Operating instructions
These operating instructions have to be handed over to the end user
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.
