5. Installation
The prescriptions related in the standard EN1434-6 must be respected when the
Supestatic 749 is installed.
In the standard version, the calculator is parameterised by default for installation on the “cold”
pipe side. Installation on the “hot” pipe side must be specied with the order.
Depending on version and use (heat and/or cooling meter), the energy meter must be tted on
the “cold” or “hot” pipe side of the installa-tion in compliance with the chosen conguration. If
the device was ordered with the conguration option, some parameters can be changed using
the “Cong” menu during commissioning.
In a same installation, mixed mounting positions (horizontal and vertical) can be realized.
Place the ow meter correctly according to the direction of the uid (an arrow  can be seen
on the ow meter).
Horizontal mounting with the integrator facing downwards is not permitted. Also avoid tting in
a position which may cause an air bubble to build up inside the mechanical meter.
The energy meter must be tted between two shutoff valves. The ow meter must be installed
ahead of any monitoring valves so as to avoid any potentially interfering inuence. Waterproof
will be checked at the various mounting points.
The heat conveying liquid must be equivalent to water without any additives according to
standard FW510 of the AGFW (German District Heating Association). If additives are added to the
water, the user must ensure the compatibility of the materials used in the thermal energy meter
which are in contact with these additives.
5.1 Mounting of the calculator for a cooling application
Only the ow meter can be fully isolated. Separate the calculator from the ow meter and x
using the wall support aid.
It is recommended to separate the calculator from the ow meter and installed at a sufcient
distance from the ow meter if:
- The meter has to be installed in a conned space
- The meter is in connection with mounting in condensing environments
- To prolong the battery life time
The pipes are generally free from air before the installation is brought into service. Follow the
insulation instructions for cooling installations. Final commissioning must be performed and
documented.
Horizontal mounting position:
The sensor head MUST be placed to the side
+/- 45° in relation to the pipe axis to avoid
inuences of air inclusions (top) or dirt (bottom).
Vertical mounting position:
Mounting in riser or down pipes possible.
After mounting and before commissioning purge system > 10 min at qp to
avoid air bubbles.

Instruction for use | Superstatic 749
5.2 Wall mounting of the calculator
The calculator can be separated from the ow meter and xed against a wall using the wall
xing component, together with a double-sided adhesive tab delivered with the Superstatic 749
(Figure 1). If possible, install the wall xing component above the ow meter.
The wall xing component can also be screwed on to the wall (screws are not supplied).
To separate the calculator from the ow meter press laterally with one hand on the two locking
buttons, while pulling the calculator upwards (Figure 2).
Fix the calculator onto the wall xing component taking care not to jam the cable which
connects the calculator to the ow meter and stick the adhesive tab behind the wall component.
Secure the assembly to the wall (Figure 3).
Figure 1 Figure 2 Figure 3
To remove the calculator from the wall support, it will be sufcient to press laterally on the two
locking buttons while pulling the assembly towards you.

12 Instruction for use | Superstatic 749
5.3 Mounting of the temperature sensors
The temperature sensor in the ow meter has no black frame marking on the label.
The temperature sensor with the black frame mark on the label indicates that the sensor must
be mounted in the pipe “opposite” to the Superstatic 749.
Example: If the ow meter is installed on the warm side (Hot Pipe), the temperature sensor with
the black frame mark will be mounted in the cold side (Cold Pipe).
The Superstatic 749 is delivered with temperature sensors having a cable length of 1.5 m.
The temperature sensors form a sub-assembly with the calculator. The temperature sensor
cables must be neither shortened nor lengthened.
The temperatures of use displayed on the label must be respected.
A temperature sensor may be tted directly in the Superstatic 749 ow meter. The temperature
sensors will preferably be tted directly, in other words one temperature sensor will be tted in
the ow meter while the other sensor will be installed on the other side of the heat exchanging
circuit.
Note: The temperature sensors will be xed with a plastic nut. This plastic nut consists of two
half-nuts held together by a rubber band. If the rubber band is removed from the nut, the two
nut halves will no longer be held together on the temperature sensor and one or both nut halves
may separate from the temperature sensor.
1. Remove the O-ring from the temperature sensor. Be careful not to remove the rubber band
(symbolized by the letter "E" on the drawing) from the nut as it may separate into two parts
and fall on the oor.
2. Fit the O-ring on the mounting template pin.
3. Insert the O-ring by rotating it using the tting template in the position provided for the ball valve.
4. Position the O-ring denitively with the other at end of the tting tem-plate.
5. Insert the temperature sensor with the two half-nuts in the thread M10x1 of the ball valve
and screw down by hand as far as it will go (maximum tightening torque of 1 Nm).
Note: The mounting template pin is not included in the delivery and can be ordered separately
(Article number: 0460P348).
When sensor pockets are employed, these must be used specically for the two temperature
sensors and must correspond to the list set out below.
Asymmetrical mounting is also possible. In that case the temperature sensor having a cable
marked with black frame will be tted in the other side of the heat exchanging circuit in a sensor
pocket dened according to the table set out below.
For applications with non-symmetrical integrated temperature sensor pair restricted rated
operating conditions are to be in accordance with the lower limit of the ow value and the lower
limit of the temperature difference: qi ≥ 200 l/h at ∆Tmin = 3K or qi ≥ 60 l/h at ∆Tmin ≥ 6 K.
Make sure that the sensors are mounted until they stall with the bottom of the sensor pocket.

Pulse input function
The Superstatic 749 offers the possibility of integrating up to two further pulse input from other
meters, for instance a hot water and a cold water meter.
The value of the pulse factor is programmable via the Prog7x9 software. By default, the pulse
factor will be 1 Pulse/Unit for each pulse input.
The meter data are aggregated separately in totalizers and can be shown on the display as IN1
and IN2; they can also be transferred via the communication interface which is installed in the
calculator. The Superstatic 749 is delivered with a cable length of 1.5 m for the input pulse sig-
nals.
Pulse output function
If ordered the Superstatic 749 offers the possibility of integrating two open collectors pulse
outputs which can represent hot energy, cold energy or volume.
Energy Meter – heating or cooling application:
- Output S1 = Heating or cooling energy
- Output S2 = Volume
Mixed application heating and cooling:
- Output S1 = Heating energy
- Output S2 = Cooling energy
Whenever the smallest energy unit (hot or/and cold) or volume displayed on the screen is
incremented, 1 pulse will be transmitted on the corresponding output cable S1/S2.
Example for energy:
Display 12345678 kWh ==> output pulse value for energy = 1 kWh / pulse
Display 12345,678 MWh ==> output pulse value for energy = 0.001 MWh / pulse
Display 123456,78 GJ ==> output pulse value for energy = 0.01 GJ / pulse
Example for volume:
Display 12345,678 m3==> output pulse value for volume = 0.001 m3/ pulse
Display 123456,78 m3==> output pulse value for volume = 0.01 m3/ pulse
The Superstatic 749 is supplied with a cable length of 1.5 m for pulse outputs.
Electrical characteristics of the pulse outputs: open collector 1 Hz 500 ms.
Optical interface
The optical interface is available on every Superstatic 749.
Communication between the Prog7x9 software and Superstatic 749 can be done by means of an
optical coupler.
The Prog7x9 software is mainly used to congure the non-metrological parameters and for
readout.
The transmission speed is set at 2400 bauds and cannot be changed.
We recommend the use of optical couplers supplied by: www.petechnik.de
Should communication problems occur, please refer to the document User Guide Prog7x9
(integrated as PDF in the software).
For the optical probe listed below, we have noted the lters needed to permit correct
communication with Prog7x9 software:

Instruction for use | Superstatic 749
10.1 SONTEX Radio
10.2 wM-Bus Radio / OMS
10.3 LoRaWAN®
The SONTEX Radio communication interface supports communication between all Sontex prod-
ucts having this interface. It must be specied when ordering. The radio module will then be
installed and congured in the factory.
The SONTEX Radio interfaces make use of a bidirectional radio technology which is a highly
reliable and performant solution for a remote metering system (xed or mobile). The technology
employed is based on Radian 0 protocol and works at a frequency of 433.82 MHz.
The products tted with this Radio module can be accessed 365 days a year from 06:00 to 20:00.
The radio address is displayed in the Service menu if it corresponds to the serial number of the
Superstatic 749.
Technical data
Bidirectional communication; FSK Modulation; Frequency 433.82 MHz; Radian 0 radio protocol,
transmission power: 10 dBm (10 mW)
The life cycle is calculated for normal metering. Factors such as: the environmental temperature
during use, the number of readings taken etc. inuence the battery service life.
The Wireless M-Bus module is used to transfer data according to the wM-Bus (EN13757-4) radio
communication protocol and in compliance with the OMS (Open Metering System) Release V4.
To have this interface provided in the Superstatic 749, it is necessary to specify when ordering.
The Wireless M-bus module will be installed and congured at the factory. A specic notice will
be added to the standard documentation.
Technical data
Unidirectional communication, Frequency 868.95 MHz, Mode 5 or 7, Radio telegram C1 or T1,
transmission power: 14 dBm (25 mW)
A LoRa enabled device can be identied as such if the product label is marked “LoRa”. First of all,
the LoRa device must be registered on a LoRaWAN network.
The registration of the device on the network will be done by a JOIN request that can be
started from the Prog7x9 software or directly on the device via the LCD screen.
To register the device on the network, please follow the sequence below:

10.4 Powered remote M-Bus
The powered remote M-Bus communication interface is a serial interface which permits com-
munication between different M-Bus devices via a central M-Bus station. It must be specied
when ordering. The powered remote M-Bus module will hence be installed and congured in
the factory.
By default, the primary address will be congured with the address 0 and the secondary address
will correspond to the serial number of the Superstatic 749. To change the value of the secondary
address, you must use the Prog7x9 software or send M-Bus specic orders. The secondary
address corresponds to the identication eld ID. The primary address is displayed in the Service
menu with the indication [Addr:].
Technical data for the M-bus communication system:
M-Bus protocol compliant with standard EN 1434-3; free potential interfacing without polarity
(the voltage measured on the last device must exceed 36VDC); transmission speed 300/2400
Baud; variable data structure. A M-bus device is seen as two M-Bus charges by the Master.
Type of cable recommended: telephone cable JYStY N*2*0.8 mm2
11. Security seals
As sealing varies from country to country, local regulations must be followed. To protect the
system against all unauthorised manipulations, the energy meter, the connection screws, the
temperature sensors and the sensor pockets must all be sealed. The seals may only be removed
by authorised persons. In the event of failure to comply with this instruction, the guarantee
obligation will lapse. It is important for the wire seal to be as short as possible so that it is
slightly taut. This is the only way of preventing malicious interference.
