multidata
Installation and operating manual
Electronic energy calculator for heat meters
with 2 inputs/outputs
optionally with M-Bus, RS-232 and RS-485
All that counts.
General information
With multidata you have acquired one of the
most up-to-date, modern heat calculators cur-
rently available on the market.
Expressive symbols in the display and easy
menu navigation make readout simple. It can be
operated with one single button. The setting of
the data loggers (depending on the type of de-
vice) is being done via the software GMM.
The calculator is equipped with a long-life battery
made for operation during the initial verication
validity period (5 years) including a reserve of at
least another year. With a second battery you will
reach 11 years.
Initial verification
multidata is produced and tested in compliance
with the new European measuring instruments
directive (MID). According to this directive, de-
vices do no longer carry an initial verication
stamp, but rather the year of the device’s decla-
ration of conformity (recognizable on the front of
the device, for example: M09). The MID controls
the use of heat meters up to the moment they
are placed on the market resp. their rst putting
into use. After this, the national regulations for
devices subject to legal verication apply within
the EU.

Communication
If water meters with a potential free reed contact
are connected to the inputs the connection can
be made in any direction.
Take care of the polarity when connecting to a
BMS.
The connectors are given twice for the incoming
and outgoing of the M-bus wire.
Height: H = 106 mm
Width: B = 126 mm

At calculators with two pulse outputs typically the
rst output (I/O1) gives the energy and the sec -
ond (I/O2) the volume information.
The pulse value is permanently set and corre-
sponds to the last position of the associated dis-
play value.
Example:
Output 1 = energy output
Energy display = XXXXX.XX MWh
Last position = 0.01 MWh = 10 kWh
Output pulse = 10 KWh
The calculator can be ordered with two inputs op-
tionally. The pulse value can be called up in the
display (see the display overview, Level 1).
M-Bus (optional)
The optional M-Bus interface complies with the
norm EN 1434-3 and operates with 2400 baud
xed. It can be set to 300/9600 baud if neces -
sary.
The display resolution shall be selected such that
the display can not run over within a period of
one year.

Installation instructions
Safety instructions
The installation has to be done by qualied per -
sonnel. Read the instructions carefully right up to
the end before starting to mount the device.
The current laws and regulations have to be
observed, especially EN 1434 part 1+6, (in Ger-
many also AGFW directive FW202 and DIN 4713
part 4 and the initial verication directive).
At devices with communication interfaces or
mains supply the general technical rules and the
correspondent regulations have to be followed.
While demounting ow sensors and temperature
sensors make sure no heating water escapes
from the pipe – this can cause burns!
Close valves and release pressure before instal-
lation.
General Information
Take care of:
■ the display must readable at all times,
■ to avoid malfunctions due to other interfe-
rences do not install uorescent lamps, switch
cabinets or electric devices such as motors or
pumps in the immediate vicinity of the meter
(minimum distance 1 m),
■ all welding must be nished,
■ the ambient temperature must not exceed
55°C,
■ the type of temperature sensor must corres-
pond with the calculator,
■ the pulse value of the ow sensor must corres-
pond with the one from the calculator.
The calculator has 7 screwed cable glands for
wires with a diameter between 4,2 and 10 mm.
Keep unused glands closed.
Mind the connection order: temperature sensors
rst, ow sensor afterwards!
multidata is delivered ready for operation.
It does not need any settings or adjustings.

Installation heat calculator
ZENNER recommends to mount the calculator
on the wall. Do not mount the device at the pipe
or attach it directly on the ow sensor.
The mounting adapter at the backside of the cal-
culator can be used for rail mounting or for wall
mounting.
For wall mounting detach the adapter and turn it
180°, attach with at least two screws to the wall
and clip the calculator on it.
For rail mounting lift the adapter a little bit, place
the calculator on the rail and push the adapter
back until it locks.
Connection sensors
The mounting of the temperature sensors should
be done symmetrical with direct immersion.
If immersion sleeves are used they have to be
checked for conformity to MID and have to be
marked accordingly.
The installation of immersion sleeves has to be
done according to DIN EN 1434-2.
■ The sensor cables are marked with colors (red
= supply, blue = return).
■ Do not buckle, extend or shorten the wires!
■ Do only use paired sensors with the same se-
rial number on it.
■ At 2-wire systems the cable length of the tem-
perature sensor for supply and return should
not exceed 2.5 m for PT100, 12.5 m for PT500
and 20.0 m for PT1000.
■ At 4-wire systems the maximum cable length
is 20 m.
■ Consider EN 1434-2 regarding the diameter of
the wires.
■ Supply and return sensors must be inserted
into the immersion sleeves completely.
■ Installation points in the ow sensor can be
used for symmetrical installation of the tem-
perature sensors.
■ Seal temperature sensor after installation to
prevent unauthorized demounting (seals in-
cluded).
■ Do not wrap or install wires along hot pipes.
Switch 2-/4-wire
Calculators equipped with 4-wire measuring sys-
tem can be switched to 2-wire with the switch on
the top left side of the connection board.
Switch to the left for 2-wire, switch position on the
right for 4-wire measurement.
Rail mounting Wall mounting

Connection flow sensor
The total length of the wire between ow sensor
and calculator should not exceed 10 m.
With mechanical ow sensors the connection
order is optional. Mind the polarity at electronic
ow sensors.
External power supply
A small vertical line appears in the display when
the optional external power supply is on service.
In case of a failure of the external power sup-
ply the devices switches automatically to battery
supply. The battery lifetime can be checked in the
display (level 3). After having reached the date
the battery has to be replaced if needed.
Operation test
Check the calculator for any error codes in the
display after installation (see table for error
codes). Most of the errors can be deleted by
pressing the button. If the error appears perma-
nently, it will be detected at the next measuring
cycle and displayed again. Check weather the
volume information is updated and the displayed
temperatures correspond to the present ones
while the system is running (measuring cycle 2
minutes max.).
When attaching the top cover on the housing
pulses on the inputs can possibly be generated.
Check readings of the inputs and correct if ne-
ces sary.
Care instructions
Clean plastic surfaces with a damp cloth only.
Do not use any scouring or aggressive cleaning
agents! The device is maintenance-free during
the service life.
Sealing
Seal the device with the included seals to pre-
vent unauthorized opening.
Maintenance
Repairs or overhaul are only allowed by the
manufacturer or companies authorized by the
manufacturer.

operating states and does not always mean that the device is malfunctioning. However, should the symbol
be displayed over a longer period of time you should contact the service company.
