SMTP Server
SMTP server is used for transfer of electronic mails. If this field is left empty (standard option), SMTP server
of APATOR METRA will be used for sending the information e-mails.
Fill this field only if you want to use SMTP server of your Internet provider. For exact setting please contact
your Internet provider.
E-mail address for sending error logs
You will receive information e-mail with error logs to this e-mail address. You will get e-mail only when
system detects some error. Following events are considered as error:
•
device was not detected by the system for the set number of days (typicaly 7 days),
•
electronic seal in device was broken,
•
backflow in water meter is bigger than set value.
Error logs are sent in standard HTML format for Internet browser and are compressed in ZIP archive. We
recommend you to pay increased attention to these messages. It is better to use different e-mail address
than for everyday readings. You can also view error logs in page with evaluation of readings or download
them packed in ZIP archive at any time. If you forget your login credentials to the system, you can have it
sent to this email address.Therefore we strongly recommend to fill this item.
Excessive backflow
Enter here limit for maximal backflow in percentage. In case that water meter backflow will exceed set value,
system will interpret this situation as an error. This is indicated in page with evaluation of readings. If you set
sending of information e-mails with error logs, you will also get e-mail notification.
For this purpose backflow is calculated as percentage ratio
backflow in past billing period / forward flow in past billing period.
In case that there is no forward consumption in past billing period (usually because no billing period is closed
already), ratio is calculated from cumulative consumptions from moment of installation
current back-flow / current forward flow.
If water meter is installed in opposite direction (i.e. no forward flow and high back-flow), system interpret ratio
as 100 %.
Missing read device
If the read device (heat cost allocator or radio module for water meter) is not found for set number of days, it
will be consider as missing. So it will be mentioned in the main page and it will be put to the error log that is
sent by e-mail to the operator. This setting will also affect the installation - after set time system finishes the
installation and switch to the routine operation. If the field is let empty, system use standard setting (7 days).
