Specifications for communication with a local area network

Remote computer

| Processor at 1000 MHz, 256 MB RAM, 200 MB free hard disc space. Windows 2000 or higher. Java Runtime Environment Versión 6 Update 3 (2) or higher installed (included in the CD-ROM)

H-LINK

CSNET WEB v3 adds compatibility with the new version of H-LINK communication called H-LINK 2 while maintaining full compatibility with current H-LINK (H-LINK 1) units. Connection of both H-LINK 1 and H-LINK 2 units in the same H-LINK unit is possible considering the unit limitations and addressing. H-LINK 2 communication system adds new addressing for up to 64 Refrigerant Addresses and up to 64 Indoor Unit Addresses per Refrigerant Address. Also, H-LINK 2 adds an increased number of devices up to a maximum of 200 devices in the H-LINK 2 line. It is considered as a device a CSNET WEB, an indoor unit, an outdoor unit, or another device with an H-LINK address. PC-A1IO, KPI, or DX-Kit count as a normal indoor unit. The limitation for Indoor units is 160 at maximum, and for the Outdoor units is 64.    When there is a central control device like CSNET WEB, the maximum number of total units (Indoor and Outdoor units) is 176.

Compatibility with Central Stations
CSNET WEB is now compatible with PSC-A64GT & PSC-A64S central stations. By switching on Pin 7 of the option dip-switch, CSNET WEB activates the compatibility with the central stations. CSNET WEB has a preference over the central stations. If CSNET WEB is set in central mode a unit and Central Station tries to send an order, CSNET WEB will overwrite the order and restore the state of the unit that CSNETWEB has known. If CSNET WEB has configured the remote switch not available of a unit, the Central Station will not be able to remove that configuration. If CSNET WEB has configured the remote switch not available of a unit, the Central Station will not be able to remove that configuration. As part of this, the H-LINK line length could be up to 1000 meters, they could be increased to 5000 meters using up to 4 PSC-5HR. Each of them adds 1000 meters to the line, but it affects the capacity of the line.
Each H-LINK line repeater (PSC-5HR) counts as 16 indoor units.

Resume

Maximum number

Considering the previous maximums and the number of PSC-5HR, the maximum number of connectable devices with one central control, that case CSNET WEB, is shown in the following table and graphic. CSNET WEB v3 maintains compatibility with water chillers. Remember that the water chiller and packaged units cannot be connected to the same H-LINK line. CSNET WEB v3 requires DSW setting configuration to select between chiller and package.

CAUTION

• When this function is enabled, CSNET WEB requires a Central Station to communicate with the units. If no Central Station is controlling some units, it will cause important H-LINK communication problems.
• At Central Station compatibility mode, CSNET WEB does not detect the RCS Sensor, so it will not be displayed on system status and it will not be available to select as an input on the auto cool/heat operation.
• There are some variables in system status like liquid or gas temperature that will only be displayed after a value change. Those values are only asked by CSNET WEB after the change value, so after starting CSNET WEB they will be displayed as 0 until their value changes.

INSTALLATION

When unpacking the machine, check that it has not suffered damage during transport.

FASTENING
Perform the following procedure:

1. Remove the rubber supports
2. Unscrew the 4 screws from the top cover and remove it
3. Attach the box to the rear vertical board from the inside with M5 screws (not provided) and place 3 mm washers on the outside to separate the box from the wall.
4. Reinstall the top cover. Be careful to position it correctly.

CAUTION
Before applying power and turning on CSNET WEB you must ensure that:

• All the units and refrigerant circuits are under power and are running correctly.
• All H-Link connections have been set up. Any unit that is not connected or is not under power when turning on CSNET WEB, will not be recognized and will have to be configured later.

CAUTION
The signal cables should be as short as possible. Keep a distance of more than 150 mm from other power cables. Don’t wire them together (although they may intersect). If they must necessarily be installed together, take the following measures to avoid noise:

• Protect the signal cable with a metal tube that is earthed at one end.
• For communications, use shielded wire which is earthed at one end.

DANGER

• Always disconnect the power supply for CSNET WEB when handling the machine, to avoid electrical discharges.
• Do not connect the interface to the power supply until the installation has been completed.
• Comply strictly with local security codes and regulations when connecting the machine to the electric network.
• You will need a three-wire cable (two cores and earth) with a suitable plug at one end.

ELECTRICAL CONNECTIONS
To run, CSNET WEB will have to be connected to the electric network, to the transmission line with the air conditioners (H-Link), and to the Ethernet local area network (LAN).

The selection between the CSNET WEB Interface and the Computer identifies which element will execute the mail alarm function, and in each case, it will have different specifications. The differences between the configurations are:

Computer

• Configuring the mail alarms on the computer is used when CSNET WEB is on a LAN net that does not pass through a proxy to connect to the Internet.
• The mail alarms are being sent from the computer when CSNET WEB software is running so that the software cannot be closed.
• That connection allows the use of already existing SMTP servers on the Internet, such as Gmail, Yahoo, or others. These are encrypted connections, so they can be used.
• The e-mail sent has the location information column as it is managed from the computer and it is more powerful than the CSNET WEB interface.
• SMTP server can be encrypted. Gmail, Yahoo, or similar.

CSNET WEB Interface:

• Configuring the mail alarms on the CSNET WEB Interface is used when CSNET WEB is on a LAN that uses a proxy to connect to the Internet.
• CSNET WEB device will send the alarm mails using this SMPT server.
• It is required to have a SMPT server on the same LAN as CSNET WEB.
• CSNET WEB Interface cannot connect to a SMTP encrypted server

The account details configure the SMTP server. The next fields compose this configuration:

• Name : enter the installation name.
• E-mail : enter account installation mail.
• Delivery Server Address : set the mail server address.
• Server Port : set the mail server port.
• Username: enter the mail username.
• Password: enter the mail password. Notify settings configures who will receive the notifications and what will be the interval of these notifications.
• Notify interval: you can set a notification interval of 1, 2, 6, 12 hours, or 1 day.
• Notify E-Mail Address : sets the name and the e-mail address of the different receivers

Backup copy Clicking on the Backup button you can save your system configuration. If you want to restore it, you must click the Con Restore button.

BUILDING LAYOUT
CSNET WEB is supplied with a Building layout editor that lets the user customize their view and the way how the units are distributed through the installation.

The functions are the same as normal CSNET WEB, but there is a new user- friendly view. To control a Packaged or a Chiller unit just click on the area or the icon of the unit and start to work with the virtual remote controller.

Chiller has its remote controller and both controllers work like the “setting” tab of CSNET WEB. Layout file is set by entering in the field “Path of Building Layout Installation file” the corresponding path and file name assigned in the local computer

The Building Layout file creation is explained in the Technical Catalogue.

RCS WEB

INTRODUCTION
RCS Web software takes the idea to simplify CSNET WEB and use only the remote controller created for the Building Layout. The main idea is to install that software on the computers of users who need to manage all the CSNET WEB options. They will have only the same access as using the remote controller but from their computer.

NOTE

• It is available only for packages.
• The user will manage with the interface only the indoor units that the Installer allows him to manage.

RCS Web interface looks like a virtual remote controller that wants to simplify and improve the user experience controlling the units.

LOCAL SOFTWARE CONFIGURATION
After starting the software it will appear the main window. There, due to configuring the software it must be selected the configure button. To configure the installation will be needed the installer password, by default “Installer” is the username password.

NOTE
If the installer is set to white text its username and password it will be not asked. Installer configurations allow to configuration of the following items:

• Installation: set HARCS where RCS Web will connect.
• Unit filter: configure units that the user can see.
• User: set username, password, and privileges of the user.
• Proxy : configure proxy data if needed.
• Installer password : change the password to connect to the configuration

OPERATION WITH RCS WEB SOFTWARE
The main window opened is the login window. On that window, the user could introduce his username and password to log into the system. There are also small user configurations that are:

• Language selection: it allows switching the language that the software uses when it is started. Available languages are English, Español, Català, Italiano, Français, Deutsch, Nederland, Portugues, Czech, and Russian.
• Remind password : systems remember the last username and password configured to avoid the retyping of these items.
• Automatic login on startup: If the system remembers the password, it will automatically connect when the software is started.

NOTE

• If software is moved into the start-up menu of Windows it will be started when the computer is switched on.
• Marking automatic login on start-up, this window will not be shown.

The installation lists show the configured CSNET WEBS and whether they are connected or not. The state of connection will switch only when the user starts login in. Once the user is connected, it will appear an interface that looks like a remote control. This interface is equivalent to the building layout one with few improvements that help to be a central control. The controllable things will be Run/Stop, setting temperature, mode, fan, louver, and central. They are exactly like the Building layout remote control. It is possible to find more information in the Building Layout chapter. In the case of central it will be enabled only if the installer gives privileges to the user to control this, and when one central value is activated the buttons corresponding to that lockage will be disabled. Log out will return to the login window, and exit will close the application. The combo box on the upper part will be used to select between units if there is more than one. The displayed text will be the location field stored on the HARC. If this text does not exist, it will write “Unit:[X, Y, Z]” knowing that values as the slot, outdoor address, and indoor address of the unit. It also will show the state of the unit based on the text color. If the user closes the window using the cross button, the application will still run setting an icon on the system tray.

Clicking twice over the system tray icon will open the application. Using the right button of the mouse will open a little menu that will allow the user to close completely the application or open it.

Users will normally have the application closed on the system tray because it will not be always managing things. But having that icon there will be so useful due to the alarm notification.
When an alarm occurs system tray icon will switch to red color and it will be like this until the alarm disappears. An alarm displaying a message should be activated on the user configuration. The first time than alarm occurs it will appear a system notification will show that this alarm has appeared with the alarm code and unit address. Alarms could also be watched on the alarm lead of the virtual remote control or the unit’s list.
