The displayed number depends on the user configuration. If "0" is configured for the given group, the
group is disabled from recording.
This reading is followed by a cycled display of successive values in the record; at the beginning of each
record shows a message which record will be displayed at the given moment and how many records
have been registered, e.g.
010-010
the 10th registration (the latest) out of 10 is displayed.
Short press of the push-button displays the next written record - see the screen image below:
009-010
the 9th registration (the second latest) out of 10.
If the record is corrupted, (the CRC of the data in the record is incorrect), the record number will be
displayed alternately with the error message. Example (see below): the messages will be displayed
alternately to alert that the data is incorrect.
009-010
Error
If the next registration increases the number of registrations above the maximum (set by the user),
the 4 oldest registrations will be deleted and the new one written. Hence the displayed number of re-
gistrations will decrease by 3 and increase by 1 after the next write, etc. If the next registration occurs
when the archive is viewed, the registration data display will be stopped and restarted by showing the
number of maximum registrations for the specific archive group. If during the display of data in group
2 or 3 a configuration write of registration cycles is made, the display will be stopped and the LCD will
revert to group 1 of basic data.
If the symbol flashes when displaying the actual data, an error has occurred and the error code is
not zero.
If is displayed, there is flow in the direction of counting volume and heat.
The symbol means that the current flow direction is wrong. When very small flows occur, the direction
symbols will appear shortly.
The symbol means that the jumper is installed and writing of calibration and configuration data is
possible.
The LCD returns to the actual data display and shows the heat consumption in any operating mode if
the push-button is not operated for ca. 3 minutes.
The annexes feature figures which provide guidance on operating the LCD.
Annex A shows the display in the basic operating mode of the heat meter with the recording configured
to disable monthly and annual registrations.
Annex B shows the display of monthly and annual registrations provided that they are active and correct.
If the heat meter is unable to correctly read the configuration or consumption data
following battery replacement, its operation is halted and the following message
is displayed:
Error
The user can only call the technical service.
