The external and internal temperatures, and the voltage and frequency of the available power system are required as input parameters. On this basis, the program determines appropriate selections of wall- and roof-mounted climate control units from the following categories: • Fans • Air/air heat exchangers • Cooling units • Air/water heat exchangers • Heating units • Climate control doors The program also takes into account the geometry of the available climate control units and specifies only those units which are suitable for the selected enclosures. The 30-day trial version asks the user to enter an unlock code 30 days after the first program start. With this code, the program is identified as a full version and then runs without time limitations. After registration at http://www.rittal.com/registration, you will automatically receive a copy of each new CD version. When Therm 6.0 is started, a software package integrating the Windows operating system, an Apache-compatible server, a MySQL database and a PHP interpreter is installed on your computer. Such packages are referred to as WAMPs for short. The installation is performed with the tool Microweb from IndigoStar in the version 2.00 dated 12 April 2007. Subsequently, the browser is opened automatically and the Therm start page is displayed. Therm 6.0 uses HTML, JavaScript, PHP version 5.1.4, MySQL version 5.0.27 and ionCube PHP Encoder 6.5.13. PHP is a server-side programming language which can be incorporated into the HTML pages of Web applications. When a page is called, the PHP code contained on that page (together with any files required by this code) is read, parsed and executed; the finished page is then output to the browser. MySQL is a SQL relational database which stores its data in the form of tables. It has also been handling the database activities of SAP since May 2003. The database system SAP DB has been renamed MaxDB and is now based on the MySQL core. Created 10.2012 Page 3 of 32 Rittal Therm 6.2 User Manual ionCube PHP Encoder is a PHP accelerator and encoder solution. It accelerates PHP scripts by saving them in their compiled state, eliminating the need for compilation at runtime. A number of other optimised features also serve to speed up script execution. 2 2.1 Installation System requirements The following minimum system requirements should be observed to allow smooth working: • 500 MB free hard disk space • UTF8-enabled browser; the following browsers have been tested: o Microsoft Internet Explorer 5.5, 6.0 and 7.0 o Mozilla Firefox 3.0 o Opera 8.54 and 9.63 • CPU with 1.8 GHz clock rate • Windows 2000 or XP: o Pentium 4, Celeron or equivalent AMD processor o 512 MB RAM • Windows Vista: o Dual-Core or equivalent processor o 1 GB RAM 2.2 Setup The program starts automatically from the CD if the “Autostart” function is enabled for the CD drive. Otherwise, it can also be started manually by double-clicking the file “microweb.exe”. All data are stored in a MySQL database. To enable writing to the database, the data are copied to the temporary folder of your Windows installation when Therm is started for the first time. You can find out where this is on your local PC by opening the MS DOS command prompt and entering “echo %TEMP%”. You can accelerate the execution of Therm by installing the software on your computer. To do so, it is sufficient to copy the whole contents of the CD to your local PC and to run the file “microweb.exe” from there. The setup program will create appropriate links for the Start menu and the Desktop, as well as the required uninstaller information. To run the setup program, double-click the file “setup.exe” in the root folder of the CD. Follow the setup instructions which appear on the screen. It is not necessary to restart the computer. Created 10.2012 Page 4 of 32 Rittal Therm 6.2 User Manual The installer and uninstaller programs are multilingual and start in the language of your installed Windows operating system. The user must possess write authorisation for the temporary folder, as this is where the databases, projects and import/export files are stored. It must be possible to modify these files during the application runtime. The installation creates a program folder as specified by the user. The default folder is “C:\Program Files\Rittal\ApplicationName”, but this path can be changed freely by the user. If the specified folder does not yet exist, it will be created. Further subfolders are created within the selected installation folder: ...\ApplicationName\firefox ...\ ApplicationName\htdocs ...\ ApplicationName\mysql ...\ ApplicationName\php Modifiable files are managed in the temporary folder, where the following subfolders are installed ...\microweb\localhost\mysql\data00xx ...\ ApplicationName\projekte (projects) ...\ ApplicationName\sicherung (backups) ...\ ApplicationName\verlustdaten (heat loss data) All files are installed locally. 3 Deinstallation Deinstallation removes the installed files, folders and Windows registry entries, with the exception of the data in the temporary folder. Note: If an installation folder contains files or subfolders which were not installed or created by the Therm application itself, these files and subfolders will not be deleted. 4 General notes on the user interface The user interface is based on the Microsoft Windows standard GUI, i.e. it comprises • a menu bar in text form • a working area Created 10.2012 Page 5 of 32 Rittal Therm 6.2 User Manual Note: The main menu bar remains visible for the whole program runtime. 5 Welcome screen The welcome screen comprises a Flash animation and an alternative page which is called automatically if Adobe Flash is not installed on the computer concerned. To be able to use the full functionality of the program, you should install the latest Flash version, which can be obtained from http://get.adobe.com/de/flashplayer/. The desired language can here be set by way of the mouse-sensitive image area “Change language” which can be seen on the screen depicted below, or else changed at any other time during program execution. The language selection will influence not only the user interface texts, but also the displayed addresses and the date format. Created 10.2012 Page 6 of 32 Rittal Therm 6.2 User Manual If you click on the link “Do not show this screen again”, the start screen will be skipped when Therm is called the next time.

Pressure Drop 6.2 for Windows calculates the pressure losses caused by the friction of a liquid or gas flowing through a pipe (both laminar and turbulent flows); in addition, it is possible to calculate pressure changes related to the geodetic height (pipe runs upwards) and changes in kinetic energy. Besides simple pipes, the program calculations take into account also the losses attributable to pipe fittings (changes of direction, etc.) and various accessories (valves, expansion compensator, etc.). The individual elements can be combined freely, permitting calculation of an overall pressure drop. To be able to calculate a pressure drop, the program requires corresponding data to describe both the pipes (roughness) and the flow media (density, viscosity). For typical pipes and many liquids and gases, including mixtures, these data can be taken directly from the program's own databases. A further user-defined database enables you to save and recall data for any individually used media. Further infos and answers to frequently asked questions (in German, English, French and Dutch) can be found at http://www.pressure-drop.com. The shareware version of this program can be found in the Therm subfolder \htdocs\Druckverlust. 8.2 Menu function “Maintenance and commissioning” This function opens a PDF file with detailed information on the topic of “Maintenance and commissioning”.

For example, the express mode only permits calculation of the climate control for a single enclosure. The heat loss values, furthermore, can only be entered directly, whereas they can be determined from measured temperatures or lists in the expert mode. Created 10.2012 Page 23 of 32 Rittal Therm 6.2 12 User Manual Calculation The calculations to determine the suitable climate control units for a particular cooling problem take into account not only the ambient conditions and the specified heat losses, but also the geometry specifications of the selected enclosure. Each calculation is structured over 5 tabs • Project data • Enclosure selection • Calculation • Accessories • Summary The parameters “Max. external temperature”, “Max. internal temperature”, “Voltage” and “Frequency” can be modified at any time during calculation. The “Project data” tab contains general project information to enable the project to be identified in the overview table and in the results summary. Three special cases are taken into account under “Enclosure selection: • The product group “SO” denotes special enclosures whose dimensions and k-factor can be specified freely Created 10.2012 Page 24 of 32 Rittal Therm 6.2 User Manual • TS encloses can be combined into suites if the heights and depths of the enclosures are identical • CP 6372.009, 6382.009, 6292.009, 6292.109 and 6392.209 are operating housings with variable depths and surfaces When you click on the button “Save enclosure”, a message box is displayed to ask whether heat loss data are to be assigned to the selected enclosure. If no data are to be entered at this point, you must select “Cancel”. When you click on “OK”, a new window is opened with three tabs: • Direct input • Measured temperature • Device list Created 10.2012 Page 25 of 32 Rittal Therm 6.2 User Manual Subsequently, you can select further enclosures and – if appropriate – then combine them into a suite in a new window. It is only possible to combine enclosures into a suite in the case of TS enclosures of identical height and width, subject furthermore to the specification of correct enclosure position types (end and centre enclosures). Created 10.2012 Page 26 of 32 Rittal Therm 6.2 User Manual The calculated results are displayed on the “Calculation” tab. On the basis of these results, a climate control recommendation can be called up by clicking on the buttons corresponding to different types of climate control unit. Fans and air/air heat exchangers can only be selected if the maximum external temperature is colder than the maximum permissible internal temperature. Otherwise, the external air would not be able to cool the enclosure interior to the desired temperature. Furthermore, no climate control units are displayed if no cooling is necessary, i.e. the prescribed internal temperature is already observed without climate control. One special case relates to calculations for outdoor installation: The results are here derived from empirical measurement data. Such measurements have to date only been performed for enclosures of the CS product group, and even then permit only a very limited selection of installed devices.

If two cooling units are selected, the connecting cable will also be offered automatically. The tab “Summary” serves to document the defined project. The button “GM” creates a file in a special file format used by General Motors. The buttons “XML”, “HTM” and “TXT” serve to output the calculation results in the respective formats. 13 Interface The subfolder “htdocs/interface” contains three example files: “data.txt”, “data.xml” and “startdatatransfer.bat”. These three files contain comments describing the interface for data transfer to Therm. You can open either of the files “data.txt” or “data.xml” with a text editor of your choice and can then enter data for use in Therm. The file “data.txt” possesses a simpler data structure, but is limited to one enclosure and a maximum of 20 devices with heat loss data. If the project in hand is more complex, then it is necessary to use the file “data.xml”. The process of data transfer to Therm is started with the batch file “startdatatransfer.bat”, in which it is specified, which of the two text files is to be read. The batch file then starts the Therm software and displays the project overview. 14 File “microweb.ini” The file “microweb.ini” is to be found in the root folder of Therm. It is a text file containing setting parameters and can be opened in the text editor with a doubleclick. The following parameters can be edited there: • Name of the Web page in the browser: o hostName=localhost The real host with this name will then be temporarily unattainable, however, because the IP is saved intermediately by the browser. The value • hostname=default tells Microweb to take the host name of the computer on which it is currently running. Port number of the Web page: o Normally, Microweb will always assign a port number which is not in use. It is also possible, however, to assign a specific port number: port=4001 • Browser selection: o Microweb starts the default browser. It is also possible, however, to select a different browser with one of the following entries: Created 10.2012 Page 30 of 32 Rittal Therm 6.2 User Manual browser=ie browser=netscape browser=none Furthermore, you can start a browser from the command line with one of the following commands: -browser=ie -browser=netscape -browser=none If no browser is selected, the only way to close the Web server is to press CTRL-ALT-DEL or else to terminate the program via the Task Manager menu. A warning message will be displayed, but can be ignored in this case. You can also start a specific different browser using the following command line: browserpath=<path to the browser to be started> The location can be specified either as an absolute path or relative to the server root directory. To start the browser in kiosk mode, you should use the following entry: browseroptions=-k • Use of a MySQL database: o Microweb automatically copies the whole contents of “mysql\data” into a temporary folder when it is started for the first time. If you are not running Therm from a CD, you can deactivate this copying with the following entry: CopyMysqlFiles=0 The working copy of the data is only created when Microweb is used for the first time. If Microweb is to copy the data again, it is necessary to change the version number of the database: DatabaseVersion=0043 The value can be any valid folder name. It is appended to the path to the working copy of the database. If a MySQL database server is already running on the target computer, you must use an alternative port. To change the MySQL server port number, use the following entry: Created 10.2012 Page 31 of 32 Rittal Therm 6.2 User Manual OnStart=%%$server_root\mysql\bin\mysqld%% --skip-innodb -standalone -- basedir=%%$unix_server_root/mysql%% -datadir=%%$mysql_data_dir%% -- port=3000 OnExit=%%$server_root\mysql\bin\mysqladmin%% --user=root -- • port=3000 shutdown Note that pairs of percentage signs must be used in place of a quotation mark in the INI file. Permit display of folder contents: o AllowListing=1 • Permit remote access from other computers: o By default, a Web page can only be viewed on the PC on which it is running. The following entry also permits viewing from other computers on the network: allowRemoteAccess=1 Created 10.2012 Page 32 of 32
