CRC-Code
If the respective operation thresholds are exceeded and flow
and temperature difference are positive, the meter summates
the energy and the volume.
For a positive flow the activity display
Code entry for test /
loop in the LCD.
para operation
All segments of the display are switched on for control purpos-
es during the segment test. The flow, power and temperature
difference are recorded with the appropriate +/- signs.
The operating hours are counted from the first connection of
the power supply. The meter saves "operating time with flow"
as soon as a positive flow is recognized. Missing hours are
summated if there is a fault and the meter is thus unable to
take a measurement.
Stored maximum values are marked with an „
right hand area of the LCD.

Parameterization
Getting started
Open the slide valves slowly.
Check the heating system for leak-tightness.
Vent the heating system carefully.
Press the button on the meter briefly.
Check the measured values for flow and temperatures for
plausibility.
If needed vent the heating system until the flow display is
stable.
Fit the user locks to the fittings and the temperature sen-
sors. The scope of supply includes two self lock seals for
sealing a sensor and the connecting fitting.
Read the meter status for energy, volume, operation and
missing time and note the values.
Error "incorrect flow direction (negative)"
Check that the flow direction arrows on the volume measurement unit
match the flow direction of the system. If the directions do not match,
turn the volume measurement unit by 180°.
Error "negative temperature difference"
Check whether the sensors are installed in the right circular flow (flow
and return flow interchanged). Use only a meter suitable to the mount-
ing place.
Heat meter:
Temperature sensor in the flow-pipe with higher temperatures; temper-
ature sensor in return-pipe with lower temperature
Cooling meter:
Temperature sensor in the flow-pipe with lower temperatures; tempera-
ture sensor in return-pipe with higher temperature
