Introduction
The ULTRAHEAT®XS heat meter is a measuring instrument for
physically correct recording of heat 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 calcu-
lates the heat consumption from the volume flow and temperature
difference.
The volume measuring unit is a non-wearing ultrasonic measuring
device without mechanically moving parts. The long-life battery is
designed for the calibration validity period. ULTRAHEAT®XS
cannot be opened without breaking the calibration seal.
The heat meter must only be operated under the conditions stated
in the device sheet and on the rating plate.
Information on the Display
The displays of the heat 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
- Heat (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 heat meter constantly performs self-diagnosis and can dis-
play various faults.

If the response thresholds are exceeded and the flowrate and
temperature are positive, the heat 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 heat quantity, vol-
ume, and missing time are placed in a previous year memory
each year.
The flowrate, heat power, and temperature difference are re-
corded signed. Values below the response threshold are pre-
ceded by a "u". The current temperatures are displayed together
as integer °C values on one display line.
The 8-digit customer number (secondary address for M-bus op-
eration) can be set in parameterization mode. The most signifi-
cant digit is suppressed on the display. The device number is
assigned 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 heat meter from measuring. The date is incre-
mented 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. Dispose of used batteries
at suitable collection centers.
The transport of the heat meter is permitted only in the original
package. If the meter needs to be sent by air freight then the
battery must be removed prior to shipping!
