1. Safety precautions
Before using the controller, read the Safety Precautions section carefully to ensure proper operation.
These safety precautions must be observed by anyone who operates the centralized controller at all times.
Keep this Instruction Book and Installation Manual for future reference. Make sure both this Instruction Book and the
Installation Manual are given to the next user.
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 controller.
WARNING
CAUTION
Have the unit professionally installed.
Improper installation by an unqualified person may result in
a risk of electric shock or fire.
Make sure the controller is securely mounted so that it
will not fall.
Make sure that the controller is connected to a properly
rated power supply to avoid fire or damage to the
controller.
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
controller, electric shock, or fire.
Ask your dealer or an authorized technician to move
the controller.
Improper installation may result in electric shock or fire or
damage to the controller.
Controllers must be disposed of properly.
Contact your dealer for proper disposal procedures.
Do not attempt to modify or repair the controller.
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 an error code is displayed and the controller does
not operate, or when any abnormality is noticed.
Continuing the operation may result in damage to the
controller or fire.
Do not install the controller where there is a risk of
leakage of flammable gas.
If the leaked gas accumulates around the controller, it may
be ignited and result in an explosion.
Do not wet the controller.
Water may damage the controller and cause an electric
shock.
Do not use the controller for specialized applications.
This product is designed exclusively for use with the
MITSUBISHI ELECTRIC building air conditioning control
system. The use of this product with other air-conditioning
management systems or for other purposes may result in
malfunctions.
Do not spray insect sprays or sprays with flammable
propellants to the controller.
To avoid the risk of fire or explosion, do not place
flammable sprays near the controller or spray them directly
on the controller.
To reduce the risk or electric shock and malfunctions,
do not operate the touch panel with wet hands.
Do not use the controller in an environment high in oil,
steam, or sulfuric gas.
These substances may have adverse effects on the
performance of the controller of damage its parts.
To reduce the risk of electric shock or malfunctions, do
not use a pointy or sharp object to operate the touch
panel.
Operate the controller within the temperature range
specification.
The use of controller outside of its specification may result
in serious damage to the controller. Be sure to check the
temperature range specification in the Instruction Book.
Use a security device such as a VPN router when
connecting the AG-150A to the Internet to prevent
unauthorized access.

* Upper-level and lower-level system controllers
The controller described in this manual can only be used as the upper-level controller, but not as a lower-level controller.
• Upper-level system controller (upper-level SC)
Upper-level SC refers to a controller that controls all other system controllers including the units they control.
If a given system has only one system controller, that controller becomes an upper-level controller.
Group settings and interlock settings can only be made from an upper-level controller.
• Lower-level system controller (lower-level SC)
Lower-level controller refers to a system controller that is controlled (including the units it controls) by an upper-level system controller.
