: indicates a hazardous situation which, if not avoided, could result in death or serious injury.

: indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.

: addresses practices not related to personal injury, such as product and/or property damage.

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 injury, electric shock, or fire, do not alter or modify the controller.

To reduce the risk of electric shock, malfunction, smoke, or fire, do not touch the electrical parts or USB memory with wet fingers.

To reduce the risk of injury or electric shock, before spraying a chemical around the controller, stop the operation and cover the controller.

To reduce the risk of burns, do not touch the electrical parts with bare hands during and immediately after operation.

To reduce the risk of injury, keep children away while installing, inspecting, or repairing the controller.

Test runs, inspection, and service must be performed by qualified personnel in accordance with this manual. Incorrect use may result in injury, electric shock, malfunction, or fire.

If you notice any abnormality, stop the operation and turn off the controller. 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 frostbite, burns, injury, or electric shock, keep the equipment out of the reach of children.

[Main and Sub system controllers (M-NET)]

Each group can be controlled by a Main system controller or a Sub system controller.

EW-50 (AE-200/AE-50) is exclusively for use as a Main system controller and cannot be used as a Sub system controller.

Main system controller

Main system controller refers to a system 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 system controller.

Group settings and interlock settings can be made only from a Main system controller.

Sub system controller

Sub system controller refers to a system controller that is controlled by a Main system controller.

Caution:

Obtain an approval from the client for the following precautions as necessary.

1. The communication between EW-50 and the air conditioning units will stop while the software is being updated. Although the unit in operation may detect a communication error and an error sign may appear on the local remote controllers, the unit will continue its operation and be operable from the local remote controllers.

* Note that Mr. Slim indoor units or systems with no local remote controllers may detect a communication error and come to an abnormal stop.

2. Record the operation status of the air conditioning units immediately before updating the software. After the software update completes, check the operation status of the units, and manually operate the units as necessary.

3. Some operations and functions, such as scheduled operations, billing function, Peak Cut control, energy management function, will be disabled while the software is being updated. Check the setting details of these functions beforehand, and update the software when it does not affect these functions.

4. If the functions in the table below are used on the TG-2000A, avoid updating the software during the time period indicated in the right column.
