5-5 SETTING THE MASTER REMOTE CON-
TROLLER (Refer to figure 10)
• When the system is installed as shown in figure
14 and 15, it is necessary to designate one of the
remote controllers as the master remote control-
ler.
FOR RXYQ SERIES (Refer to figure 14)
When one outdoor unit is connected with several
indoor units.
FOR REYQ SERIES (Refer to figure 15)
When one BS unit is connected with several indoor
units.
• Only the master remote controller can select
heating, cooling or automatic (only REYQ series)
operation.
• The displays of slave remote controllers show
“
” (changeover under control) and they
automatically follow the operation mode directed
by the master remote controller.
However, it is possible to changeover to program dry
operation with slave remote controllers if the system
is in cooling operation set by the master remote con-
troller, and to changeover to fan only operation.
How to designate the master remote con-
troller
Press the operation mode selector button of
the current master remote controller for 4 sec-
onds.
The display showing “
” (changeover
under control) of all slave remote controllers
connected to the same outdoor unit or BS unit
flashes.
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 desig-
nated as the master remote controller and the
display showing “
” (changeover
under control) vanishes.
The displays of other remote controllers show
“
” (changeover under control).
5-6 PRECAUTIONS FOR GROUP CON-
TROL SYSTEM OR TWO REMOTE CON-
TROLLER CONTROL SYSTEM
This system provides two other control systems
beside individual control (one remote controller con-
trols one indoor unit) system. Confirm which type of
your unit is the following system.
•
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
• Contact your Daikin dealer in case of chang-
ing the combination or setting of group con-
trol and two remote controller control
systems.
6. OPTIMUM OPERATION
Observe the following precautions to ensure the
system operates properly.
• Adjust the air outlet properly and avoid direct air
flow to room inhabitants.
• Adjust the room temperature properly for a com-
fortable environment. Avoid excessive heating or
cooling.
• Prevent direct sunlight from entering a room dur-
ing cooling operation by using curtains or blinds.
• Ventilate often.
Extended use requires special attention to venti-
lation.
• Do not leave doors and windows open. If the
doors and windows remain open, air will flow out
of your room causing a decrease in the cooling or
heating effect.
• Never place objects near the air inlet or the air
outlet of the unit. It may cause deterioration in the
effect or stop the operation.
• Turn off the main power supply switch to the unit
when the unit is not used for longer periods of
time. If the switch is on, it uses electricity. Before
restarting the unit, turn on the main power supply
switch 6 hours before operation to ensure smooth
running. (Refer to the chapter “Maintenance” in
the indoor unit manual.)
