(3) Function list

By utilizing the software (TG-2000A) and collecting the data of each G-50A, the operation control can be performed

for up to 2000 sets in a unit of each floor or block on the PC screen.Please refer to section 2,3 for function licence.

Additionally by using PLC (Programmable Logic Controller), general equipment can be controlled in addition to the

electric power apportioning function and energy saving control.

Content

Switching start/stop for whole building, or in a unit of block, floor or group

Switching cool/dry/fan/auto/heat for whole building, or in a unit of block, floor or group.

Setting room temperature for whole building, or in a unit of block, floor or group

Set temperature range Cool/dry : 19°C ~ 30°C

Heat : 17°C ~ 28°C

Auto : 19°C ~ 28°C

Switching air velocity in 4 steps for whole building, or in a unit of block, floor or group.

Switching in 4 steps vertically and for swing for whole building, or in a unit of block, floor or group

(Selectable air direction differs depending on the model.)

Switching start (Hi/Lo)/stop for whole building, or in a unit of block, floor or group when

connecting with interlocked equipment (Lossnay). (However, ventilation mode can not be

selected for interlocked equipment.)

For whole building, or in a unit of block, floor or group, items for which local control is prohibited

can be selected. (The items include start/stop, operation mode, set temperature, filter sign reset.)

License registration allows you to use the annual/weekly schedule function.

Two seasonal setting (for summer and winter) can be used.

Through the license registration of G-50A unit, the power apportioning rate data per indoor unit

can be output in CSV format. Further by inputting the WHM amount manually, the power

consumed by each tenant can be calculated easily.

By registering license to G-50A, the air conditioning charge can be calculated through the

apportioning of power consumption based on the air conditioner operating record per tenant by

using PLC (Electric power counting software: PAC-YG11CDA) and WHM with pulse oscillation

device.

Through the registration of license number to G-50A unit, the power consumption of air

conditioner by each tenant can be calculated by using PS-485 watt-hour meter (only for the

designated models).

The abnormal history record can be stored up to 3,000 and operation history record can be

stored up to 10,000 respectively. The history record may be output as a daily and monthly record

in CSV format.

The integrated operation time of each indoor unit group*

can be observed. It can be output as a file

in CSV format. (This function is only effective when registering the charging function for license.)

The automatic display of the filter sign may be suspended. (for a whole system collectively) In

this case, the state of the filter sign can be checked by manual operation.

With the schedule by a group unit, a temperature of 12 ~ 16˚C can be set under heating mode.

However, only the M-NET indoor units are objected, while K-control and A-control indoor units

are not objected. This function is effective only for ME remote controller system.

It is possible to control the set temperature range from the hand remote controller or the browser

screen of general users. The range limits include the lower limit value at cooling and the upper

limit value at heating.

By the way, this function is available only in the ME remote control system.

By installing the general purpose control software to PLC, it is possible to schedule the operation

and stop of other manufacturers’ air conditioners and facilities, and monitor them and monitor

their error.

By registering the license number to G-50A, energy saving control is available.

By setting the control contents per block from TG-2000A, energy saving rotation operation is

carried out in unit of group.

By registering the license number to G-50A, energy saving peak cut operation is available

according to the electricity use amount. This control requires PLC (electric power amount count

software) separately, and by connecting an electric power meter, energy saving operation can be

made according to the electricity use amount.

* The above functions are subject to change for improvement without notice.

Operation time of minimum address unit is displayed in group.

Notice

●The operation prohibition settings to K control type are only operation/stop, operation

mode, and temperature setting. Whether prohibition or permission on these 3 items

cannot be set individually.

●

In the group controlling LOSSNAY, only operation/stop, and filter sign reset operation can be

set for prohibition.

● Registration of the license number is carried out in unit of G-50A from the Web screen.
