General information
With multidata you have acquired one of the
most up-to-date, modern heat calculator cur-
rently available on the market.
The calculator for changeover heating/cooling
meters can be identied by the inscription “change
over” on the front of the body, the cooling meters
by the inscription “cooling”. Calculators for heat-
ing meters only don’t have any specic inscription.
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 device) is being done via the software
GMM.
The calculator is equipped with a long-life battery
made for operation during the initial verication
validity period (5 years) including a reserve of at
least another year. With a second battery you will
reach 11 years.

If water meters with a potential free reed con-
tact are connected to the inputs there are free
of polarity.
Take care of the polarity when the pulse outputs
are connected to BMS.
The connectors are given twice for the incoming
and outgoing of the M-bus wire.

Communication
At calculators for changeover heating/cooling me-
ters the rst pulse output (l/O 1) gives the heating
energy and the second output (I/O 2) the cooling
energy information.
The pulse value is permanently set and corre-
sponds with the last position of the associated
display 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 necessary.
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 qualied 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 verication 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
At cooling meters for use within German metrol-
ogy all the components must be calibrated and
labelled accordingly.
For use as changeover heating/cooling meters
all the components must be labelled both for EC
conformity declaration and or national initial veri-
cation.
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!

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 immer-
sion sleeves has to be done according to DIN
EN 1434-2.
■The sensor cables are marked with colors (red
= supply, blue = return with respect to the heat-
ing system).
■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 20m 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.

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 or-
der is not relevant.
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 dis-
play (level 3). After having reached the date the
battery has to be replaced if needed.
Operation test
Check the changeover heating/cooling meters
after installation for any error code (installation
error); errors see table for error codes Most of
the errors can be deleted by pressing the button.
If the error appears permanently, it will be de-
tected at the next measuring cycle and displayed
again.
Check weather the volume information is updat-
ed 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-
cessary.
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.
Care instructions
Clean plastic surfaces with a damp cloth only.
Do not use any scouring or aggressive cleaning
The device is maintenance-free during
the service life.

Status display / Error codes
The symbols in the table below show the meter’s operational status. The status messages only appear
in the main display (energy)! The temporary display of the warning triangle can be caused by special
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.
Error codes show faults detected by multidata. If more than one error appears, the sum of the error
codes is displayed: Error 1005 = error 1000 and error 5.
