Cause

This is not a trouble as it is just a selecting sound.

When multiple indoor units (max. 3) are connected to the same branch of the BC

controller, the heating (cooling) operation cannot be performed while another

indoor unit is performing a cooling (heating) operation.

Because of the control operation of auto vane, it may change over to horizontal

blow automatically from the downward blow in cooling in case the downward

blow operation has been continued for 1 hour. At defrosting in heating, hot adjust-

ing and thermostat OFF, it automatically changes over to horizontal blow.

Ultra-low speed operation is commenced at thermostat OFF.

Light air automatically changes over to set value by time or piping temperature at

thermostat ON.

The fan is to stop during defrosting.

Fan is to run for 1 minute after stopping to exhaust residual heat (only in heating).

Ultra low-speed operation for 5 minutes after SW ON or until piping temperature

becomes 35

°

C, low speed operation for 2 minutes thereafter, and then set notch

is commenced. (Hot adjust control)

When the heat source unit is being cooled and the refrigerant is resting, warming

up operation is performed for at least 35 minutes to warm the compressor.

During this time, only the fan operates.

System is being driven.

Operate remote controller again after “HO” disappear.

After a stop of cooling operation, unit continues to operate drain pump for three

minutes and then stops it.

Unit continues to operate drain pump if drainage is generated, even during a

stop.

Phenomenon

Indoor unit and BC controller generate sound

at the cooling/heating change over sometime.

Indoor unit does not the perform cooling (heat-

ing) operation.

The auto vane runs freely.

Fan setting changes during heating.

Fan stops during heating operation.

Fan does not stop while operation has been

stopped.

No setting of fan while start SW has been

turned on.

Heat source unit does not operate by turning

switch on.

Indoor unit remote controller shows “HO” in-

dicator for about two minutes when turning

ON universal power supply.

Drain pump does not stop while unit has been

stopped.

Drain pump continues to operate while unit

has been stopped.

Thickness of Wire for Main Power Supply and On/Off Capacities

1. Use a separate power supply for the heat source unit and indoor unit.
2. Bear in mind ambient conditions(ambient temperature,direct sunlight, rain water,etc.) when proceeding with the wiring and connections.
3. The wire size is the minimum value for metal conduit wiring. The power cord size should be 1 rank thicker consideration of voltage drops.

Make sure the power-supply voltage does not drop more than 10 %.

4. Specific wiring requirements should adhere to the wiring regulations of the reglon.
5. Power supply cords of parts of appliances for heat source use shall not be lighter than polychloroprene sheathed flexible cord (design 245 IEC57).
6. A switch with at least 3 mm contact separation in each pole shall be provided by the Air conditioner installation.

 Warning:

Be sure to use specified wires to connect so that no external force is imparted to terminal connections. If connections are not fixed firmly, it may cause
heating or fire.

Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.

 Caution:

Some installation site may require attachment of an earth leakage breaker. If no earth leakage breaker is installed, it may cause an electric shock.

Do not use anything other than breaker and fuse with correct capacity. Using fuse and wire or copper wire with too large capacity may cause a malfunction
of unit or fire.
