*1: Louver cannot be set.
*Air flow direction settings vary depending on the model.
The interlocked system settings can be performed by the master system controller.
When setting the interlocked system, you can use the ventilation switch to switch the free
plan LOSSNAY settings between "Hi", "Low" and "Stop".
When setting a group of only free plan LOSSNAY units, you can switch between "Normal
ventilation", "Interchange ventilation" and "Automatic ventilation".
External Temperature
Interlock
This function shifts the preset temperature by the preset increment to reduce the
temperature difference between the indoor and outdoor air temperatures during cooling or
heating operation. The maximum shifting temperature(±1°C, ±2°C, ±3°C, ±4°C) can be set for
each group.
Schedule operation
Annual/Weekly (5 types)/Today schedule can be set for each group of air conditioning units.
Optimized start setting is also available.
*3: The system follows either the current day, annual schedule, or weekly, which are in
the descending order of overriding priority.
Twenty-four events can scheduled per day, including ON/OFF, Mode, Temperature
Setting, Vane Direction, Fan Speed, and Operation Prohibition. Five types of weekly
schedule(Summer/Winter/etc.) can be set.
Settable items depend on the functions that a given air conditioning unit supports.
Night setback setting
The function keeps the indoor temperature in a set temperature range once the unit off
and during the time this function is effective.
Permit / Prohibit
local operation
Individually prohibit operation of each local remote control function (ON/OFF, Change
operation mode, Set temperature, Reset filter sign, Air Direction, Fan speed, Timer).
Indoor unit intake
temperature
Measures the intake temperature of the indoor unit.
Interlock setting
Operation of indoor groups or general equipment can be interlocked by the change of state
(ON/OFF
, mode, error of indoor groups and general equipment). (EB-50GU will execute
interlocking control depending on the interlocked setting.)
Filter sign reset/
Filter sign
Filter sign can be reset for each group or block of indoor units.
Filter sign indicates that the filter on the units in a given group is due for cleaning.
Test run
This operates air conditioner units in test run mode.
Error
When an error is currently occurring on an air conditioner unit, the afflicted unit and the error
code are displayed.
*4: The settable items vary depending on the models.
*7: Displays the ambient temperature of either the return air temperature sensor on the
indoor unit or the temperature sensor on the remote controller, whichever is selected
on the indoor temperature display mode selection.
*1
*5: The operation monitor screen shows the abnormal unit by flashing it. The error monitor
screen shows the abnormal unit address, error code and source of detection. The error
log monitor screen shows the time and date, the abnormal unit address, error code and
source of detection.
Models with 5 air flow speed settings: Hi/Mid-1/Mid-2/Low, Auto
Models with 4 air flow speed settings: Hi/Mid/Low, Auto
Models with 2 air flow speed settings: Hi/Low
*Fan speed settings vary depending on the model.

Free Contact status
Displays the input/output status of the free contacts on the indoor units.
Measurement
Displays the temperature, humidity, and the reading of the watt-hour meter.

Data: Frequency (Compressor), high/low pressure (outdoor unit)
Energy Use Status
On the Energy Use Status screen, the energy-control-related status, such as electric energy
consumption, operation time, and outdoor temperature, can be displayed in a graph.
Operators can check the detailed status of given indoor units by specifying the date to
display the data per group, block, or unit address.
The temperature can be set within the following range.
Cool/Drying : 19°C - 35°C/67°F - 95°F
Heat: 4.5°C - 28°C/40°F - 83°F
Auto (single set point): /19°C - 28°C/67°F - 83°F
Auto (dual set points)

C. One EB-50GU can control a maximum of 50 Indoor
units (including LOSSNA
Y). The integrated
centralized control software TG-2000A (*2) can
manages maximum of 40 EB-50GU's and maximum
of 2000 units (including LOSSNA
Y).
D. T
aking advantage of EB-50GU's Web functions, alarm
E-mail containing address and error code can be
sent to appointed E-mail address upon any fault
occurring at the air conditioner system.
This could release standby personnel and save
operation costs.
E. T
ogether with integrated centralized control software
TG-2000A, and/or other controllers (DIDO, AI,
PI controller), many optional functions like "Charging",
"Peak-cut", "Energy saving" etc, can be carried out.
The centralized controller of EB-50GU combines Web
function, which enable the air conditioner system
management on a PC browser screen. *1.
The management can even be carried out remotely.
A. The use of EB-50GU combined with AHC will allow
the use of external signal, making it possible to
use integrated control of air conditioning systems
including third-party HVAC products.
