Operating Instructions
Note: These operating instructions remain with the end user following installation.
Note: In the following text, the term meter refers to
both the heat meter, the cooling meter and the flow
meter, unless they are otherwise differentiated.
1.
General
1.1
Use
The UH50.. is used as a meter for heating or cooling consump-
tion measurement in systems with water.
The meter consists of two temperature sensors and an elec-
tronic unit that calculates the energy consumption from the
volume and temperature difference.
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 seals 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 (without
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
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
sensor hot side is equivalent to the return
mounting place of the flow sensor cold side is equivalent to
flow
.

Safety Information
The meter may only be used in building service engi-
neering systems and only for the applications de-
scribed.
The meter is designed in accordance with the guide-
lines of the environment categories M1+E1 and must
be fitted in line with these regulations.
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 haz-
ards and the guarantee will lapse.

Adhere to the AGFW requirements regarding circulat-
ing water (FW510).
The meter is only suitable for circulating water in heat-
ing systems.
The meter is not suitable for drinking water.
Do not lift the meter by the electronic unit.
Be aware of sharp points on the edges, 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.
The 110 V / 230 V connections may only be made by
an electrician.
The meter may only be powered up once the installa-
tion has been completed. There is otherwise a danger
of electronic shock on the terminals.
A defective or obviously damaged appliance must be
disconnected from the power supply immediately and
replaced.
As far as disposal is concerned, the meter is a waste
electronic appliance in the sense of European Di-
rective 2012/19/EU (WEEE) and it must not be dis-
posed of as domestic waste.
-
Dispose of the meter through the channels pro-
vided for this purpose.
-
Respect the local and currently valid legislation.
-
Dispose of used batteries at the collection points
provided for them.
The meter contains lithium batteries. Do not dispose of
the meter and the batteries with domestic waste. Ob-
serve the local stipulations and laws on disposal.
You can return the lithium batteries to the manufactur-
er for appropriate disposal following use. When ship-
ping please observe legal regulations, in particular,
those governing the labelling and packaging of haz-
ardous 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.
