1 General notes
Note:In the text below, the term meter refers both to the heat
meter and to the cooling meter and the combined heat and cooling
meter, unless otherwise specified.
The meter is used as a meter for heating or cooling consumption measure-
ment in systems with water.
The meter consists of a high-tech composite volume measurement unit, two
temperature sensors connected in a fixed position and an electronic unit that
calculates the energy consumption from the volume and temperature differ-
ence.
This technology is thus wear free, robust and largely maintenance free. High
precision and long-term stability guarantee precise and equitable cost ac-
counts.

Safety information 5/26
2 Safety information
The meter may only be used in building service engineering
systems and only for the applications described.
The local regulations (installation etc.) must be adhered to.
The operating conditions according to the type plate must be
complied with during use. Non-compliance can result in hazard-
ous situations and the expiry of all claims arising from liability for
defects as well as liability based on any expressly granted guar-
antees.
Do not under any circumstances carry out welding, drilling or
soldering work close to the meter.
Adhere to the requirements regarding circulating water (CEN /
TR 16911:2016).
The meter is only suitable for circulating water in heating sys-
tems.
The meter is not suitable for drinking water.
Only personnel, trained in the installation and operation of me-
ters in heating and cooling systems, may install and remove the
meter.
Only install or remove the meter when the pipes are pressure-
less.
After installing the meter, check the leak-tightness of the sys-
tem.
Guarantee and calibration validity will lapse if the calibration
relevant security seal is broken.
Only clean the meter from outside with a soft, lightly wetted
cloth. Do not use any spirit or cleaning solvent.
As far as disposal is concerned, the meter is a waste electronic
appliance in the sense of European Directive 2012/19/EU
(WEEE) and it must not be disposed of as domestic waste. The
relevant national, legal regulations must be observed as the
appliance must be disposed of via the channels provided for this
purpose. The local and currently valid legislation must be ob-
served.
The meter contains lithium batteries. Do not dispose of the
meter and the batteries with domestic waste. Observe the local
stipulations and laws on disposal.
You can return the lithium batteries to the manufacturer for
appropriate disposal following use. When shipping please ob-
serve legal regulations, in particular, those governing the label-
ling and packaging of hazardous goods.

Safety information 6/26
Do not open the batteries. Do not bring batteries into contact
with water or expose to temperatures above 80 °C.
The meter does not have any lightning protection. Ensure light-
ning protection via the in-house installation.

Installation 9/26
4 Installation To install the meter proceed as follows:
•Determine the place of installation in line with the inscription on the meter.
Note: For a heating meter the mounting place of the flow sensor
cold side is equivalent to return . The mounting place of the
flow sensor hot side is equivalent to flow .
Note: For a cooling meter the mounting place of the flow sensor
hot side is equivalent to the return . The mounting place of the
flow sensor cold side is equivalent to flow .
•Observe the dimensions of the meter and check whether there is sufficient
space available.
•Rinse the system thoroughly before installing the meter.
•Fit the meter vertically or horizontally between two slide valves so that the
arrow on the housing and the flow direction match. Also observe the instal-
lation situations and the following examples of installation.
Note: Only use the rubber EPDM flat seals that are supplied.
•The meter must not be exposed to tensions or forces caused by pipes or fit-
tings. If this cannot be permanently guaranteed, it is necessary to improve
the point of installation or fix the lines in position, by means of suitable con-
necting brackets for example.
•Fit the temperature sensors in the same circuit as the meter.
•Seal the temperature sensor and the fittings to protect against manipula-
tion.
•If you install the meter for cooling metering, follow the appropriate notes.
Recommendation: If you are installing several meters, the same installation
conditions must be consistent for all meters.
Installation Notes Inlet or outlet sections are not necessary. If you install the meter in the com-
mon return of two circuits, determine a place of installation with a minimum
distance of 10 × DN from the T-piece. This distance ensures a good thorough
mixing of the different water temperatures. You can install the temperature
sensors in T-pieces, ball valves, directly immersed or in pockets depending on
the version. The temperature sensor ends must reach to at least the middle of
the pipe cross section.
Note: Protect the meter against damage through impacts or vibra-
tions at the place of installation.

Installation 10/26
Examples of installation (directly immersed sensor)
You can install the meter in any position e.g. vertically or horizontally. In order
to avoid accumulation of air and disruption in operation, fit the meter in a verti-
cal installation position and not in the uppermost area of a pipeline.
*This position is not permitted for cold
meters and in cases where moisture can
enter the electronic unit due to conden-
sation (e.g. during an interruption in the
summer).

Installation 11/26
Installation notes for sensor adapter set
A mounting set is included for meters with 5.2 × 45 mm temperature sensor.
With this you can fit the temperature sensor directly immersed into an insert or
a ball valve for example.
1. Install with O-ring at the point of installation with the fit-up aid/pen provided.
2. Place both halves of the plastic bolting round the 3 notches of the tempera-
ture sensor.
3. Press the bolting together and screw the bolting hand tight into the point of
installation until it comes to a stop (tightening torque 3 ... 5 Nm).
Fig. 7: Mounting adapter set
Asymmetric mounting (temperature sensor)
The meter can be mounted asymmetric, too. This means one temperature
sensor is directly immersed in the volume measuring tube, whereas the other
temperature sensor is mounted in a protection pocket. For the lower value of
the temperature difference is then 5 K valid at the respective lower flow limit
qi. For this kind of installation the mentioned protection pockets must be used.
Furthermore the national regulations of the respective country have to be ob-
servered.

4.1 Installation for cooling metering and combined heat/cooling meters
Fit the electronic unit separate to the volume measurement unit, e.g. on the
wall for water temperatures below 10° C. Make a loop downwards in order to
prevent condensation running along the connected lines into the electronic
unit. Install the temperature sensors into the pipe from below.
Note: Wall adapter plates are available as an accessory.
