MULTICAL

602 is constructed with a view to fast and simple mounting as well as long-term, reliable operation at
the heat consumer’s.
Should you, however, experience an operating problem with the meter, the error detection table below may help
you clairfy the possible reason.
In connection with repair, if necessary, we recommend to replace only battery and temperature sensors and
communication modules. Alternatively, the entire meter must be replaced.
Major repairs must be made in our factory.
Before sending in the meter for repair, you must go through below error detection table to help clarify the possible
cause of the problem.
Symptom Possible cause Suggested corrections
No display function (blank
display) No power supply. Replace the battery or check the
mains supply. Is there 3.6 VDC on
terminal 60(+) and 61(-) ?
No accumulation of energy (e.g.
MWh) and volume (m
3
)
Read “info” on the display. Check the error indicated by the
info code (see section 6.8)
If “info” = 000, 16384 or 32768

Check that the flow direction
corresponds with the arrow on the
flow sensor
If “info” = 004, 008 or 012

Check the temperature sensors. If
defects are detected, replace the
sensor set.
If “info” = 4096 or 8192

There is air in the installation.
Ventilation necessary.
Accumulation of volume (m
3
),
but not of energy (e.g. MWh)
Inlet and outlet sensors have been
reversed, either during installation
or connection. Mount the sensors correctly
No accumulation of volume (m
3
) No volume pulses Check that the flow direction
corresponds with the arrow on the
flow sensor.
Check the flow sensor connection
Incorrect accumulation of
volume (m
3
)
Incorrect programming. If “info” =
128 or 2048

Check if the pulse figure on the
flow sensor corresponds with the
calculator
Incorrect temperature indication Defective temperature sensor
Insufficient installation
Replace the sensor set.
Check the installation
Temperature display is too low
or accumulated energy is too
little (e.g. MWh) Poor thermal sensor contact
Heat dissiptation
Sensor pockets too short
Place the sensors in the bottom of
the sensor pockets.
Insulate the sensor pockets.
Replace sensor pockets with
longer ones.
