Functions
B.
C. Together with integrated centralized control software
TG-2000A, and/or PI, DIDO controller, many optional
functions like "Charging", "Peak-cut", "Energy saving",
"General equipment management", "Scheduling" etc,
can be carried out. Details, please refer to sections of
TG-2000A and/or PI, DIDO controller, PLC software.
D. One EW-50E can control maximum 50 units (including
LOSSNAY). Up to 200 units (including LOSSNAY) can
be controlled from one AE-200E connected with four
expansion controllers (AE-50E/EW-50E).
Up to four expansion controllers can be connected to
one AE-200E with Ver.7.2 or later. When four expansion
controllers are connected, the air conditioning units
cannot be connected to AE-200E.
The integrated centralized control software TG-2000A
can manage maximum 2000 units (including LOSSNAY).
For details, refer to TG-2000A page.

T
aking advantage of AE-200E's Web functions,
alarming E-mail containing address and error code can
be sent to appointed E-mail address upon any fault
happen at the air conditioner system.
This could release standby personnel and save operation cost.
The interlock-control option enables interlocked operations of
air conditioning unit groups and the general equipment groups,
based on the changes of status in the ON/OFF
, Mode, or Error
signals.(Can be set from the Web browser only)
The centralized controller of EW-50E combines Web
function, which enable the air conditioner system
management on a PC browser screen. *1
The management even carried out at a long distance
place via public telephone line or internet.
Switches between Cool/Dry/Auto/Fan/Heat. (Group of LOSSNAY
unit: automatic ventilation/vent-heat interchange/normal
ventilation)
Operation modes vary depending on the air conditioner unit.
Auto mode is the City Multi R2 and WR2 series only
.
Range of temperature setting
This function helps keep the indoor temperature in the
temperature range while the units are stopped and during the
time this function is effective.
Individually prohibit operation of each local remote control
function (ON/OFF
, Change operation mode, Set temperature,
Reset filter). Air Direction, Fan speed, Timer
*3: The settable items vary depending on the models.
When an error is currently occurring on an air conditioner unit,
the afflicted unit and the error code are displayed.
*4: When an error occurs, the "ON/OFF" LED flashes. 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.
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".
By using accessory cables you can set and monitor the following.
Input: By level signal: "Batch ON/OFF", "Batch emergency stop"
By pulse signal: "Batch ON/OFF", "Enable/disable local remote
controller"
Output: "ON/OFF", "Error/Normal"
*6: Requires an external I/O cable (PAC-YG10HA-E; sold separately) and a
commercially available external power supply.
Range of temperature settings vary depending on model.
Cool/Dry
:

This function shifts the preset temperature by the preset
increment to reduce the temperature difference between the
indoor and outdoor air temperatures during cooling operation.
The maximum shifting temperature (±1 , ±2 , ±3 , ±4 )
can be set for each group.
NOTE: Depending on the versions of EW-50E, some of the functions may not be available.
The external input/output terminal on AE-200E becomes unavailable when AE-200E is
connected to EW-50E. Use the terminals on EW-50E in that case.
* AE-200E connected with AE-50E cannot be connected to the PLC (PAC-YG21CDA).
* Contact your local distributor for which version of TG-2000A supports EW-50E.
*5 When setting ventilation interlock with Mr.Slim units, the air conditioning
and interlocked ventilation icon will display ON even when the interlocked
LOSSNAY is operating by itself.
(This will occur when used with the following M-NET adapter:
PAC-SF48/50/60/70/80/81MA-E)
Annual/Weekly (5 types)/Today schedule can be set for each
group of air conditioning units.
Optimized start setting is also available.
*2: 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.
Measures the intake temperature of the indoor unit.
*8: 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.
T
emp range limit

Sets the temperature range for the local remote controllers.
*7: The item and range that can be operated or monitored depend on
the function of the indoor unit.
AHC status
Displays the status of input and output ports of each Advanced
HVAC CONTROLLER (AHC).
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.
Outdoor Unit
Status Monitor
Monitor the current outdoor unit status
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.
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.
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.)
Data back-up (PC)
The initial setting data, operation data (charge parameter, power
consumption data) can be stored in the PC.

A.
The use of EW-50E 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.
