The demonstration copies retain all the functionality of the full programs, they are just limited on the size of the project data that can be entered. Please follow this link for a description of the demonstration limits for the ECA program. In addition to these reports the built-in pipe data, fitting data, and soil data can be printed. The user can specify exactly what reports are to be printed, the left hand margin, and starting page number. All reports can be printed to the screen or printer.
All input data is checked at the time of entry so that no improper data can be entered.
Upon completion of the input process, all data is saved to disk and can be reviewed and edited whenever desired. The general project data includes the project name and location, client and designer names, the building heating and cooling loads, the summer and winter design conditions, and the soil thermal properties. Input sheets are provided for the easy organization of your data. The computer must have floppy drives or a hard disk drive.
