In a group control, operation of maximum 8 indoor units can be controlled by a remote controller.

Twin, triple or double twin of an outdoor unit is one of the group controls.

The indoor unit connected with outdoor unit (Individual/Header of twin) controls room temperature according to

setting on the remote controller.

The setup range (Operation mode/Air volume select/Setup temp) of the indoor unit which was set to the header

unit is reflected on the remote controller.

• If the Concealed duct high static pressure type is the header unit:

Operation mode: [Cooling/Heating AUTO] [HEAT] [COOL] [FAN] and no [DRY]

Air volume select: [HIGH]

• When the operation mode is [DRY], [FAN] stops in concealed duct high static pressure models.

Address setup

If there is no serial communication between indoor and outdoor when the power is turned on, it is judged as

follower unit of the twin. (Every time when the power is turned on)

• The judgment of header (wired) / follower (simple) of twin is carried out every time. It is not stored in non-

volatile memory.

Turn on power of the indoor unit to be controlled in a group within 3 minutes after setting of automatic address.

If power of the indoor unit is not turned on within 3 minutes (completion of automatic address setting), the system

is rebooted and the automatic address setting will be judged again.

1) Connect indoor/outdoor connecting wire surely.

2) Check line address/indoor address/group address of the unit one by one.

Especially in case of twin, triple, double twin, check whether they are identical system address or not.

3) The unit No. (line/indoor gout address) which have been set once keep the present status as a rule if the unit

No. is not duplicated with one of another unit.

Aiming in environmental preservation, it is strictly recommended to clean and maintain the indoor/outdoor units

of the operating air conditioning system regularly to secure effective operation of the air conditioner.

It is also recommended to maintain the units once a year regularly when operating the air conditioner for a long

time.

Check periodically signs of rust or scratches, etc. on coating of the outdoor units.

Repair the defective position or apply the rust resisting paint if necessary.

If an indoor unit operates for approx. 8 hours or more per day, usually it is necessary to clean the indoor/outdoor

units once three months at least.

These cleaning and maintenance should be carried out by a qualified dealer.

Although the customer has to pay the charge for the maintenance, the life of the unit can be prolonged.

Failure to clean the indoor/outdoor units regularly will cause shortage of capacity, freezing, water leakage or

trouble on the compressor.

WARNINGS ON REFRIGERANT LEAKAGE

Check of Concentration Limit

The room in which the air conditioner is to be installed requires a design that in the event of refrigerant

gas leaking out, its concentration will not exceed a set limit.

The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of

ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains

more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from

leakage of R410A is almost non-existent.

If a conditioner system is to be installed in a small room, select a suitable model and installation procedure so

that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an

emergency, measures can be made before injury can occur).

In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install

mechanical ventilation combined with a gas leak detection device.

The concentration is as given below.

Total amount of refrigerant (kg)

≤ Concentration limit (kg/m³)

Min. volume of the indoor unit installed room (m³)

The concentration limit of R410A which is used in air conditioners is 0.3 kg/m³.

NOTE

The minimum indoor floor area compared with the amount of refrigerant is roughly as follows:

(When the ceiling is 2.7m high)

Range below the

m235

density limit of

0.3 kg/m³

(countermeasures

not needed)

Range above the

density limit of

0.3 kg/m³

(countermeasures

needed)
