12.3. Multi-type air conditioner

NOTES: Depending on model, this function cannot be used. For details,
please consult authorized service personnel.
This indoor unit can be connected to a multi-type outdoor unit.
The multi-type air conditioner allows multiple indoor units to be
operated in multiple locations. The indoor units may be operated
simultaneously, in accordance with their respective output.
Simultaneous Use of Multiple Units
● When using a multi-type air conditioner, the multiple indoor units can
be operated simultaneously, but when 2 or more indoor units of the
same group are operated simultaneously, the heating and cooling
efficiency will be less than when a single indoor unit is used alone.
Accordingly, when you wish to use more than 1 indoor unit for cooling
at the same time, the use should be concentrated at night and other
times when less output is required. In the same way, when multiple
units are used simultaneously for heating, it is recommended that they
be used in conjunction with other auxiliary space heaters, as required.
● Seasonal and outdoor temperature conditions, the structure of
the rooms and the number of persons present may also result in
differences of operating efficiency. We recommend that you try various
operating patterns in order to confirm the level of heating and cooling
output provided by your units, and use the units in the way that best
matches your family's lifestyle.
● If you discover that 1 or more units delivers a low level of cooling or
heating during simultaneous operation, we recommend that you stop
simultaneous operation of the multiple units.
● Operation cannot be done in the following different operating modes.
If the indoor unit is instructed to do an operating mode that it cannot
perform, [ ] indicator on the indoor unit will flash (1 second on, 1 sec-
ond off) and the unit will go into the standby mode.
Heating mode and Cooling mode (or Dry mode)
Heating mode and Fan mode
● Operation can be done in the following different operating modes.
Cooling mode and Dry mode
Cooling mode and Fan mode
Dry mode and Fan mode
● The operating mode (Heating mode or Cooling (Dry) mode) of the out-
door unit will be determined by the operating mode of the indoor unit
that was operated first. If the indoor unit was started in the Fan mode,
the operating mode of the outdoor unit will not be determined.
For example, if indoor unit (A) was started in the Fan mode and then
indoor unit (B) was then operated in the Heating mode, indoor unit (A)
would temporarily start operation in the Fan mode but when indoor
unit (B) started operating in the Heating mode, [ ] indicator for indoor
unit (A) would begin to flash (1 second on, 1 second off) and it would
go into standby mode. Indoor unit (B) would continue to operate in
Heating mode.
