The integrated software sets the following energy saving items and energy saving time to G-50A
per operation block. G-50A conducts energy saving operation to the indoor units with the set
detail.
1 Temperature control (±2°C)
2 Fan control (Thermostat ON)
3 Stopping control
For the block with temperature difference between set and inlet temperature exceeding the set,
the energy saving control set at level 0 is not applied.
The integrated software sets the following energy saving items and energy saving time to G-50A
per outdoor unit and the set G-50A conducts the energy saving operation for the outdoor unit.
Connecting the watt-hour meter (PLC) allows conducting energy saving operation meeting the
power consumption. The control object and detail are same as that of the energy saving rotated
control. One set of the watt-hour meter can be set for each G-50A.
During the energy saving control, the energy saving mark is displayed on the air conditioner
group icon of Web, integrated software.
Daily power consumption and control level can be monitored by the integrated software. G-50A
can hold the data for 3 days max. including that of today, yesterday and the day before yesterday.
Monthly power consumption can be monitored by the integrated software (for 62 days max.).
The integrated software monitors from PLC for display and storing.

Daily report and monthly report are the function only effective when “Energy saving peak cut control license” is registered.
To collect the energy saving status and history data, TG-2000A is required always to operate. The automatic output CSV file of daily/monthly
reports can be stored for 2 years maximum.
