Evaluation of the logger files

The logged values are saved in *.csv files (Comma-Separated
Values) directly on the NWPM expansion. After the files have
been downloaded and saved on the hard drive, they can be read
into a spreadsheet program. The import function for external data
should be used for this. The formatting must be set during the im-
port. Please note that the data format of the columns is imported
as "text". Once the import is complete, the data can be proc-
essed further and displayed in graph form, for example.

5.5 Users preferences

It is often necessary to display information on the heat pump with
system-specific information for presentation purposes, particu-
larly in showrooms. Presentation pages are available for this pur-
pose at http://ihre-ip/http/start. No settings can be made on the
system via this page, but additional information and details can
be saved. This information can be added in the "users prefer-
ences" menu.

5.6 Web page passwords

Via the "Web Page Passwords" menu, a username and pass-
word can be assigned for folders which should not be accessed.
Clicking on the link accesses the "admin" folder and a username
and password may be requested. The username "admin" and
password "fadmin" should be selected as standard. The NWPM
expansion then appears in the folder structure.
 Example of the folder structure
The "index" folder contains files where changes can be made to
settings on the heat pump. No changes can be made to settings
in all other folders.

 Password allocation
If a username and password have been allocated, they can be
changed at any time using the described procedure. If the entries
are to be deleted completely, an FTP access has to be set up
and the .htpasswd file in the relevant folder deleted.
NOTE
For access with the HeatPumpApp, the username and password for the
"admin" folder is required.

5.7 FTP password

Under the "FTP Password" menu, the password for the FTP ac-
cess can be changed. FTP access may be required for updating
the user interface.
