Application / Function
The heat meter ultego® III eco is a measuring device for the physically correct recording of the heat consumption. It is
subject to mandatory calibration in Germany and many other countries. The device consists of a volumetric flow meter,
two permanently attached temperature sensors and a calculator, which calculates the heat consumption from the volume
and the temperature difference. The volumetric flow meter is a wear-resistant ultrasonic measuring device without me-
chanically moving parts. The long-life battery is designed for the entire duration of the calibration period. The ultego® III
eco cannot be opened without breaking the calibration seal. The heat meter may only be operated under the conditions
stated in the device documentation and the type plate.
EN

Installation notices
Only experts familiar with the associated risks may align, service, repairor exchange parts.
The ultego® III eco left our factory in an impeccable technical state.
Calibration seals of the ultego® III eco may not be damaged or removed! Otherwise the warranty and calibration validity
of the device will be void!
Prior to installing the ultego® III eco, rinse the system thoroughly.
The calculator is attached to an installation base. This is why you must always pick up and transport the heat meter on
the thread connection and never on the calculator.
All lines must be installed at a minimum distance of 300 mm to power or high-frequency cables.
If several meters are installed in a unit, make sure that the installation conditions are the same for all meters.
Cavitation in the entire measuring range must be prevented through overpressure, meaning at least 1 bar to qpand
approx. 2 bar in case of overload qs(applies for approx. 80 °C).
The installation site (backflow/flow) is indicated on the meter face. Please refer to the dimensions and check whether
there is sufficient free space.
If the ultego® III eco is installed in the joint backflow of two heating circuits, e.g. heating and warm water, the installation
site must be at a sufficient distance (at least 10 DN) from the T-piece so that the different temperatures can mix well.
Communication: if the ultego® III eco is equipped with one of the options “M-Bus”, “Minibus” or “Impulse output”, it is sup-
plied with a two-veined connection cable that can be extended with a 2×0.75mm² cable (install distribution box).
Observe the correct polarity when connecting the impulse output (brown +, white –).
Temperature sensor: the cables may not be divided, shortened or extended.

Notices on installation for cold metering
When installing the ultego® III eco for the use as cold meter, make sure that the transducers on the measuring tube
pointto the side or downwards (formation of condensation water).
The measuring tube always has to be installed in the backflow. (Attention! Use flow calculator!)
The calculator must be separated from the flow measurement pipe and installed e.g. on the wall. Here you have to
makesure that no condensation water can run along the connected pipes into the calculator.
Install the volumetric flow meter horizontally or vertically between two shut-offs so that the arrow coincides with the flow-
direction.
The sensors must be installed in the same heating circuit as the volumetric flow meter (observe blending).
The sensors can be installed in T-pieces, ball valves or in immersion sleeves depending on the design (only stilladmis-
sible for old systems acc. to the new MID license).
The immersion sleeves must reach at least up to the middle of the pipe diameter. The exact minimum immersion depth
ofthe sleeve into the flowing medium depends on the approval of the applied temperature sensor.
Temperature sensors and screw fittings have to be sealed to prevent manipulation.
Installation notices for the calculator
The ambient temperature of the calculator may not exceed 55°C.
Avoid direct solar radiation.
Installation is possible horizontally or vertically to the volumetric flow meter. To do so, pull the calculator off the volumet-
ric flow meter, turn it and attach it in the desired position.
With heating water temperatures above 90°C, the calculator must be attached to the wall.
For wall mounting, pull the calculator off the volumetric flow meter, unscrew the attachment base and mount it on the
wall. Slide the calculator back onto the attachment base.
Performing the installation
1
Flush pipeline according to DIN/EN. Observe the country specific regulations!
2
Observe the directional flow comparing it with the arrow on the ultego® III eco.
3
Close the shut-off devices in front and behind the installation site.

Behavior of the meter
If the respective operation margins are exceeded and the flow and temperature difference are positive, the heat quan-
tityand the volume are totaled.
All display segments are activated during the segment test for control purposes.
At the annual target date, the meter counts for the heat and the volume are taken over into last year's memory each
year.
The flow, the heat output and the temperature difference are recorded with the proper prefix. In case the operating mar-
ginis undercut, the device displays u as prefix. The current temperatures are displayed together in °C in a display line
(ininteger numbers).
The 8-digit customer number (secondary address with M-Bus mode) can be set in parameterizing mode. In this case,
thehighest-order digit is not displayed and internally reset to zero.
The operating hours are counted as of the first connection of the supply voltage.
This date is carried forward daily. The meter is always set to Central European Time (CET) by default on delivery.
