Safety precautions
Thoroughly read this instruction book before use to ensure safety.
Before using the BAC-HD150, read the Safety Precautions section carefully to ensure proper operation.
These safety precautions must be observed by anyone who operates the BAC-HD150.
Keep the Instruction Book and Installation Manual for future reference. Make sure both manuals are passed on to any
future air condition system users.
WARNING This symbol indicates that failure to follow the instructions exactly as stated poses the risk
of serious injury of death.
CAUTION This symbol indicates that failure to follow the instructions exactly as stated poses the risk
of injury or damage to the BAC-HD150.
WARNING
CAUTION
The unit must be installed by a dealer or technical
representative.
Improper installation by an unqualified person may result
in electric shock and fire.
Install in a location that is strong enough to
withstand the weight of the unit.
A weak installation area may cause the unit to fall down,
resulting in a personal injury.
Only use specified cables. Securely connect each
cable so that the weight of the cable is not applied to
the connectors.
Loose or improper connections may result in heat
generation or fire.
If any abnormality is noticed (e.g., burning smell), stop
the operation, turn off the power supply, and contact
your dealer or technical representative immediately.
Continuing the operation may result in damage to the
BAC-HD150, electric shock, or fire.
Ask your dealer or an authorized technician to move
or reinstall the BAC-HD150.
Improper installation may result in an electric shock or
fire.
BAC-HD150 must be disposed of properly.
Contact your dealer for proper disposal procedures.
Do not attempt to modify or repair the BAC-HD150.
Modification or improper repair may result in electric
shock or fire. Consult your dealer when repairs are
necessary.
Stop the operation immediately and notify your
dealer if the BAC-HD150 does not operate, or when
any abnormality is noticed.
Continuing the operation may result in damage to the
BAC-HD150 or fire.
Do not install the BAC-HD150 where there is a risk of
leaking flammable gas.
If the leaked gas accumulates around the BAC-HD150, it
may ignite and cause an explosion.
Do not wash the BAC-HD150 with water.
Doing so may cause an electric shock or malfunction.
Do not use the BAC-HD150 for specialized
applications.
This product is designed exclusively for use with the
MITSUBISHI ELECTRIC building air conditioning control
system. The use of this product for other purposes may
result in malfunctions.
Do not spray insect sprays or sprays with flammable
propellants to the BAC-HD150.
To avoid the risk of fire or explosion, do not place
flammable sprays near the BAC-HD150 or spray them
directly on the BAC-HD150.
Do not apply mechanical shock to BAC-HD150.
Do not use the BAC-HD150 in an environment high in
oil, steam, or sulfuric gas.
These substances may have adverse effects on the
performance of the BAC-HD150 or damage its parts.
Operate the BAC-HD150 within the temperature range
specification.
The use of controller outside of its specification may
result in serious damage to the BAC-HD150. Be sure to
check the temperature range specification in the
Installation Manual.
Use a security device such as a VPN router when
connecting the BAC-HD150 to the Internet to prevent
unauthorized access.
If no security devices are installed, the operation settings
may be changed by an unauthorized person without the
knowledge of the user.

1.2 Restrictions/Cautions
Restrictions and Cautions for BAC-HD150 are as follows.
(1) Restrictions on the system configuration
(a) When BAC-HD150 is connected to M-NET
(b) When BAC-HD150 is connected to PAC-YG50ECA (Expansion Controller)
• Restrictions on the DB No.
Controllers (PAC-YG50ECA, AG-150A and BAC-HD150) with different DB No. cannot be connected to each other.
When DB No. on the controllers is different, update the software version of the controllers.
Refer to section 3-3 “System in which BAC-HD150 is connected to PAC-YG50ECA (Expansion Controller)” in the
BAC- HD150 Installation Manual for information about DB No.
(2) Connecting AG-150A
• When connecting BAC-HD150 to PAC-YG50ECA, connect AG-150A to set the M-NET address, group, and interlocked
operation with LOSSNAY for PAC-YG50ECA.
(3) Supports for errors
• It is recommended to recover the system immediately when errors related to air conditioning are displayed on the building
management system.
(4) Operation during power failure
• When BAC-HD150 needs to be operated during power failure, a power backup device such as UPS (Uninterruptible Power
Supply) is recommended to be installed.
(5) Functions
• Due to continuing improvement, specifications are subject to change without notice.
(6) Models in a group
• BAC-HD150 monitors and controls indoor units for each group (*1).
To group multiple indoor units, use the same models in a group.
*1 : Group has two types: a unit in a group or multiple units in a group.
(7) Request interval (from BMS* to BAC-HD150) *BMS=Building Management System
• When sending Read_Property or Write_Property from BMS to BAC-HD150, set the interval to 200 (ms/property) or above.
[Ex.1]

When sending 10 properties using Read_Property_Multiple, wait for at least 2000 ms (= 200 ms 10 properties) before
sending another request to BAC-HD150.
[Ex.2]
(8) Restrictions on setting temperatures (dual set points/single set point)
Two types of temperature setting modes are used by some indoor units.
[Dual set points] . . . .Different temperature settings can be set to Cooling and Heating modes, and the Setback
function is also supported.
[Single set point]. . . .The same temperature settings are used in both Cooling and Heating modes. (Does not support
the Setback function)
Restrictions on setting temperatures (dual set points/single set point) are as follows.
(a) Monitoring setting temperatures from BMS
When sending temperature setting commands from BMS, note that different objects are used to set the setting temperatures
for dual set point indoor unit groups and single set point indoor unit groups. Refer to section 3.5 “Temperature setting objects”
in this manual for details.
(b) When dual set point indoor units and single set point indoor units are included in the same group
All indoor units in the same group will operate as single set point indoor units. Use single set point temperature setting object
(AV_xxxx10).
(c) When the BMS does not support the dual set point function
Enable “Old Model Compatibility Mode” of the BAC-HD150 Setting Tool. All indoor unit groups will be treated as single set
point unit groups because the BAC-HD150 will act as a single set point device.
Refer to section 8.2 “System Settings” in BAC-HD150 Setting Tool Instruction Book for details.
(d) When using PAC-YG50ECA
Systems with connections to PAC-YG50ECA and BAC-HD150 do not support the dual set point function. When using PAC-
YG50ECA, enable “Old Model Compatibility Mode” and “Expansion Controller Settings” on the BAC-HD150 Setting Tool. All
indoor unit groups will be treated as single set point unit groups. Refer to section 8.2 “System Settings” in BAC-HD150
Setting Tool Instruction Book for details.
(e) When using system controllers that do not support the dual set point function
When using system controllers that do not support the dual set point function, enable “Old Model Compatibility Mode” on the
BAC-HD150 Setting Tool. All indoor unit groups will be treated as single set point unit groups.
Refer to section 8.2 “System Settings” in BAC-HD150 Setting Tool Instruction Book for details.
(9) When connecting a superior system controller
Register the superior system controller as a System Controller from the BAC-HD150 Setting Tool. Refer to section 8.3
“Group settings” in the BAC-HD150 Setting Tool Instruction Book.
Also, register BAC-HD150 as a System Controller to the superior system controller.
(10)Use of AHC
BAC-HD150 does not support AHC. AHC cannot be controlled from BAC-HD150.
