Static Meter 2WR6 / XS Subject to change without prior notice UH 304 –101u1/2
Note: In the following text the term Meter covers the
Heat Meter as well as the Cold Meter if not men-
tioned otherwise.
Introduction
The static meter 2WR6 / XS is a measuring instrument for physi-
cally correct recording of energy consumption. It is required to be
certified by law in Germany and many other countries. The device
consists of a volume measuring unit, two permanently connected
temperature sensors, and an electronic unit that calculates the
energy consumption from the volume flow and temperature dif-
ference.
The volume measuring unit is a non-wearing ultrasonic measur-
ing device without mechanically moving parts. The long-life bat-
tery is designed for the calibration validity period. The meter
cannot be opened without breaking the security seal.
The meter must only be operated under the conditions stated in
the manuals and on the dial plate.
Information on the Display
The displays of the meter are structured on several levels and
may deviate from the standard described here. Each short press
of the button switches to the next display of the user loop (level
1).

Monthly Values
The calculator stores the following values for 15 months at each
end of month
- Energy (meter reading)
- Volume (meter reading)
- Missing hours (meter reading)
From the month set day display, press the service button for 3s to
enter the previous month's values.
The month values can also be read out via the optical interface.
Fault Codes and IDs
The meter constantly performs self-diagnosis and can display
various faults.

If the response thresholds are exceeded and the flowrate and
temperature are positive, the energy quantity and volume will be
summated. The segment test displays all display segments for
test purposes.
On the yearly set day, the meter readings for energy quantity,
volume, and missing time are placed in a previous year memory
each year.
The flowrate, power, and temperature difference are recorded
signed. Values below the response threshold are preceded by a
"u". The current temperatures are displayed together as integer
°C values on one display line.
The 8-digit property number (secondary address for M-bus opera-
tion) can be set in parameterization mode. The most significant
digit is suppressed on the display. The device number is as-
signed by the manufacturer.
The operating hours are counted from initial connection of the
power source. Missing hours are summated if a fault is pending
that prevents the meter from measuring. The date is incremented
daily.
The firmware version number is assigned by the manufacturer.

Notes:
Observe national calibration laws when replacing the battery.
Batteries must not be opened, come into contact with water, or
be exposed to temperatures above 80 °C. The meter contains
Lithium batteries, so it is not allowed to dispose it wih the house-
hold waste. Return of the Lithium batteries must be carried out
professionally. It is possible to return the product after use for
proper disposal to the manunfacturer. Please follow the legal
regulations at the shipment of Lithium batteries, which rules
amongst others the declaration and the packaging of hazardous
good.
