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 leak ag e, ele ct r ic 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 aro un d 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 environmental pollution.

1-2. Precautions for relocating o r 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 so aked in water with mild detergent, and then wipe off with a dry cloth.

This appliance is not intended f or 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.

(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 set in the same 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.

[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 way as 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 the equivalent 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 the back of the unit, you will find the power jumper (CN21) of the AE-200/AE-50 in the place

indicated in the figure below.

○ If you remove the service cover from the front of the unit, you will find the power jumper (CN21) of the EW-50 in the place indicated in

the figure below.

[3] Restrictions and Notes on AC Power Supply Wiring

(1) Notes

1. Perform electrical work in accordance with the instructions in the installation manual.

2. To prevent electrical noise from the power supply wiring affecting the wiring for transmission (control), lay the power supply wiring

at least 5 cm (2 in) apart if laying the wiring in parallel.

(Do not insert them in the same conduit.)

3. Be sure to connect the ground wire for protection.

4. Select electrical wiring that meets the requirements in the following table.

Recommended power cable type

VCT, VVF, VVR, or its equivalent

Power cable size 0.75 to 2.00 mm2 (ø1.0 to ø1.6 mm)

[4] Restrictions and Notes on Transmission Wiring

(1) Notes

1. Perform electrical work in accordance with the instructions in the installation manual.

2. To prevent the wiring for transmission (control) from being affected by electrical noise from the power supply wiring, lay the wiring

for transmission (control) at least 5 cm (2 in) apart from the power supply wiring.

(Do not insert them in the same conduit.)

3. Never connect a 100 V or 200 V power supply to the terminal block for the transmission wiring. In the event that a power supply

is connected, the electrical components will burn out.

4. Use a 2-core shielded cable for the transmission wiring. Never use the same cable with multiple cores for wiring multiple systems

because the transmission signals will become unable to be sent and received normally, resulting in erroneous operation.

(2) M-NET transmission line

The type and tolerance of wiring differ depending on the system configuration. Furthermore, if the transmission line is long and there is a noise source within the vicinity of a unit, move the noise source away from the unit to prevent noise interference.

[III System restrictions and notes]

The following shows an example of a wiring diagram for the M-NET transmission line of CITY MULTI.

The example in the figure below shows the cable length limit of centralized control M-NET transmission line and indoor-outdoor M-NET transmission line for each system.

1. Farthest distance for M-NET transmission line (limited by attenuation of the signal waveform) ・ Make the distance between the transmission source and transmission destination of signals no more than 500 m (1640 ft).

If this maximum distance is exceeded, communication will become impossible due to the attenuation of the waveform. a+c+d ≤ 500 m (1640 ft), a+c+e ≤ 500 m (1640 ft), a+b+f ≤ 500 m (1640 ft), c+d+b+f ≤ 500 m (1640 ft), c+e+b+f ≤ 500 m (1640 ft)

2. Maximum power supply distance for M-NET transmission line (limited by voltage drop)

(1) Maximum total length of power feed for the centralized control transmission lines

・ Make the distance between the supply source and supply destination of power no more than 200 m (656 ft).

If this maximum distance is exceeded, communication will become impossible due to the voltage drop. a+c+d ≤ 200 m (656 ft), a+c+e ≤ 200 m (656 ft), a+b+f ≤ 200 m (656 ft)

* If a system remote controller, etc. is connected to the transmission line for centralized control, a power supply unit (PAC-SC 51KUA) is required. * There are cases where the supply source and supply destination of M-NET power differ depending on the setting of the M-NET supply connector.

(2) Maximum total length of power feed for the indoor-outdoor transmission lines

・ Make the distance from an outdoor unit to the supply destination no more than 200 m (656 ft).

c+d ≤ 200 m (656 ft), c+e ≤ 200 m (656 ft)

*1 The wiring length of the M-NET remote controller must be 10 m (32 ft) or less. If 10 m (32 ft) is exceeded, the portion that

exceeds 10 m (32 ft) must be included in the calculations for the maximum total wiring length of the M-NET transmission line (500 m (1640 ft)) and the maximum total power supply distance (200 m (656 ft)).

[6] Restrictions and notes on network wiring

NOTE: When connecting the AE-200/AE-50/EW-50 to t he Internet, be sure to use a VPN router or other security device to prevent unauthorized access.

(1) About LAN

We recommend using 100BASE-TX for the LAN. Also, with regard to the category of LAN cables, use category 5 or better for reasons such as availability and connectivity with optical cables (100BASE-FX). The main cable type is shown in the following table.

LAN standard Cable specification

Maximum wiring length

Communication speed

100BASE-TX

Twisted pair cable (T)

100 m (328 ft)

100 Mbps

(2) About HUB

Use a switching HUB for the HUB.

(3) LAN cable length

The maximum cable length for 100BASE-TX when connecting to the A E-200/AE-50/EW50 is 100 m (328 ft). Therefore, if the LAN cable length exceeds 100 m (328 ft), you can increase the distance between the PC for state monitoring and operation and the AE-200/AE-50/EW-50 by connecting via a switching HUB or other device.

NOTE: For details on the switching HUB, refer the instruction manual supplied with the switching HUB.

There is no limit on the number of switching HUB connections, but if the load on the network becomes extremely high, delays will occur and connecting normally with the network may not be possible. The recommended number of devices, including a HUB, gateway, router, or layer 3 switch, to connect between the AE-200/AE-50/EW-50 is four or less. (The transmission delay time must be 4 seconds or less round trip. If the transmission delay time needs to be checked because, for example, five or more devices are connected, refer to "V [5] 2. About the check method using ping.") If a LAN communication error code appears, check the error as described in "V [5] LAN communication error check procedure."

NOTE:

○ Use commercially available LAN cables.

[III System restrictions and notes]

[9] Other points to note

(1) About using General equipment

・ There may be cases when the general equipment cannot be monitored or operated due to, for example, a disconnection of the

wiring between the general equipment or a failure of the DIDO controller or PLC. In such a case, Mitsubishi Electric will not be held liable in the event of any damages. We recommend providing a circuit that enables emergency remedial operation, etc. to be performed when a failure occurs.

・ With the Ver.1 series of General Control PLC Software, the license number does not need to be registered to the

AE-200/AE-50/EW-50.

・ With the Ver.2 series of General Control PLC Software, General Control PLC Software License is not required to operate and

monitor general equipment and use the schedule functions, but TG-2000A is required. To use interlock control, General Control PLC Software License is required for each AE-200/AE-50/EW-50. General Control PLC Software License is required even for interlock control within the PLC.

・ A license number does not need to be registered to, for example, operate general equipment with a DIDO controller.

(2) About USB memory devices

● Select a USB memory device that meets the following conditions and verify operation several times before use. * Reading and writing with a memory device for which operation has not been verified may cause an unexpected operation.

Therefore, verify operation of the memory device (during trial operation) before use. Do not use a USB memory device for which a data writing error has occurred.

1. USB standard: Supports USB 2.0.

2. Formatted with FAT32 or FAT (FAT16)

3. Security function is not provided or not required to be set.

(Depending on the security function, there may also be some USB devices for which use is possible.) In cases such as when data writing can still not be performed normally when a USB memory device has been replaced with another one after a data error occurs, restart the AE-200/AE-50/EW-50 (turn the power off and then back on) and then perform the check again with a USB memory device other than the one with which the error first occurred.

● Do not remove and insert a USB memory device during writing to a USB memory device. A USB memory device may not be recognized if it is removed and inserted within a short period of time. If that happens, the unit needs to be restarted (turn the power off and then back on).

controller or PLC, the electricity meter to be monitored by the AE-200/AE-50/EW-50 must be one only, and it can be set for each AE-200/AE-50/EW-50.

Peak cut control cannot be used with air-conditioning units to be controlled by one AE-200/AE-50/EW-50 in a system with two or more electricity meters connected. Furthermore, use version 1.01 or later of the Electric Amount Count Software when using a PLC.

・ Peak cut control using a peak cut control device (peak cut level contact input method)

This method directly inputs a peak cut level signal to the AE-200/AE-50/EW-50 via an external input adapter (PAC-YG10HA). A PLC is not required for this method. The peak cut level monitoring and control commands can be issued from up to three AE-200/AE-50/EW-50 in addition to the connected AE-200/AE-50/EW-50.

・ Peak cut control using a peak cut control device (PLC method)

The PLC method sends a peak cut level signal from the demand controller to the AE-200/AE-50/EW-50 via a PLC. Furthermore, PLC software (PAC-YG41/42/43/91/92/93ATM) is required. Up to 10 AE-200/AE-50/EW-50 units can be set. If the number of AE-200/AE-50/EW-50 exceeds 10, install multiple PLC.

・ For peak cut control (other system method), up to 10 AE-200/AE-50/EW-50 units can be set. ・ Using a PI controller enables peak cut control from up to three AE-200/AE-50/EW-50 in addition to the

connected AE-200/AE-50/EW-50.

○ About apportioned electricity billing ・ The apportioned electricity billing function of the AE-200 and the apportioned electricity billing function of

the TG-2000A cannot be used at the same time. (Electricity apportioning will no longer be able to be

performed correctly.)

[3] Troubleshooting and solutions depending on the equipment

1. How to determine the caus e and res olve tr ouble based on the de tected e rror di spla y of the AE-200/AE-50/EW-50

The following shows the details, causes, and solutions for the error codes of errors detected at the detection source by the AE-200/AE-50/EW-50. First confirm that there is no mistake for each setting. *

The detection address displayed on the error monitor and in the error history is the address of the controller that detected the error.

Error code

Description and method of

detection

Cause Check procedure and remedy

0092

Version combination error

Error detected when the versions of the AE-200/AE-50/EW-50 are not a compatible combination for the apportioned electricity billing function.

1) The apportioned electricity billing

function of the AE-200 has been enabled but the AE-50/EW-50 is a version that is not supported (version earlier than 7.23) by the apportioned electricity billing function.

The apportioned electricity billing function of

the AE-200 does not operate while this error code is displayed. Update the AE-50/EW-50 to Ver.7.23 or later. Note: T he equipment recovers from the error

and then data collection resumes after

a maximum of 30 minutes elapse. For how to update the software, refer to "VIII [1] AE-200/AE-50/EW-50 update

procedure."

0093

System configuration

change warning

Error detected when the apportioned data is not restored when the AE-200/AE-50/EW-50 is replaced while the apportioned electricity billing function of the AE-200 is enabled.

1) The AE-200 and AE-50/EW-50 back

up each other’s data with the apportioned electricity billing function of the AE-200, but the backup data no longer matches after the AE-200/AE-50/EW-50 was replaced.

To prevent a loss of backup data, the

apportioned electricity billing function of the AE-200 does not operate while this error code is displayed. Perform an apportioned data restore for the new AE-200/AE-50/EW-50. Note: The equipment recovers from the error

and then data collection resumes after

a maximum of 30 minutes elapse. For how to restore apportioned data, refer to AE-200 Instruction Book (Apportioned

Electricity Billing Function).

0094

“Charge” license not

registered Error detected when a license is not registered to any of the AE-200/AE-50/EW-50 while the apportioned electricity billing function is enabled for an AE-200 without an apportioned electricity billing function

license.

1) With the apportioned electricity billing

function of the AE-200, the “Charge” license needs to be registered to all the AE-50/EW-50 under the control of the AE-200, but there is equipment to which it is not registered.

The apportioned electricity billing function of

the AE-200 does not operate while this error code is displayed. Register the “Charge” license to all the AE-50/EW-50 under the control of the AE-200.

0095

Warning - possibility of

damaged metering device

Error detected when the state of the measurement value of the meter not counting up continues for at least three days even though the operation amount of the air-conditioning units is being counted up while the apportioned electricity billing function of the AE-200 is enabled.

1) There is a wiring connection failure

between the electricity meter and PI controller. (When a PI controller is used)

2) There is a wiring connection failure between the electricity meter and the built-in PI of the AE-50/EW-50. (When meter pulse input (PI) of the AE-50/EW-50 is used)

3) There is an error with communication between the PI controller and AE-50/EW-50.

4) An electricity meter with pulse output of 10 kWh/pulse or higher is being used.

5) The carried-over data was not cleared after the time period of the unit price was deleted.

Causes 1 to 3) Check the wiring connections

to ensure there is no connection mistake or broken/disconnected wire.

Cause 4) If an electricity meter with a large

pulse output such as 10 kWh/pulse is used, three days or longer may be required to add one pulse depending on the operating conditions of the air-conditioning units. If changing the pulse output of the electricity meter is possible, change it to a value such as 1 kWh/pulse.

Cause 5) Perform the carried-over data

clearing process for the deleted unit price. For how to clear the carried-over data, refer to AE-200 Instruction Book (Apportioned Electricity Billing Function).

Note: The equipment recovers from the error

and then data collection resumes after

a maximum of 30 minutes elapse.

If the LAN cable is not connected or the IP address setting is incorrect, the reply is as follows.

Request timed out.

If the subnet mask, gateway, or other network setting is incorrect, the reply is as follows.

Reply from 192.168.1.250: Destination host unreachable.

The LAN cable connector is disconnected or the connection is incorrect.

Insert the connector of the LAN cable properly into the LAN port at the back of the AE-200/AE-50/EW-50. Furthermore, old types of HUBs have two port types, one for a terminal connection and one for a HUB connection, so check whether or not the LAN cables of the AE-200/AE-50/EW-50 and PC for the browser are

connected to ports for terminal connections.

The IP address and subnet mask settings are incorrect.

Unless other specified, set the IP address as follows.

AE-200: 192.168.1.1 to 192.168.1.40 AE-50: 192.168.1.211 to 192.168.1.249

Set the subnet mask to 255.255.255.0.

The gateway address setting is incorrect.

If a router is connected to the network, the gateway address needs to be set on the AE-200/AE-50/EW-50. Set the IP address of the router to which the AE-200/AE-50/EW-50 will be

connected as the gateway address.

LAN communication equipment (HUB or router) has failed. LAN cable disconnected or contact failure.

If a connection error reply is returned for the ping command even after checking the various settings above, the cause is probably a failure of the LAN communication equipment (HUB or router) or a defect of the LAN cable itself.

Replace the HUB or other communication equipment or the LAN cable

and then perform a connection check.

Check the waveform of the transmission line with an oscilloscope. The following conditions must be met.

1) There must be no small waveform (noise) in the transmission signal. (Small noise of approximately 1 V caused by the operation of a DC-DC converter or inverter may be noticeable but such noise should not be a problem when the unit and transmission line shield are grounded.)

2) The voltage level of each portion of the transmission signal must be as follows.

(3) Check and solution

If noise is confirmed in the waveform or any of the errors of the error codes in (1) occur, perform the following checks.

Error description

Action

Wiring method check

1. Are the transmission line and power cable

(100—240VAC) routed together?

Lay the power cable as far away as possible. When laying the

cables over a long distance, provide a space of at least 5 cm between them.

In particular, do not insert them in the same conduit.

2. Is the transmission line bundled together

with the transmission line of another system?

Lay the transmission line so that it is separate from other

transmission lines. When it is bundled with another transmission line, there is the risk of

erroneous operation.

3. Is the specified cable being used for the

transmission line?

Use the specified transmission line.

Transmission line type CVVS/CPEVS/MVVS shielded cable

(for M-NET remote controller)

Transmission line diameter At least 1.25 mm

(Remote controller wire: 0.5 to 1.25 mm2)

4. When the transmission line is

daisy-chained on the indoor unit terminals, is the shield daisy-chained too?

The two wires of the transmission line are daisy-chained. The shield

must also be daisy-chained in the same way as the transmission lines. If the shield is not daisy-chained, its effect on reducing noise will be

small.

5. Is the transmission line grounded with the earth?

Prevent parts from being grounded with the earth.

6. Is the transmission line connected to the junction terminals properly?

If bare wires are twisted together, connect the wires properly by, for example, crimping them together.

Grounding method check

1. When the transmission line is

daisy-chained, is the shield daisy-chained too?

Ground one point of the shield at a unit that supplies power.

If no grounding is provided, the noise on the transmission line cannot escape so there is the risk that the transmission signal will be

transformed.

2. Check the treatment method of the shield

of the transmission line (for centralized control).

The transmission line for centralized control is less susceptible to

noise interference if it is grounded from one outdoor unit in the case of group operation between units with different refrigerant or from the system controller in the case of using a system controller. However, the environment against noise varies depending on the distance of the transmission lines, the number of the connected units, the type of the controllers to be connected, and the environment of the installation site, so check that the transmission line work for centralized control has been performed as follows. a) When not grounded

・ Group operation between units with different refrigerant

Grounded at one outdoor unit (power supply unit)

・ Using system controller

Grounded at a power supply unit (including a system controller with a built-in power supply)

b) When an error occurs even though grounded at one point

Ground the shield at all outdoor units and power supply units (including system controllers with a built in power supply)

If the peak value is low, if a 66xx error occurs, or if the remote controller remains in the initial screen display state

Error description

Action

1. The distance to the farthest end of transmission line exceeds 200 m (656 ft).

Check that the distance from the outdoor unit or power supply unit to

the indoor unit and to the remote controller at the farthest end is 200

m (656 ft) or less.

2. The types of transmission lines differ.

Use the specified transmission line.

Transmission line type: CVVS/CPEVS/MVVS shielded cable Transmission line diameter: At least 1.25 mm2 (remote controller

wire: 0.5 to 1.25 mm2)

3. Outdoor unit board failure

Replace the outdoor unit control board or transmission power supply board.

4. Indoor unit or remote controller failure

Replace the indoor unit control board or remote controller.

5. The MA remote controller is connected to the

M-NET transmission line.

Connect the MA remote controller to the MA remote controller

terminal block (TB15) on the indoor unit control board.

NOTE:

For details on the restrictions on wiring length, refer to "III [4] Restrictions and notes on transmission wiring."

[How to check when a LAN communication error occurs in a system connected via a router (how to isolate the cause)]

When LAN communication is not performed properly (pinging is not successful*1) in a system connected using a router, you can isolate the cause as follows.

*1 Check whether pinging the AE-200/AE-50/EW-50 from a PC is successful when there is a connection via a router in advance.

Step

Method

Supplement

1 Prepare a PC that is connected to the same network. Use a PC in the

same network with no connection via the router.

If there is no PC connected to the network, identify an IP address that it is alright to use and then connect a PC with that IP address

set.

2 Ping the AE-200/AE-50/EW-50 or other target equipment from the PC.

Run the following in the command prompt. ping␣－t␣[IP address of target equipment]

[Example] ping -t 192.168.1.1

⇒ When pinging is successful:

There may be a problem with the gateway setting of the target equipment or the router settings. Consult with the equipment administrator. For the gateway address setting, check "8-2-6. Network settings" in AE-200/AE-50 Instruction Book. For the router settings, check the Instruction Book of the router.

⇒ When pinging failed:

There may be a problem with the IP address setting of the target equipment. Check the setting. If the problem still cannot be resolved, there is likely to be a problem

with the network of the router. Consult with the system administrator.

* For the operating procedure, refer to

[Ping check method] on the previous page.

[How to check that an IP address is not duplicated]

If it is not possible to check the IP addresses of all equipment, there is the following method using a PC to check with the command prompt. (Supplement) If all connected equipment in a system in an existing network cannot be checked, you can compare the MAC addresses of the equipment of only the air conditioning control system to check if an IP address is duplicated.

Symptom

Cause

Check procedure and remedy

The peak cut control status does not match on the actual equipment and the AE-200/AE-50/EW-50 (Web browser) or TG-2000A screen.

(Display timing offset)

There is a difference in the monitor timing.

- (Normal) → An offset occurs due to the monitor timing.

It is hot as cooling has no effect due to peak cut.

1) Control is always at the highest

level because the set peak cut

power value is low.

Check how low the peak cut level is set (*1) and if it is low, do the following.

Cause 1) Consider whether the peak cut level can be changed. *1 The level can be checked in the [Energy Mgmt] - [Peakcut]

screen on the AE-200 LCD.

Peak cut control is not being performed normally.

1) The license is not registered to the AE-200/AE-50/EW-50.

2) The power of the AE-200/AE-50/EW-50, PI controller, PLC is shut down.

3) The M-NET transmission line or a LAN cable is broken or disconnected.

4) The operation block is not set.

5) The control settings of peak cut control are not set or the settings are incorrect.

6) There is a pulse setting mistake (in the case of a PI controller). The pulse unit is set on the PI controller even though it is connected with the AE-200/AE-50/EW-50 or

TG-2000A.

Check causes 1) to 7). Take the measure corresponding to the cause.

Is it possible to set the set temperature

range limit on a Mr. Slim model from the AE-200/AE-50/EW-50 via an M-NET adapter?

The set temperature range limit cannot be set via an M-NET adapter.

For the settings of an MA remote controller, set them on the actual MA remote controller. For the settings of a ME remote controller, there is no connection via an M-NET

adapter.

Are the USB memory devices that can

be used only those specified?

For AE-200/AE-50, select a USB memory device that meets the following conditions

and verify operation several times before use.

* Reading and writing with a memory device for which operation has not been

verified may cause an unexpected operation. Therefore, verify operation of the memory device (during trial operation) before use. Do not use a USB memory device for which a data writing error has occurred.

1. USB standard: Must be USB 2.0 compliant

2. Format: Must be formatted in FAT32 or FAT (FAT16).

3. Must have no security function or be able to be used without the security function. (Depending on the security function, there may also be some USB devices for which use is possible.)

In cases such as when data writing can still not be performed normally when a USB memory device has been replaced with another one after a data error occurs, restart the AE-200/AE-50 (turn the power off and then back on) and then perform the check

again with a USB memory device other than the one with which the error first occurred.

Can the set temperature range limit be

set on the system remote controller

from the AE-200/AE-50/EW-50?

No, it cannot be set on the system remote controller.

It can be set only on local remote controllers (ME and MA).

Question

Answer

What is the concept of peak cut control?

The concept of peak cut control is to control the operation of the air-conditioning units

to save energy by switching to each group in the operation block in order. (There are also some functions that cannot be implemented depending on the target air-conditioning units.)

・ Change the set temperature ・ Switch to fan operation (or forced thermo-OFF operation) ・ Stop ・ Outdoor unit capacity save

Peak cut control (level 0) always performs control regardless of the electric energy consumption. Whereas peak cut control (levels 1 to 4) always monitors electric energy consumption and performs control when the predicted value of average electric energy in a 30-minute period has exceeded a preset level.

Does control always begin from the same

group in peak cut control rotation?

Peak cut control is implemented in both the 30-minute units of 0 to 29 minutes and

30 to 59 minutes so control does not always begin from the same indoor unit group and same outdoor unit (address that is lowest). However, since the electric energy reduction request from the power company becomes a peak cut power level signal of a 30-minute unit and 60-minute unit, control always begins from the same indoor unit group and same outdoor unit (address that is lowest).

Is peak cut also possible for another

company's air-conditioning units, lighting, and other equipment?

No, it is not.

The target for peak cut control performed by a AE-200/AE-50/EW-50 system is only Mitsubishi Electric's air-conditioning units (products incorporating M-NET).

Is peak cut control possible for a DIDO controller?

A DIDO controller is not supported for peak cut control.

What is the control unit for peak cut control?

The control of indoor units is performed for the unit of a group in the operation block. The control of outdoor units is performed for the unit of an outdoor unit.

If the capacity save amount of an outdoor

unit is set to 80%, will electric energy consumption be reduced to 80%?

The 80% figure for saving is with regard to the maximum frequency of the

compressor. This does not mean a reduction of the electric energy amount to 80%.

Is capacity save of outdoor units

supported for all room air-conditioners, A control Mr. Slim, and MULTI air conditioners?

It is not supported for room air conditioners.

Support is possible for the inverter outdoor unit of a MULTI air conditioner. For the inverter outdoor unit of a Mr. Slim, support for outdoor unit capacity save can be provided by using peak cut. It is not supported for PUMY.

Is it possible to implement only peak cut

control even though a PI controller is not

connected?

If a license is registered, it is possible to use only level 0.

Is it possible to connect an electricity

meter to the PI controller and then perform control according to the peak cut level within the range of multiple

AE-200/AE-50/EW-50 units?

Yes, it is.

Peak cut control using a PI controller can control within the range or up to four AE-200/AE-50/EW-50 units.

Can the set temperature be changed with

the ME remote controller or MA remote controller during set temperature ±2°C (±4°F) control with peak cut control?

Yes, the set temperature can be changed.

However, if the set temperature is changed during peak cut control, ±2°C (±4°F) control is performed again for the new temperature. Also, the set temperature will be the new set temperature after peak cut ends. Example: 1. Peak cut control (+2°C (±4°F)) starts with cooling at 26°C (79°F).

⇒ Set temperature is 28°C (82°F).

2. Changed to 24°C (75°F) with the remote controller.

⇒ Set temperature is 26°C (79°F).

3. Peak cut ends. ⇒ Set temperature is 24°C (75°F).

Why is capacity save with PUMY using

peak cut control not possible?

This is because even though PUMY is an inverter model, the unit does not support

the capacity save settings.

Is it possible to connect a demand

controller to an external input of the AE-200 and then perform peak cut control for an AE-50 system?

Yes, it is. Yes. Set the settings as described in the following procedure.

1. Select [Other AE] in [System Settings] of [Function1] - [Peak Cut Settings] on the AE-50 Web Browser for Initial Settings.

2. The IP address input field appears. Enter the IP address of the AE-200 with the external input connected.

Note: For the AE-200/AE-50 with [Other AE] selected, a delay of up to 1 minute

occurs when starting peak cut control.

Question

Answer

1 Is the controller to use different for

managing 50 units or less and 200 units or less?

50 units or less: AE-200 or EW-50 From 51 to 200 units: AE-200 (with M-NET connection) + AE-50/EW-50 (1 to 3 units) From 51 to 200 units: AE-200 (without M-NET connection) + AE-50/EW-50 (2 to 4 units) In the case of 51 to 200 units, it is necessary to add a HUB, change the wiring connections, etc.

2 Can the TG-2000A be connected with a

mixture of AE-200/AE-50/EW-50 and G-150AD or G(B)-50?

Yes, it can. The TG-2000A that supports AE-200/AE-50/EW-50 is Ver.6.60 or later. When the TG-2000A is connected with a mixture of AE-200/AE-50/EW-50, the maximum number of indoor units that can be targets for operation and monitoring is 2,000.

3 If the power of the

AE-200/AE-50/EW-50 is cut because of, for example, a power failure, how long will the backup data be retained?

The current time is backed up for about one week and is then reset (2014/04/01). The settings are retained but there are data retention periods. For example, the period is 62 days in the case of billing data and 24 months in the case of energy usage status data. When a retention period elapses, the data is overwritten.
