*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/AE-50/EW-50 BACnet

®

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

*4

*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-50/EW-50 BACnet

®

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.

5-5. Apportioned electricity billing function

The AE-200/AE-50/EW-50 apportioned electricity billing function calculates the “electric energy for the
electricity meter” and the “apportioned electric energy for the electricity meter per group/interlocked unit” or the
“apportionment parameters for apportioning the electric energy per group/interlocked unit,” and stores this in the
accumulator. Additionally, the accumulator is stored in “Log_Buffer” of the trend log.
The cumulative value and trend log data can be read by BACnet® communication.
BACnet® communications cannot read billing information.
When using the apportioned electricity billing function, a “Charge” license is required for each
AE-200/AE-50/EW-50. Refer to the AE-200/AE-50/EW-50 Instruction Book (Apportioned Electricity Billing
Function) for details on the apportioned electricity billing function.
When using the apportioned electricity billing function, refer to (3) “When using an apportioned electricity billing
function” in section 3-1 “Sample system configurations” for system configuration.

5-5-1. Apportioned electricity billing function specifications

The apportioned electricity billing function in the BACnet® function is configured of an accumulator object which
stores the electric energy and other cumulative value/apportioned results cumulative value and the trend log
object which reads the accumulator for each fixed time and accumulates the value. When using the apportioned
electricity billing function, a “Charge” license is required.

Note

An interlocked unit is an OA Processing Unit (FU attribute) linked to an indoor unit, and covers those
affiliated OA Processing Units that can be registered in the energy management block settings of the Initial
Setting Tool.
This does not refer to an OA Processing Unit (IC attribute) that is not linked to an indoor unit that can have
group settings performed through the centralized controller.

5-5-4. System restrictions for apportioned electricity billing function

• “Charge” license is required for each AE-200/AE-50/EW-50.

• Combinations of AE-200 and AE-50/EW-50 units are required.

• M-NET of AE-200 for billing function cannot be used.

• Built-in Pulse Input (PI) of AE-200 for billing function cannot be used.

• Electric energy measurement using a PI controller is recommended.

(If AE-50/EW-50 with 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.)

• Ensure that the same software versions are used on AE-200/AE-50/EW-50 units.

• The apportioned electricity billing function (AE-200 Apportion) and apportioned electricity billing function

(TG-2000A Apportion) cannot be used together.

• When the apportioned electricity billing function (AE-200 Apportion) is being used and you intend to use
the TG-2000A integration software, check that the TG-2000A version is 6.60 or later.

• An electricity meter is required for each AE-200 and for each AE-200 system comprising expansion
controller AE-50/EW-50. You cannot make settings (apportionment settings) that span multiple AE-200
systems.

29

WT07919X04

5-5-5. Notes on using the apportioned electricity billing function

• This function is our original electric energy apportionment system that apportions electric energy using
input from electricity meters with a pulse generator function. Rather than directly measuring the electric
energy consumed by each air conditioner, pulses are input based on the air conditioner usage by
determining the air conditioner operating status from the content of its communication with the indoor and
outdoor units.

To all users (user license agreement)

The information provided here constitutes an agreement between Mitsubishi Electric and the
customer.
If this “apportioned electricity billing function for the AE-200 air conditioning control system” is used,
this agreement assumes that the customer is using the aforementioned system having agreed to the
terms listed below.

• Mitsubishi Electric and its sales companies accept no liability whatsoever for any incidental,
consequential or special damages incurred by the customer, even where the sales company has
received notification of the potential for damages of that kind.
Nor is any liability accepted for any allegations regarding the rights of a third party.

Important

Any individual agreement between the building owner and a tenant regarding the use of this product
should incorporate the parties’ agreement to or accord with the fact that “charges for the use of air
conditioning will be collected in the form of apportioned totals based on the operating status of air
conditioners (including temporary measures to deal with faults)”.

• This is a system for estimating the operating electric energy consumed for air conditioning. As
such it cannot be used as a proof of transaction.
Also, amounts metered using electricity meters are also counted using pulse conversion and
cannot be used as a proof of transaction.

• This is not a system (or its equivalent) in which the operating electric energy consumed by each air
conditioner is directly measured at the location where the electricity is supplied.

• Because this is an apportionment method that uses the operating status of air conditioner indoor units,
even where the operating time for indoor units is the same, the amount of operating electric energy
consumed may differ depending on the model configuration and operating status of the outdoor units.
(The apportioned electric energy may be different when compared with a situation where an electricity
meter is assigned to each air conditioner.)

• Air conditioners still receive current even when stopped, and electric energy is apportioned to idle air
conditioners as standby electric energy.

• While the amounts of electric energy, water and gas consumed are obtained through pulse
conversion, factors such as performance and accuracy are dependent on the metering devices and
Mitsubishi Electric is in no way responsible for such factors.

• If electric power to the AE-200/AE-50/EW-50 and PI controller is interrupted due to a power outage but the
air conditioner is still running, electric energy cannot be apportioned correctly.

• Because the unit price digits for each tenant (energy management block) are rounded off in the charge
calculation process, the figures may differ from the total electric energy charges.

• Adjust the time in the following method as there are discrepancies in the results of apportionment
processing when there is a time lag.
When there is no connection to BACnet

®

or when time synchronization is not carried out from the building
management system, perform periodic time adjustment on the AE-200’s LCD. (Even if time is adjusted
with AE-50/EW-50, it is overwritten with the time of AE-200.)
To perform date and time synchronization from the building management system with connection to
BACnet®, set the “Time Master/Sub” setting to “Sub” on the AE-200 for billing function. 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.)

• Mitsubishi Electric accepts no liability for the incorrect apportionment of electric energy due to problems
such as power outages or equipment faults.

7. Checking installation operations and performing
trial run

For air conditioning system designs before initial settings, consult your dealer.

7-1. Flow of initial settings

In general, the initial settings are largely divided into 4 steps as follows.
By making initial settings along these 4 steps, the cause classification in case of trouble is clarified in each step
and the initial settings can be advanced efficiently.

Make the initial settings according to the following procedures.

Step-1 Initial settings for the air conditioning system

Make the system setting of AE-200/AE-50/EW-50 and unit setting of the air conditioning system, and register
the required licenses. This is also a step to make initial settings other than for the apportioned electricity
billing function and BACnet

®

functions.
(Refer to the AE-200/AE-50/EW-50 Instruction Book (Initial Setting) for making the system setting of
AE-200/AE-50/EW-50 and the unit setting of the air conditioning system, and registering the licenses.)

Step-2 Trial run of the air conditioning system

Check to see that the air conditioning unit and controller, etc. have the correct system configuration or to see
that the air conditioning unit is operating normally. (Refer to AE-200/AE-50/EW-50 Installation Manual for the
method of trial run.)

Initial settings for apportioned electricity billing function

Make initial settings for the apportioned electricity billing function.
(Refer to the AE-200/AE-50/EW-50 Instruction Book (Apportioned
Electricity Billing Function) for initial settings procedures for apportioned
electricity billing function.)

Step-3 Initial settings for the BACnet® related items

Using the BACnet

®

Setting Tool, make settings related to BACnet® of AE-200/AE-50/EW-50.

(For BACnet® related settings, refer to the AE-200/AE-50/EW-50 Instruction Book (BACnet® Setting Tool).)

Trial run of apportioned electricity billing function

Carry out a trial run of an apportioned electricity billing function.
(Refer to the AE-200/AE-50/EW-50 Instruction Book (Apportioned
Electricity Billing Function) and the AE-200/AE-50/EW-50 Instruction
Book (BACnet

®

Apportioned Electricity Billing Function Trial Run) for

trial run procedures.)

Step-4 Trial run of BACnet® function

Check that the operational status and alarms for air conditioning units are being displayed and reported
correctly in the BACnet

®

Trial Run Tool; that the air conditioning units are operating in accordance with

operation or settings from the BACnet® Trial Run Tool.

Make the initial settings related to BACnet® using the BACnet® Setting Tool.

(1) Data setting

LAN2 (BACnet®) settings and BACnet® related settings are made using the BACnet® Setting Tool which
has been installed on the Setting PC. Because the BACnet® Setting Tool can only configure single
AE-200/AE-50/EW-50 at one time, even when the system is configured with multiple AE-200/AE-50/EW-50
units, it is necessary to configure each AE-200/AE-50/EW-50 unit.
The setting items are as follows. (Refer to the AE-200/AE-50/EW-50 Instruction Book (BACnet® Setting Tool)
for details for each of the items.)

7-7. When changing settings or reconfiguring AE-200/AE-50/EW-50

The procedures for changing settings or reconfiguring AE-200/AE-50/EW-50 using stored settings data are as
follows.

Important

When AE-200/AE-50/EW-50 is reconfigured, communication with the building management system is
temporarily cut off and the building management system may detect a communication error. Carry out
operations after receiving approval from the building manager beforehand.

(1) Connecting Setting PC

Before the Setting PC is connected to AE-200/AE-50/EW-50, remove the LAN cable of LAN2 of
AE-200/AE-50/EW-50 connected to BACnet®.
Connect the LAN 1 of AE-200/AE-50/EW-50 and the Setting PC using a LAN cable via a HUB.

(2) Data setting

Setting changes are made on the Setting PC or the setting data stored is read to reconfigure
AE-200/AE-50/EW-50.
Settings are performed for initial settings in the air conditioning system, the apportioned electricity billing
function settings (only when used) and the BACnet® related settings, in that order.
(For details on setting items and settings in each procedure, refer to section 7-3 “Step-1 Initial settings for
the air conditioning system”, AE-200/AE-50/EW-50 Instruction Book (Apportioned Electricity Billing Function),
section 7-5 “Step-3 Initial settings for the BACnet® related items”, and AE-200/AE-50/EW-50 Instruction Book
(BACnet® Setting Tool).)
Before configuring the BACnet® related items, it is required to set the BACnet® connection mode to
“OFFLINE” from the BACnet® Setting Tool.

(3) Air-conditioning system and apportioned electricity billing function trial run

Carry out a trial run for the air conditioning system and a trial run for the apportioned electricity billing
function. Refer to the respective unit Installation Manual for the method of carrying out a trial run of the air
conditioning system and the AE-200/AE-50/EW-50 Instruction Book (Apportioned Electricity Billing Function)
for the method of carrying out a trial run of the apportioned electricity billing function.

(4) ONLINE setting

A setting is made to “ONLINE” from the BACnet® Setting Tool. AE-200/AE-50/EW-50 restarts automatically.
(approximately 10 minutes for maximum time required)
When AE-200/AE-50/EW-50 restarts, a group device with no remote controller may stop.
