Operation manual
5
For systems with cool/heat changeover remote control switch
(See figure 6)
1 Select cooling operation mode with the cool/heat changeover
remote control switch.
2 Press the operation mode selector button several times and
select (program dry operation).
3 Press the on/off button.
The operation lamp lights up and the system starts operation.
4 Press the air flow direction adjust button. (Only for Double-flow,
Multi-flow, Corner, Ceiling-suspended and Wall-mounted.) Refer
to "7.3. Adjusting the air flow direction" on page 5 for details.
Stopping the system
5 Press the on/off button once again.
The operation lamp goes off and the system stops operation.
7.3. Adjusting the air flow direction
Refer to the operation manual of the remote controller.
Movement of the air flow flap (See figure 8)
For the following conditions, a micro computer controls the air flow
direction which may be different from the display.
The air flow direction can be adjusted in one of the following ways.
■ The air flow flap itself adjusts its position.
■ The air flow direction can be fixed by the user.
■ Automatic " " and desired position " ".
7.4. Setting the master remote controller
When the system is installed as shown in figure 9 (RXY(H)Q +
RXYRQ + RXHQ + RXYSQ – the outdoor unit is connected to
several indoor units) and figure 10 (
REM(H)Q + REY(H)Q
– one BS
unit is connected to several indoor units), it is necessary to
designate one of the remote controllers as the master remote
controller.
■ Only the master remote controller can select heating or cooling
and in case of REM(H)Q + REY(H)Q units, automatic operation.
■ The displays of slave remote controllers show (change-
over under centralized control) and slave remote controllers
automatically follow the operation mode directed by the master
remote controller.
However, it is possible to changeover to program dry with slave
remote controllers if the system is in cooling operation set by the
master remote controller.
How to designate the master remote controller
1 Press the operation mode selector button of the current master
remote controller for 4 seconds.
The display showing (change-over under centralized
control) of all slave remote controllers connected to the same
outdoor unit or BS unit flash.
2 Press the operation mode selector button of the controller that
you wish to designate as the master remote controller. Then
designation is completed. This remote controller is designated
as the master remote controller and the display showing
(change-over under centralized control) vanishes.
The displays of other remote controllers show (change-
over under centralized control).
7.5. Precautions for group control system or two
remote controller control system
This system provides two other control systems beside individual
control (one remote controller controls one indoor unit) system.
Confirm the following if your unit is of the following control system
type.
■ Group control system
One remote controller controls up to 16 indoor units. All indoor
units are equally set.
■ Two remote controller control system
Two remote controllers control one indoor unit (in case of group
control system, one group of indoor units). The unit is
individually operated.
NOTE
Do not turn off power immediately after the unit stops,
but wait for at least 5 minutes.
A Double-flow + Multi-flow units
B Corner units
C Ceiling-suspended units
D Wall-mounted units
COOLING HEATING
• When the room temperature is lower than
the set temperature.
• When starting operation.
• When the room temperature is higher than
the set temperature.
• At defrost operation.
• When operating continuously at horizontal air flow direction.
• When continuous operation with downward air flow is performed at the time of cooling with a
ceiling-suspended or a wall-mounted unit, the microcomputer may control the flow direction,
and then the remote control indication also will change.
NOTE
■ The movable limit of the flap is changeable.
Contact your dealer for details. (Only for Double-
flow, Multi-flow, Corner, Ceiling-suspended and
Wall-mounted.)
■ Avoid operating in the horizontal direction
" ". It may cause dew or dust to settle on the
ceiling.
NOTE
Contact your dealer in case of changing the
combination or setting of group control and two remote
controller control systems.
