The Mitsubishi Electric Corporation EB-50GU-A/EB-50GU-J centralized controller features functions to allow users to monitor and operate air conditioning units and make initial settings from a PC via LAN. This manual explains how to make the initial settings for the EB-50GU-A/EB-50GU-J using a web browser.

Setting the Operating Environment
In the [Internet Protocol Version 4 (TCP/IPv4) Properties] window, check the radio button next to [Use the following IP address]. To monitor and operate the air conditioner from a PC without an Internet connection, follow the instructions below to set the environment for the web browser. To monitor and operate the air conditioner from a PC connecting to the Internet via a dial-up connection, follow the instructions below to set the environment for the web browser.
To monitor and operate the air conditioning units from a computer that connects to the Internet through a proxy server by connecting to an existing LAN, such as a LAN within your company, follow the instructions below to set the environment for the web browser set. In the [Local Area Network (LAN) Settings] window, check [Bypass proxy for local addresses] and click [Advanced].
Logging in to the Web Browser for Initial Settings
Note: A building manager uses the same username and password for the System Maintenance Engineer web browser. Note: It is recommended to change the default username and password so that users other than maintenance users and building administrators cannot change the settings. If a security certificate error page appears instead of the login screen, go to step (2) below. 2) If the security certificate is invalid, a security certificate error page will appear (as shown on the right).
Click [Continue to this website (not recommended)]. 3) If the connection is successful, the login screen will appear. Note: Even if the address bar turns red and the "Certificate Error" message appears, you can still access the web browser.
The date and time cannot be set on the EB-50 when the [Time Master] setting is set to [Sub]. In the [Schedule: Seasonal Setting] section, select [Available] to enable the weekly schedules and [Not available]. If the [Hold] setting is set to [ON] on the Condition List screen of the System Maintenance Technician web browser and the [Hold Type] on the above screen is set to [Forced], the [Hold] setting can only be canceled from the EB-50.
In the [Brightness sensor display] section, make the Show/Hide setting for the brightness/dark status detected by the built-in brightness sensor of the ME remote control (Smart ME controller). Register the groups of air conditioners, fans (LOSSNAY), Air To Water (PWFY) units, AHC or general equipment to be connected to the EB-50, and then click [Save Settings] to send the settings to the EB-50. 50. Set the interlocking conditions, then click [Save Settings] to send the settings to the EB-50.
Record the groups in each block, and then click [Save Settings] to send the settings to the EB-50.
In the [Kind of Errors] field, select the type of error from the following: [Unit Error], [Preliminary Unit Error], [Communication Error], [General Equipment], and [User Setting 1] to [User Setting 6 ]. Click [Functions 1] on the menu bar and then click [Peak Cut] to access the Peak Cut settings screen. Note: Peak Cut control cannot be performed on a DIDO controller (PAC-YG66DCA), AHC, or Air-to-Water Unit (PWFY).
In the [IP Address] field, enter the IP address of the Electric Amount Count PLC. The Peak Cut control setting corresponding to the control level 0 will be disregarded for the indoor unit groups in which the temperature difference between the set temperature and the room temperature is greater than the specified temperature difference. In the [Control Levels] section, the range of the electrical power must be set for each control level.
In the [IP Address] field, enter the IP address of the EB-50 to which the PI controller (with connection to the watt-hour meter used for the Peak Cut function) is connected. If five or more EB-50 units are used, use the Peak Cut method [Electric Amount Count PLC]. The Peak Cut control setting corresponding to control level 0 is ignored for the indoor unit groups in which the temperature difference between the target temperature and the room temperature is greater than the specified temperature difference.
Follow the instructions below to make the Peak Cut control settings for each control level for given outdoor units. For each control level, set the total time that the Peak Cut check is performed every 30 minutes. Follow the instructions below to make the Peak Cut control settings for each control level for given blocks of indoor units.
During Peak Cut control, the temperature set in Cool or Dry mode will be offset by +2ºC (+4ºF) and the temperature set in Heat mode will be offset by -2ºC (-4ºF). The time is set to  minutes, groups that are operated on the Peak Cut command cannot be operated by any controller.
Use night mode when quiet operation of the outdoor unit is preferred at night. Click [Functions 2] on the menu bar, and then click [Night Mode Schedule] to access the Night Mode Schedule settings screen. Note: The night mode schedule settings may not be available if you are logged in as a building administrator.
In the [Start Time] and [End Time] sections, specify the start and end times for Night mode. In the [Target Outdoor Units] section, select the M-NET addresses of the target outdoor units. The system switching function switches the operation modes of the indoor units connected to the same outdoor unit between cooling and heating based on the room temperature and the set temperature.
Click [Functions 2] on the menu bar, and then click [System-changeover] to enter the system changeover settings screen. The system change function is only available on the Y series of outdoor units whose operation modes do not include Auto mode. Note: Because the operating mode is selected based on the requirements of the representative group or the majority of groups, not all areas may be conditioned at the optimum temperature.
If the outdoor unit is an R2 series and whose operating modes include Auto mode, use Auto mode instead of System switching function to switch the operating mode automatically. The operating mode (cooling or heating) will be switched based on the requirements of the majority of all groups connected to the outdoor unit, taking into account the capacity of each indoor unit and the temperature differences between the set temperatures and the room temperature. Representative group The operating mode (cooling or heating) is switched based on the temperature difference between the set temperature and the room temperature.
Click [Functions 3] on the menu bar and then click [Interlock control] to open the Interlock Control settings screen. Set the interconnected conditions and actions, then click [Save Settings] to send the settings to the EB-50. Note: Interlock Control settings may not be accessible if you are logged in as a building administrator.
Note: Interlock Control is not effective when [External Input Setting] is set to [ON/OFF (Level Signal)]. Note: If a group is deleted in the group settings screen, be sure to delete the Interlock Control settings where the group is selected as input devices or output devices. Interlock Control verifies the state changes in ascending order from #1 to #150 every three to five seconds.
When the interleaving conditions are met, interleaving commands will be issued to the output units. By setting the interleaving conditions (input category, input states, and input units) and interleaving action settings (output unit type, action, and output unit) for each interleaving control setting, the operation of the output units can be linked to the operation of the input units. Note: When [External Input Setting] is set to [Emergency Stop (Level Signal)] (see Section 4-2-3) or when the indoor unit is stopped by Peak Cut control (see Section 5-2), only the lock control free contact and DIDO controller (PAC-YG66DCA) will be executed, but the other lock control will not.
Click [Select Input Units] to display one of the following screens depending on the selected input category. Note: If the selected operating mode is not available on the interlocked output units, the Interlock Control will not be performed. No actions will be taken for the Interlock Control setting set to [Disable].
Insert a step Inserts an empty row of Interlock Control settings above the row being displayed, and moves all rows down one step. Delete a step Deletes the row of Interlock Control settings being displayed, and shifts the rows below it up one step.
The path to the file to be imported to an external storage medium appears in the [Data import source] field.
