General notes 4/26
1 General notes
Note:In the following text, the term meter refers to heat meter and
cooling meter, unless they are otherwise differentiated.
The meter is used as a meter for heating or cooling consumption measure-
ment in systems with water.
The meter consists of a volume measurement unit, two fixed temperature sen-
sors and an electronic unit that calculates the energy consumption from the
volume and temperature difference.

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.
Adhere to the operating conditions according to the dial plate
during use. Non-adherence can cause hazards and the guaran-
tee will expire.
The meter is only suitable for circulating water in heating sys-
tems.
The meter is not suitable for drinking water.
Be aware of sharp edges on thread and measuring tube.
The meter is suitable for circulating water in heating systems.
Adhere to the AGFW requirements regarding circulating water
(FW510).
Do not lift the meter by the electronic unit or by the adapter
plate.
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.

Safety information 6/26
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.
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 by the house installation.

Installation 10/26
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 heat meter the mounting place of the cold side is
equivalent to return and the mounting place hot side is equiv-
alent to flow .
Note: For a cooling meter the mounting place of the hot side is
equivalent to return and the mounting place of the 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.
Fit the temperature sensors in the same circuit as the meter.
Observe in addition the admixtures.
Seal the temperature sensor and the fittings to protect against manipula-
tion.
If you install the meter for cooling metering, follow the respective notes.
Recommendation: If you are installing several meters, the same installation
conditions must be consistent for all meters.
Installation notes
Note: Observe the local valid installation instructions mounting the
meter.
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 mechanical
shocks or vibrations at the place of installation.
Note: Ensure the electronic unit is protected against any ingress of
water.

Installation 11/26
Examples of installationYou 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 12/26
Installation notes for sensor adapter set (sensors directly immersed)
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).

4.1 Installation for cooling metering
Observe the following installation instructions to avoid condensation:
Mount the cooling meter so that the black covering on the measuring sec-
tion points sideward or downwards.
Mount the electronic unit separated from the volume measuring unit
e. g. on the wall.
Form with the connected cables a loop downwards.
Mount the protection pocket so that the temperature sensor is oriented ver-
tically downwards or horizontally.
Mount the temperature sensor horizontally or vertically in the pipe from be-
low.
