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.

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.

WT07919X04

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.

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.

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.

2-1. Introduction

The AE-200/AE-50/EW-50 BACnet® function can be used when connecting AE-200/AE-50/EW-50 to the open network BACnet® that is used for the building management system. The air conditioning units connected to AE-200/AE-50/EW-50 can be monitored and operated not only from the existing web browser or the AE-200/AE-50’s LCD, but also from the building management system using the BACnet® communication protocol.

Note

The explanation of the BACnet® function in this manual is based on the specification of AE-200/AE-50/ EW-50 software version 7.50.

2-2. License

2-4. Restrictions and cautions

Restrictions and cautions for AE-200/AE-50/EW-50 BACnet® functions are as follows.

(1) Action to take when an error occurs

Immediately carry out repairs to the problem area when an error related to air conditioning units is detected on the building management system.

(2) Functions

Due to continuing improvement, specifications are subject to change without notice.

(3) Request interval

When sending “ReadProperty” or “WriteProperty” from the building management system to the AE-200/AE-50/EW-50, set the interval to 200 (ms/property) or above.

When sending 10 properties using “ReadPropertyMultiple”, wait for at least 2000 ms (= 200 ms × 10 properties) before sending another request to the AE-200/AE-50/EW-50.

3. Usage (System configurations)

3-1. Sample system configurations

(1) When controlling 50 or fewer units of equipment and not using an apportioned electricity

billing function

*1 Use a switching HUB to connect to LAN1 and LAN2 (BACnet®). Do not connect LAN1 and LAN2 (BACnet®) to the same HUB. *2 A PC (hereafter referred to as Setting PC) is required to make settings for the AE-200/EW-50 BACnet

functions. After making settings, disconnect the Setting PC as well as LAN cables and HUBs used to connect to the Setting PC from the AE-200/EW-50. Refer to section 7 “Checking installation operations and performing trial run” for details.

(2) When controlling more than 50 units of equipment *3 and not using an apportioned

electricity billing function

functions. After making settings, disconnect the Setting PC from the AE-200/AE-50/EW-50. Refer to section 7 “Checking installation operations and performing trial run” for details.

*3 Up to 50 units of equipment can be connected to and controlled by each AE-200/AE-50/EW-50. If performing centralized control with an

AE-200, up to 3 AE-50/EW-50 can be connected to a single AE-200 (if not using AE-200 M-NET, up to 4 can be connected).

*4 If performing centralized control with an AE-200, because time synchronization from the building management system comes through

the AE-200, then for systems including those that do not have BACnet

control functions, configure so that AE-200 is connected to the

BACnet®, by connecting devices to control with BACnet® to the AE-200.

(3) When using an apportioned electricity billing function

functions. After making settings, disconnect the Setting PC from the AE-50/EW-50. Refer to section 7 “Checking installation operations and performing trial run” for details.

*3 If using the apportioned electricity billing function, we recommend that instead of using the AE-50/EW-50 built-in Pulse Input (PI), the PI

controller be used for measurement of electric energy. (If AE-50/EW-50 built-in Pulse Input (PI) is used, pulse input will not be possible when the AE-50/EW-50 is stopped, during power outages or during software updates. This could result in discrepancies between the measurements and the actual electric energy consumed.) When using the AE-50/EW-50 built-in Pulse Input (PI), approve the above-mentioned restrictions for the customer and then use.

*4 Up to 50 units of equipment can be connected to and controlled by each AE-50/EW-50. Up to 4 AE-50/EW-50 controllers can be

connected to each AE-200 for billing function.

*5 To use an apportioned electricity billing function and perform date and time synchronization from the building management system, set

the “Time Master/Sub” setting to “Sub” on the AE-200 for billing function and synchronize the time from AE-50/EW-50 connected to BACnet

. The “Time Master/Sub” setting can be made on the Initial Setting Tool, Web Browser for Initial Settings, or AE-200/AE-50’s

LCD. (Refer to the AE-200/AE-50/EW-50 Instruction Book (Initial Settings) for settings methods.)

*6 If using the apportioned electricity billing function, connection of M-NET and Pulse Input (PI) to the AE-200 for billing function is

prohibited. Accordingly, the AE-200 for billing functions does not have any BACnet

control devices, and BACnet® connection is not

necessary. As a result, BACnet® settings and "BACnet connection" license are not required for the AE-200 for billing function.

*7 If using the apportioned electricity billing function, connection of LAN1 for transfer of power apportioning information is required.
