Note: These operating instructions remain with the end user following activation.
Note: In the following text, the term meter refers to both
the heating meter and the cooling meter, unless other-
wise specified.

General
1.1
Use
The T350
(2WR6...)
is used as a meter for heating or cooling
consumption measurement in systems with water.
The meter consists of two temperature sensors and an elec-
tronic unit which calculates the energy consumption from the
volume and temperature difference.
Note: The meter cannot be opened without damaging
the security seal.
1.2
General notes
The meter left the factory in a faultless condition where safety
is concerned. The manufacturer will provide additional tech-
nical support on request. Calibration relevant security seal on
the meter must not be damaged or removed. Otherwise the
guarantee and calibration validity of the meter will lapse.
•
Keep the packaging so that you can transport the meter in
its original packaging following expiry of the calibration va-
lidity.
•
Lay all cables at a minimum distance of 500 mm to high
voltage and high frequency cables.
•
A relative humidity of < 93 % at 25 °C is permissible (with-
out condensation).
•
Avoid cavitation in the whole system due to overpressure
i.e. at least 1 bar at qp and approx. 3 bar at qs (applies for
approx. 80 °C).
•
At 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.
•
At 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.

Safety Information
The meters may only be used in building service
engineering systems and only for the applications
described.
The local regulations (installation etc.) must be ad-
hered to.
Adhere to the operating conditions according to the
dial plate during use. Non-adherence can cause
hazards and the guarantee will lapse.
Adhere to the AGFW requirements regarding circulat-
ing water (FW510).
The meter is only suitable for circulating water in
heating systems.
The meter is not suitable for drinking water.
Do not lift the meter by the electronic unit.
Be aware of sharp edges on the thread, flange and
measuring tube.
Only personnel, trained in the installation and opera-
tion of meters 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 system.
Guarantee and calibration validity will lapse if the
calibration relevant security seals are 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 Di-
rective 2002/96/EC (WEEE) and it must not be dis-
posed 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 observed.
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 manufac-
turer for appropriate disposal following use. When
shipping please observe legal regulations, in particu-
lar, those governing the labelling 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 lightning protection via the in-house installa-
tion.
