INSTALLATION PRECAUTIONS ❚

DANGER

The central control must be installed by your dealer or a qualifi ed professional.

It is not advisable to install the central control yourself, as faulty handling may cause electric shock or fi re.

CAUTION

Make sure to perform grounding work. Depending on the place of installation, a leakage breaker

may be necessary.

Do not connect the ground wire to any gas pipes,
water pipes, lightning conductors or a ground wire
connected to telephones. Incomplete grounding may
cause electric shock.

If a leakage breaker is not installed, electric shock may
happen.
Consult your dealer.

OPERATION PRECAUTIONS ❚

DANGER

If the central control is damaged with water due to a
natural disaster such as a fl ood or a typhoon, consult
your dealer.

If the central control is under abnormal conditions, stop
the operation, turn the power supply switch off and consult
your dealer.

Operating the central control under such conditions
may lead to failure, electric shock and/or fi re.

Continuing operating the central control under abnormal
conditions may lead to failure, electric shock and/or fi re.

CAUTION

Do not handle with wet hands. Do not pull the connecting wire. Do not wash the central control with

water.

This may cause an electric shock
or failure.

If the core wire is disconnected,
it could cause a short-circuit.

It may cause electric shock or
failure.

A static electric discharge to the unit could cause a break-down.

Before performing operations, touch a grounded metal object and discharge any static electricity.

– 3 –

PRECAUTIONS FOR RELOCATION OR REPAIR ❚

DANGER

Never modify or disassemble the central control. If it
requires service, consult your dealer.

If it is required to relocate the central control, consult
your dealer.

If servicing is inadequate, electric shock and/or
fi re may occur.

Improper installation of the central control may cause
electric shock and/or fi re.

The energy consumption calculated by this unit does not conform to OIML, and there are no guarantees
concerning the results of the calculations.
This unit calculates only energy consumption distribution (gas, electric power). You need to calculate

Demand: · A unit that shifts its set temperature by 2 deg C or switches to fan mode when there is an

external demand input, and then cannot be operated from the remote controller.

Note

By the demand input, it is possible to save on power costs by reducing the power consumption.
Operation of the unit when demand input is released, is conformed to nearest schedule before release time
of the day.

page 43

In case schedule of the day is not set, the unit is for the operation mode and remote controller permission/
prohibition setting which is just before the demand input.
Up to three demand levels can be set. In level 1, the set temperature of the air conditioner set to D1 shifts by
2 deg C (+2 deg C in cooling or dry mode or -2 deg C in heating mode). In level 2, the units set to D1 or D2
switch to fan mode. In level 3, the units set to D1, D2, or D3 switch to fan mode.

To use the demand control, a demand signal must be inputted. For more information, contact your installation *
contractor or dealer.

Attention

If an unconnected air conditioner is registered in a group, a “Communication error” may occur, affecting
communication of the whole system and causing an unintended operation to be performed. Do not register
unconnected units in a group.
Also note that, at the initial setting, one air conditioner is registered in one group in advance. If the unit is
an unconnected unit, it must be deleted individually. It is recommended that, when registering new groups,
you press the “DELETE ALL GROUPS” button to delete all groups once, and then register groups for
connected units. That certainly is an easier way to confi gure the settings as well as a sure method to prevent
communication errors.
