Code
Meaning
F-1
Temperature sensor faulty. Exchange the device and return it.
F-3
The outlet sensor registers a higher temperature than the inlet sensor. Check whether the
heat meter / the sensors are in the correct sections.
F-4
Flow sensors faulty. Exchange the device and return it.
F-5
Heat meter measures faultlessly. - In order to save electricity, the optical interface is tempo-
rarily out of operation.
F-6
The flow direction of the volume measuring section is incorrect. Check the installation
direction.
C-1
The meter has a permanent fault and must be replaced. The readout values cannot be used.
All error displays except C1 are alternating displays which change every 2 seconds,
displaying the cumulated energy since commissioning. In contrast, error display C1 is
exclusive, i.e. if this error occurs no alternative display is possible.
If several of the errors indicated by the other displays occur simultaneously, the meter dis-
plays the higher priority display error. The display priority order is
F4
,
F1
,
F6
,
F3
,
F9
and
F5
.
In addition to the error displays as such, a warning triangle is superimposed in all the
displays except the "Everything off" display test. Example:
