Note:

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC

Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

FCC Caution: To assure continued compliance, follow the attached installation instructions.

Any changes or modifi cations not expressly approved by the party responsible for compliance could void the user’s authority to
operate this equipment.

Inter-unit control wiring

• Up to 16 groups of indoor units (maximum 64 units) can be controlled with 1 LonWorks Interface unit.
For 17 or more groups of indoor units, connect additional interface units.

• Install a remote controller (or system controller, etc.), which can control the A/C units, to an inter-unit control
wiring other than the LonWorks Interface unit.

• Before making the connection to the LonWorks Interface unit, set the central control addresses in the indoor
units.

(*1) When a temperature above the upper limit of the temperature which can be set by the indoor units has been specifi ed,

it will be set to the upper limit; conversely, when a temperature below the lower limit has been specifi ed, it will be set to
the lower limit.

(*2) Two options can be selected using the setting switch from among remote-controller prohibit, fan speed setting, air

direction setting and fi lter sign.

(*3) When indoor units are under group control, an alarm is determined to have occurred when the alarm occurs at one or

more of the units.

(*4) The number of the indoor unit at which the alarm has occurred is notifi ed. This makes it possible to identify at which

indoor unit of the indoor unit group the alarm has occurred.
(*5) When indoor units are under group control, the room temperature of the main unit in the group is notifi ed.
(*6) When an alarm occurs at one or more indoor units, the alarm code is notifi ed as the indoor unit status.
(*7) All the data which can be output is output at the set interval.
(*8) The same data is not output continuously at the set interval.

2. Installation Instructions of LonWorks Interface

Safety Precautions

The following is intended for the installer responsible for

∗

installation and test operations of the LonWorks Interface,
and should be carefully read before beginning.
The precautions given in this manual consist of specifi c

∗

“Warnings” and “Cautions.” They provide important
safety-related information and are important for your safety,
the safety of others, and trouble-free operation of the
system. Be sure to strictly observe all safety procedures.
The labels and their meanings are as described below.

This symbol refers to a hazard or unsafe

Warning

Caution

※

After installation is completed, perform a test run to check
for operating trouble. As you do, use the central control
device Operating Instructions and explain operating
procedures to the customer. Then request that the customer
store this manual together with the central control device
Operating Instructions.

• Be sure to arrange installation from the dealer where the
system was purchased or using a professional installer.
Electric shock or fi re may result if an inexperienced
person performs any installation or wiring procedures
incorrectly.

•

Please install and ensure construction according to Installation
Instructions of LonWorks Interface.

•

Only a qualifi ed electrician should attempt to connect this
system, in accordance with the instructions in this manual.
If the electrical circuit capacity is insuffi cient a danger of
electric shock and fi re may be present.

•

Use the specifi ed cables (type and wiring diameter) for the
electrical connections, and connect the cables securely.
Run and fasten the cables securely so that external forces
or pressure placed on the cables will not be transmitted to
the connection terminals. Overheating or fi re may result if
connections or attachments are not secure.

Depending on the installation conditions and location, an earth
leakage breaker may be required. If an earth-leakage breaker
is not installed, there is a danger of electric shock or fi re.

Warning

Caution

Installation Method

• The screws used to install the main unit must be provided by
the installer.



• Install the LonWorks Interface away from any sources of
electrical noise.

Wiring Specifi cations

•

For the inter-unit control wiring use twin-core AWG#20 –
AWG#14 cables.

• For the LonWorks communication line cables, use twisted­pair cables with a wire diameter of 0.51 mm(AWG#24) or
larger as recommended by Echelon Corp.

Examples of cables recommended by Echelon Corp.

Cable type

24 AMG twisted-pair

(TIA568A category 5)

•

Do not use the same cable for the inter-unit control wiring, the
LonWorks communication lines, and the power cable. Do not
run them through the same conduit or place the cables near
one another.

• Connect the cables so that there is no miswiring.
(Miswiring can cause malfunction.)

• The LonWorks communication lines can be connected
to either (1) or (2) in the above fi gure. The results are the
same.

• Do not run the inter-unit control lines, the LonWorks
communication lines, and the power cables through the
same conduit, or place the cables near one another. Doing
so can cause the system to malfunction.

• Before turning the power on, follow the instruction in Power
Board Initial Settings.

• When using the spare inter-unit cotrol line, connect [1] and [3]
at CN002.

• When using the spare LON communication line, connect [1]
and [3] or [4] and [6] at CN003.
