WARNING
Do not allow unauthorized personnel other than repair engineers to enter areas where fault
diagnosis and repair work is conducted.
Unauthorized persons may suffer injury from tools and disassembled parts.
Restricted area

Connect lead wires with crimping terminals and turn the closed end upwards to avoid
exposure to water.
Failure to perform this post-connection treatment may cause disasters, such as electricity leakage
Insulation and fire, on the client’s premises.

After repair, ensure that the assembly of disassembled parts and the connection and wiring
of removed wires are completed so as to restore them to their former state. Be careful not
to have the internal wires caught in the cover or other closures.
Assembly wiring caution A defect in assembly or wire connection may cause disasters in the client premise, such as
electricity leakage and fire.
After repair, check for insulation between the charged part and non-charged metal part
(ground terminal) using an insulation resistance tester (500 V) and ensure at least 2Ω
resistance.
Insulation check If the insulation resistance value is low, it indicates the risk of disasters, such as electricity leakage
and electric shock, on the client’s premises.
In case of performing circuit inspection while the circuit is connected to a power source (if
such condition is necessary), use rubber gloves and other measures to prevent contact
with the charged part.
Electric shock caution Otherwise, one will risk electric shock from contacting the charged part.

Upon completion of repair, ensure that there are no abnormalities.

Risks of fire, electric shock or injury may be prevented by inspection.
Turn off the breaker before performing inspection.

Check after repair

Test run the system after repair and make sure that there are no abnormalities including
smoke.
Risks of fire and electric shock may be prevented by inspection.
Repair and reinstallation must be performed by qualified professional.

Repair and Reinstall

CAUTION for Monthly Report Creation Software for Smart Manager

• Using the accumulated power meter with pulse output, this system calculates the distribution of the accumulated
power converted from pulse signal by the load ratio estimated for each air-conditioner. The result can not be used for
official purpose as the calculation is not based on the local Measurement Act.
• Even though operation time is the same, power consumption varies depending on operating conditions such as the
installation condition of the air-conditioner, the set temperature, and the outdoor temperature.
• The air-conditioner is powered on for protection, etc. even while stopped, and power is consumed. This system also
calculates power consumption while the air-conditioner is not in use.
• This system calculates the distribution of the power by load ratio estimated for each air-conditioner. The result may
differ from the actual power consumption.
• As the distribution will be calculated from total power consumption if a single power meter is installed for multiple air
conditioners, the result may be different compared with the case power meter is installed for each air conditioner.
• This system calculates the pulse output from the accumulated power meter with pulse output. The result may differ
from the actual power consumption depending on the accuracy of the power meter, especially on the low power
consuming condition such as operation OFF.
• Please note that we bear no responsibility for any damage or trouble that occurs due to this system's distribution
calculation, data loss, etc.
• This system only supports the distribution calculation of power consumption by the air-conditioner. Above conditions
have to be agreed for the use of this software.

1 PRODUCT OVERVIEW
This product is an air-conditioning control system to control and monitor the operation state of air conditioners in a
building by using a computer with the mouse at a customer site. The system enables intensive management,
operation control, and energy-saving operation for the air conditioners of up to 128 groups. The display and
operation are available on a Web browser. This does not require dedicated software to be installed in a PC, and
enables up to 4 units of PC to access simultaneously the system.

1-1. Main Functions

Monitoring / Controlling Air Conditioners
Enables users to monitor the operating status, setup status, and error status of all their air conditioners, to start and
stop all theirs air conditioners, and change the setup details of all their air conditioners.
The air conditioners are named and categorized in a hierarchy by each floor, tenant, area, and air conditioning
system. When controlling the air conditioners, they can be set in batch by each floor, tenant, or area, or they can
be set individually for each air conditioning system.
The air conditioners can be controlled by linking to the locking signals.

Scheduled Operation for Air Conditioners

Operation of all air conditioners can be scheduled. Up to 10 setups can be programmed for each day, and it is
possible to prevent users from forgetting to switch off by setting a stop schedule. During scheduled operation, users
can set the Power status (On / Off), Operation mode, Temperature setup, Remote control operation restricted /
allowed, and Return back.
In the master schedule, users can set weekly schedules and five types of special day schedules, as well as monthly
schedules for up to 12 months.

Distributing Power used by Air Conditioners

It is possible to distribute the power to be used for each air conditioner. In the billing schedule setup, it is possible
to monitor the operation time period and power distribution during both working hours and non-working hours
separately.
Note that power distribution requires the Energy Monitoring Relay Interface (sold separately).

13-2.Trouble with Web Screen
(Target model of this section is Smart Manager (SM1280HTLUL) which can be connected to a PC through the Web.)

13-2-1. Takes long time to display.

No. Cause Solution
1 The network is busy. Connection via an intra-company LAN may slow the Web screen display due
to a busy network. Use the system during off-peak hours of network use, or
use a dedicated network to connect a PC with the controller.
If a 10 BASE switching HUB is used, replace it with a 100 BASE switching
HUB.
2 PC performance has degraded. If some application programs are operating other than the browser, the PC
performance may degrade. Close the operating applications other than the
browser, and check if the PC performance improves.
3 Trouble due to the browser. The supported browsers are Internet Explorer 6.0, 7.0 and 8.0 and Firefox
2.0, 3.0, 3.5 and 3.6. If a browser other than these browsers is used, the
contents may not be displayed properly. Use one of the supported browsers
to see the contents.
4 Other users are also accessing the controller. If other users are performing schedule setting or other operation, the display
switching may slow down. Wait for a while, and access to the controller again.
5 The controller is writing a file. The controller regularly writes a file for electricity distribution. The display
may slow down during the writing process.

13-2-2. Improperly returns to the logon screen.

No. Cause Solution
1 The controller performance has degraded. If the controller is accessed from a browser while the controller internal
processing is in progress, the controller performance degrades. To prioritize
controller internal processing (writing a file or giving instruction to an air
conditioner), the system once stops the access from the browser. Log on
again.

2.0, 3.0, 3.5 and 3.6. If a browser other than these browsers is used, the
contents may not be displayed properly. Use one of the supported browsers
to see the contents.
2 The controller performance has degraded. If the controller is accessed from a browser while the controller internal
processing is in progress, the controller performance degrades. To prioritize
controller internal processing (writing a file or giving instruction to an air
conditioner), the system once stops the access from the browser. At this time,
the browser may fail to display buttons or other elements.
The missing GUI elements can be displayed by refreshing the browser
window.
For Internet Explorer, click [View] and then [Refresh]. For Firefox, click [View]
and then [Reload].
3 The network is busy. Connection via an intra-company LAN may slow screen display due to a busy
network, possibly causing the display failure of those elements. Use the
system during off-peak hours of network use, or use a dedicated network to
connect a PC with the controller.
If a 10 BASE switching HUB is used, replace it with a 100 BASE switching
HUB.
The missing GUI elements can be displayed by refreshing the browser
window.
For Internet Explorer, click [View] and then [Refresh]. For Firefox, click [View]
