1. Safety precautions
►Observe these precautions carefully to ensure safety.
►After reading this manual, pass the manual on to the end user to retain for future
reference.
►The user should keep this manual for future reference and refer to it as necessary. This
manual should be made available to those who repair or relocate the units. Make sure
that the manual is passed on to any future air conditioning system user.
: indicates a hazardous situation which, if not avoided, could result in
death or serious injury.
: indicates a hazardous situation which, if not avoided, could result in
minor or moderate injury.
: addresses practices not related to personal injury, such as product
and/or property damage.
1-1. General precautions
Do not install the controller in areas where large amounts of oil, steam, organic solvents, or
corrosive gases (such as ammonia, sulfuric compounds, or acids), or areas where
acidic/alkaline solutions or special chemical sprays are used frequently. These substances
may significantlyreduce the performance and corrode the internal parts, resulting in
electric shock, malfunction, smoke, or fire.
To reduce the risk of short circuits, current leakage, electric shock, malfunction, smoke, or
fire, do not wash the controller with water or any other liquid.
To reduce the risk of electric shock, malfunction, smoke, or fire, do not touch the electrical
parts, USB memory, or touch panel with wet fingers.
To reduce the risk of injury or electric shock, before spraying a chemical around the
controller, stop the operation and cover the controller.
To reduce the risk of injury, keep children away while installing, inspecting, or repairing the
controller.
If you notice any abnormality(e.g., burning smell), stop the operation, turn off the
controller, and consult your dealer. Continuing the operation may result in electric shock,
malfunction, or fire.
Properly install all required covers to keep moisture and dust out of the controller. Dust
accumulation and the presence of water may result in electric shock, smoke, or fire.
To reduce the risk of fire or explosion, do not place flammable materials or use flammable
sprays around the controller.
To reduce the risk of electric shock or malfunction, do not touch the touch panel, switches,
or buttons with a sharp object.
To avoid injury from broken glass, do not apply excessive force to the glass parts.
To reduce the risk of injury, electric shock, or malfunction, avoid contact with the sharp
edges of certain parts.

Consult your dealer for the proper disposal of the controller.Improper disposal will pose a
risk of environmentalpollution.
1-2. Precautions for relocating or repairingthe unit
The controller must be repaired or moved only by qualified personnel. Do not
disassemble or modify the controller.Improper installationor repair may result in injury,
electric shock, or fire.
1-3. Additional precautions
To avoid discoloration,do not use benzene, thinner,or chemical rag to clean the controller.
When the controller is heavily soiled, wipe the controller with a well-wrung cloth that has
been soaked in water with mild detergent, and then wipe off with a dry cloth.
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction concerninguse of the appliance by a person
responsiblefor their safety. Children should be supervised to ensure that they do not play
with the appliance.

[1] Safety when performing service work
Be sure to carefully read "Safety Precautions" at the beginning of this manual and perform service work while
paying attention to safety.
To ensure inspection and replacement work is performed safely, observe the following precautions when performing the work.
Before replacing parts, be sure to turn off the breaker in the control panel and the main breaker outside the
control panel to shut off the power supply to the AE-200/AE-50/EW-50.
If inspection work must be performed while the equipment is energized, do not touch live parts and take
sufficient precautions against electric shock.
Use appropriate tools for inspection and replacement work.
Using worn out tools may result in an accident due to inadequate tightening, contact failure, etc.
Be sure to ground the equipment. Furthermore, inspect the grounding state and perform the work again if
the grounding is inadequate.
After performing the inspection and replacement work, clean the equipment and the area around the
equipment and then notify the customer that the inspection and replacement work is complete.

(5) Operation block setting restrictions
・An operation block is a collection of groups, and groups of different models (air-conditioning units, LOSSNAY, general equipment,
etc.) can even be setin thesame operation block.
・An operation block that spans AE-200/AE-50/EW-50 systems cannot be set.
・The operation items differ so we recommend setting operation blocks separately for each of the indoor units, LOSSNAY units,
and A-control models.
・When peak-cut control is used, blocks become the setting target unit so be sure to set the operation blocks.
(6) Energy management block setting restrictions
・An energy management block is a collection of operation blocks and OA Processing unit (with interlock control), and operation
blocks of different models (air-conditioning units, LOSSNAY, general equipment, etc.) can also be set in the same energy
management block.
・An energy management block that spans multiple AE-50/EW-50 in an AE-200 system can be set, but an energy management
block cannot span multiple AE-200 systems.
・When the apportioned electricity billing function is used, energy management blocks become the apportioning target unit so be
sure to set the energy management blocks.

[2] System Connection Examples
The following shows the equivalent power supply of the AE-200/AE-50/EW-50 and transmission line power supply unit and the
equivalent power consumption and the equivalent number of units of the DIDO controller, PI controller, and AI controller.
Leave the power jumpers (CN41) of the outdoor units that are connected to M-NET centralized control transmission lines all
connected to the CN41 in the same wayas they were connected at the time of shipment.
If the equivalent power supply is insufficient because system remote controllers and other equipment are connected to the M-NET
centralized control transmission lines, transmission line power supply units need to be added.
When connecting system remote controllers and other equipment to the M-NET centralized control transmission lines, make sure
that the equivalent number of units total will be 40 or less.
If the equivalent number of units will exceed 40, add transmission line power supply units so that theequivalent number of units will
be 40 or less.
To supply M-NET power from a transmission line power supply unit, disconnect the CN21 jumper from the AE-200/AE-50/EW-50.
NOTE:
○If you remove the service cover from theback ofthe unit, you willfind the power jumper (CN21) of the AE-200/AE-50 in the place
indicated in the figure below.
○If you remove the servicecover from the frontofthe unit, you will find the power jumper (CN21) ofthe EW-50 in the place indicated in

(1) When using the M-NET transmission line of the AE-200 and there are 50 or fewer air-conditioning units (apportioned electricity billing
function is not used)
With the AE200, up to 50 air-conditioning units can be monitored and operated from the unit LCD screen or aWeb browser.
Also, if the EW-50 is connected instead of the AE-200, monitoring and operation from a Web browser are possible.
・The AE-50 cannot be used on its own.

[III System restrictions and notes]

(2) When using the M-NET transmission line of the AE-200 and there are 51 or more air-conditioning units (apportioned electricity billing
function is not used)
Up to 200 air-conditioning units can be monitored and operated by using three AE-50/EW-50 expansion controllers.
・When using the Web browser function, access each AE-200/AE-50/EW-50 to perform monitoring and operation.

[III System restrictions and notes]

(3) When there are 50 or fewer air-conditioning units (apportioned electricity billing function is not used and M-NET transmission of the
AE-200 is not used)
When M-NET is connected to one AE-50 expansion controller, and AE-200 is used without using M-NET transmission line, up to 50
air-conditioning units can be monitored and operated from two AE-200/AE-50 locations.
Also, monitoring and operation from an AE-200 can be performed by connecting an EW-50 in the same way.
・When using the Web browser function, access each AE-50/EW-50 to perform monitoring and operation.
