in heating
mode, cooling and dry mode cannot be selected at the same time.
Standby state:
The standby state activates when 2 or more indoor units start up at the
same time in different mode. Any indoor unit other than priority mode will
wait in standby state until priority mode changes (operation starts as soon
as priority is switched).
At this time, the Operation indicator lamp (green) will turn on and the
Timer indicator lamp (orange) will blink. (Limited to only when the IR
receiver unit is connected)
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 intermittently.
Heating performance
● Heating mode 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 type of heating appli-
ance.
● Heating mode 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.
Automatic defrosting
● When using the Heating mode under conditions of low outdoor air tem-
perature 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 Automatic defrosting function. If
frost forms, the air conditioner will temporarily stop, and the defrosting
circuit will operate briefl y (for about 4 to 15 minutes).
During the Automatic defrosting operation, the Operation indicator lamp
(green) will blink. (Limited to only when the IR receiver unit is connect-
ed.)
Oil recovery operation
● Periodically, the Oil recovery operation is performed in order to return
compressor oil to the outdoor unit.
During Oil recovery operation, the Operation indicator lamp (green) will
blink (for about 10 minutes). (Limited to only when the IR receiver unit is
connected.)
