  (RXY(H)Q +

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 controllers if the system is in cooling operation set by the
master remote controller.

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 comfortable
environment. Avoid excessive heating or cooling.

Prevent direct sunlight from entering a room during cooling
operation by using curtains or blinds.

Ventilate often.
Extended use requires special attention to ventilation.

Keep doors and windows closed. If the doors and windows
remain open, air will flow out of your room causing a decrease in
the cooling or heating effect.

Be careful not to cool or heat too much. To save energy, keep
the temperature setting at a moderate level.

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 "Maintenance" in the indoor unit manual.)

When the display shows 

 (time to clean the air filter), ask a

qualified service person to clean the filters. (Refer to
"Maintenance" in the indoor unit manual.)

Keep the indoor unit and remote control at least 1 m away from
televisions, radios, stereos, and other similar equipment.
Failing to do so may cause static or distorted pictures.

Do not place items under the indoor unit which may be damaged
by water.
Condensation may form if the humidity is above 80% or if the
drain outlet gets blocked.

Maintenance after a long stop period 

(e.g. at the

beginning of the season)

Check and remove everything that might be blocking inlet and
outlet vents of indoor units and outdoor units.

Clean air filters and casings of indoor units. Refer to the
operation manual supplied with the indoor units for details on
how to proceed and make sure to install cleaned air filters back
in the same position.

Turn on the power at least 6 hours before operating the unit in
order to ensure smoother operation. As soon as the power is
turned on, the remote controller displays appear.

NOTE

Contact your dealer in case of changing the
combination or setting of group control and two remote
controller control systems.
