3: Compatible with TG-2000A Ver. 4.60 or later, G-50A Ver. 2.70 or later.
The data for each G-50A/GB-50A can be grouped and used to control the operation of up to 2000 units in floor or block units, etc.,
from the personal computer screen. By using a PLC or a watt-hour meter, the power rate can be apportioned, energy saving
control can be executed, and other general equipment can be controlled.

The units can be turned ON and OFF for all floors or in block, floor or group units.
The general equipment can be turned ON and OFF.
( A PLC and the general equipment control PLC software required.) 2
The operation mode can be switched between COOL, DRY, FAN, AUTO and
HEAT for all floors or in block, floor or group units.
The fan speed can be set to four stages for all floors or in block, floor or group units.
The air direction can be set in four vertical directions or to swing for all floors or in block,
floor or group units.(The selectable air direction differs according to the model.)
If there is an interlocked unit (LOSSNAY), the unit can be turned ON (strong/weak) or OFF for all floors
or in block, floor or group units. (Note that the ventilation mode cannot be selected for interlocked units.)
The annual/weekly schedule function can be used by registering the license.
Two settings, such as seasonal settings for summer and winter, can be saved.
Power rate
apportionment charging
An RS-485 watt-hour meter is connected to calculate the air-conditioning charges based on the
amount each tenant's air-conditioner has operated. Two charging rates can be applied per day.
History Up to 3000 items for the error history and up to 10000 items for operation history can be saved.
Each history file can be output as a daily report or monthly report in CSV format.
Operation time monitor The cumulative operation time of each indoor unit can be viewed or output as a CSV format file.
(This function is valid only when the charging function license is registered.)
Filter sign display
mask
Automatic display of the filter sign can be disabled. (System batch.)
In this case, the filter sign state is confirmed with manual operations .
Energy saving

Energy saving operation is possible using the "ON/OFF", "set temperature change", "fan operation
changeover" and "performance save operation" functions.

scheduling, if TG-2000A combines PLC installed with PLC software PAC-YG21CDA.
Setting inter-lock with CITY MULTI indoor units is possible.
(Table setting tool for input/output definition is needed.)
By using a PLC (with electric amount count software) and a watt-hour meter with pulse transmitter,
the air-conditioning charges can be calculated based on the amount each tenant's air-conditioner has
operated.Up to five charging rates can be applied per day. 1

By registering the G-50A unit license number, the power rate apportionment percentage data for
each indoor unit can be output in CSV format. The power rate for each tenant can be easily
calculated by having each user input the power rate manually.
The items for which operation with the local remote controller are to be prohibited can be selected for
all floors or in block, floor or group units. (The items that can be prohibited are ON/OFF, operation mode,
set temperature and filter sign reset.)
The room temperature can be set for all floors or in block, floor or group units.
