What’s Indoor Unit Automatic Address setting ?

Network between outdoor units (route between Z1 and Z2) is disconnected.

1. The outdoor unit seeks a response from all indoor units via the connected network.

2. The indoor units responds to the outdoor unit via the connected network.

3. Addresses are assigned to the indoor units recognized by the outdoor unit.

4. The outdoor unit network recovers after the Refrigerant System 1 addressing is finished.

Caution

The address is not assigned properly. (Because all indoor units have been recognized as

Refrigerant System 1.)

*An error will occur if there are more than 48 indoor units.

*An error will not occur if there are 48 or fewer indoor units,

but the address will not be assigned correctly.

Note : Precautions during automatic Address

setting

The controller unit will not run. (Because all the refrigerant systems cannot be connected.)

When Automatic Address Setting of indoor unit is performed for

refrigerant system 2, controller unit connected to refrigerant

system 1 (system controller, touch panel, etc.) cannot control

refrigerant system 3 unit.

Transmission line

The address can be assigned.

(It will take about 10 to 30 min.)

■ Separation of Transmission line

Separate on the terminal for

transmission line.

Branch the transmission line as required by the

indoor unit side.

Transmission line

Connection of three or more lines may

cause poor communication for one

terminal. In this case, please use a

terminal box.

Bad Example

Do not use loop wiring.

This may lead to parts

damage

and erroneous

operation.

(Because the signal

will conflict and cause

the power to increase.)

Attenuation

Signal attenuation continues without a signal amplifier.

If the signal output entering the signal amplifier is

low, the microcomputer removes the noise

component from the signal. Therefore, the signal is

not output from the signal amplifier.

■ Role of the Signal Amplifier (UTY-VSGX)

Communication reliability improvement

① Regenerate the signal output

② Divide LonWorks® Network (Segment)

･Insufficient Neuron chip drive

capacity

･Signal quantity increases

(signal opportunity) and possibility

of collision increases.

･The number of Neuron chip is kept

within capacity of drive.

･Possibility of collision is decreased.

This is because dividing into

segments decreases the number of

nodes within a segment.

Terminal Resistor


25

①The signal is reflected from the terminal device to become the noise component.

②If the reflected noise interferes with another signal, it disrupts the signal waveform.

③The disrupted waveform signal is not correctly recognized by the product.

In addition, since the output increases, there is a possibility the signal circuit board will be

damaged.

A terminal resistor to absorb the noise component is required to maintain overall network

signal reliability.

①

②

③

Be sure to set the terminal resistor according to specifications.

Set the terminal resistor for every network segment (NS).

● If terminal resistor is set in multiple devices, the overall communication system may be damaged.

● If terminal resistor is not set in a device, abnormal communication may occur.
