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
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).

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.
