1. Safety precautions
►Thoroughly read the following safety precautions prior to installation.
►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 significantly reduce 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.

3
WT07190X01
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 environmental pollution.
1-2. Precautions for relocating or repairing the unit
The controller must be repaired or moved only by qualified personnel. Do not disassemble
or modify the controller. Improper installation or 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 concerning use of the appliance by a person
responsible for their safety. Children should be supervised to ensure that they do not play
with the appliance.

WT07190X01
2. Introduction
AE-200A/AE-50A/AE-200E/AE-50E is a centralized controller.
Any connected air conditioning systems can be operated or monitored on the AE-200A/AE-50A/AE-200E/AE-50E’s
LCD or the Web browser. Each AE-200A/AE-50A/AE-200E/AE-50E can control up to a total of 50 indoor units and
other equipment. By connecting AE-200A/AE-200E (main controller) and AE-50A/AE-50E (sub controllers), up to
200 indoor units and other equipment can be controlled.
2-1. Terms used in this manual
- “Centralized Controller AE-200A/AE-200E” is referred to as “AE-200.”
- “Centralized Controller AE-50A/AE-50E” is referred to as “AE-50.”
- “Booster unit” and “Water HEX unit” are referred to as “Air To Water (PWFY) unit.”
- “Advanced HVAC CONTROLLER” is referred to as “AHC.”
- “Hot Water Heat Pump unit” is referred to as “HWHP (CAHV) unit.”
2-2. Required licenses
The required licenses vary, depending on the functions to be used. Refer to the License Classification List for
details. Purchase the required licenses from your dealer. Refer to section 5-2-4 for license registration.
2-3. “Group” and “Block” definitions
The terms “Group” and “Block” used in this manual are defined as follows.
Group: Group is a group of air conditioning units and controllers and is the smallest unit that the AE-200/AE-50
can control. The maximum number of units that each group can contain is 16.
Block: Each block consists of one or more groups. Multiple groups of units in a given block can be monitored or
operated collectively.

5
WT07190X01
2-4. Main and Sub system controllers (M-NET)
Each group can be controlled by a Main system controller or a Sub system controller.
AE-200/AE-50 is exclusively for use as a Main system controller and cannot be used as a Sub system controller.
Main system controller
Main system controller refers to a system controller that controls all other system controllers including the units
they control. If a given system has only one system controller, that controller becomes a Main system controller.
Group settings and interlock settings can be made only from a Main system controller.
Sub system controller
Sub system controller refers to a system controller that is controlled by a Main system controller.
The system cannot be configured as shown in the examples below.
●Groups that are not under the control of a Main system controller cannot be controlled from a Sub system controller.
●Each group cannot be placed under the control of two or more Main system controllers.
●Sub system controllers cannot be placed under the control of two or more Main system controllers.
