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.
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
serious injury of death.
This symbol indicates that failure to follow the instructions exactly as stated poses the risk of
This symbol indicates that failure to follow the instructions exactly as stated poses the risk of
CAUTION
injury or damage to the controller.
WARNING
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
controller, electric shock, or fire.
Ask your dealer or an authorized technician to move or
reinstall the controller.
Improper installation may result in an electric shock or fire.
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.
CAUTION
Do not install the controller where there is a risk of
leaking flammable gas.
If the leaked gas accumulates around the controller, it may
ignite and cause an explosion.
Do not wash the unit with water.
Doing so may cause an electric shock or malfunction.
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 avoid the risk of electric shock or damage to the
controller, do not touch the touch p anel or USB storage
device connector 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 or damage its parts.
To avoid the risk of electric shock or damage to the
controller, do not press the touch panel with sharp
objects.
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.
If no security devices are installed, the operation settings
may be changed by an unauthorized person without the
knowledge of the user.

* Main and Sub system controllers
The controller described in this manual can only be used as a Main controller, not as a Sub controller.
• Main system controller (Main SC)
Main 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 a Main controller.
Group settings and interlock settings can only be made from a Main controller.
• Sub system controller (Sub SC)
Sub controller refers to a system controller that is controlled (including the units it controls) by a Main system controller.
