Operating Instructions

1 General
Note
These operating instructions remain with the end user
after commissioning.
Note
In the following text, the term "meter" is used to refer
to both the heating meter as well as the cooling meter
unless otherwise stated.
1.1 Use
The meter is used to measure the heat or cold consumed in
heating/cooling systems.
The meter consists of two temperature sensors and a
calculator, which calculates the energy consumption based
on the volume and temperature difference.

1.2 General information

The meter has left the factory in a technically safe condition.
Further technical support is provided by the manufacturer on
request. The meter's calibration-relevant security symbols
must not be damaged or removed. Otherwise, the warranty
and calibration validity of the meter will be invalidated.
• Keep the packaging in a safe place so that you can
transport the meter in its original packaging after the
calibration validity has expired.
• Lay all cables at a minimum distance of 500 mm from
power and high-frequency cables.
• A relative humidity of < 93 % at 25°C is permissible
(non-condensing).
• Avoid overpressure cavitation throughout the system,
i.e. at least 1 bar for qp and approx. 3 bar for qs
(applies for approx. 80 °C).
• The control line must not be cut, shortened or
extended.
• In the case of a heat meter or combined heat/cooling
meter, the cold side installation location
corresponds to the return
installation location corresponds to the supply
• In the case of a cooling meter
installation location corresponds to the return
the cold side installation location to the supply

(CEN / TR 16911:2016).
Caution
The meter is only suitable for circulation water in
heating systems.
Caution
The meter is not suitable for drinking water.
Caution
Do not lift the metre on the calculator.
Caution
Pay attention to sharp edges on threads, flanges and
the measuring tube.
Caution
Only personnel trained in the installation and operation
of meters in heating/cooling systems may install and
remove the meter.
Caution
Only install or remove the meter on an unpressurised
system.
Caution
After installing the meter, check the leak tightness of
the system.
Caution
Breaking the safety marks relevant for calibration
voids the warranty and the validity of the calibration.
