IMPORTANT BEFORE INSTALLATION
Hot water networks operate at high temperatures and high pressures, which
can cause serious bodily injury if handled improperly. Therefore the measuring
devices may only be installed by qualified and trained personnel. The pipes must
be earthed. The installation of a heat meter must be carried out in accordance
with the recognised technical regulations (e.g. EN 1434-6) in such a way that
a correct measurement value can be recorded. The reading must be possible
without any additional aids, and trouble-free deinstallation of the individual com-
ponents must be possible after the validity of the calibration has expired! Small calculator unit
Big calculator unit
IN ADDITION, THE FOLLOWING MUST BE OBSERVED
• Permissible ambient temperature (from 5° C to 55° C)
• Sealing the flow sensor itself and the temperature sensor is important and prevents
unauthorised deinstallation.
• Flush the pipe system thoroughly before installing the flow sensor.
• According to EN 1434-6, the calculator/flow sensor/signal cables (e.g. sensor
cables) must not be installed/routed near live mains cables and/or sources of
electromagnetic interference (min. 50 mm distance).
• Caution: Special care is required in the case of particularly strong sources of
electromagnetic interference, e.g. machines, frequency converters, power inverters,
circuit breakers, high-voltage pumps and neon tubes, and the distance to the signal
cables of the heat meter must be increased to 50 cm.
• ESD compliant installation for external cables according to EN 61340-5.
• Environmental class C according to EN 1434-1 as well as E1 and M1 according
to directive 2014/32/EU.
• The flow sensor must never be lifted or transported using the connection cable!
• Do not route cables along hot pipes.
• Big arithmetic unit
• The heat meter has protection class IP54 as standard. In the model with the large casing, the heat meter has protection
class IP20 in the area of the connection terminals.
• Opening a security seal will result in loss of the compliance and guarantee.
• Cleaning the casing must only be carried out from the outside with a soft, slightly moistened cloth - do not use cleaning
agents.
• Do not carry out welding anywhere near the meter.
• The meter should remain in the original packaging until all connection, insulation, painting and flushing work is completed.
• Always install the meter according to the mounting position printed on the serial plate (supply or return).
• The flow sensor can be installed either horizontally or vertically in any mounting position.
• The heat meter must be protected against damage caused by shocks or vibrations that may occur in the installation
location. During commissioning, the shut-off valves must be opened slowly.
• Threaded connections on the meter must correspond with the respective counterparts of the pipe in nominal diameter
DN and nominal pressure PN (according to EN 1092). Do not expose the meter to excessive stresses caused by pipes
or fittings. The pipes of the heating system must be sufficiently anchored in front of and behind the heat meter. All
screws, nuts and seals used must be designed for the rated values DN, pressure rating PN, maximum temperature and
maximum permitted pressure.
INSTALLATION NOTE
The use of the heat meter temperature sensor is only permitted in conjunction with corresponding temperature sensor mea-
suring points approved for the sensor. Both measuring points of a heat meter must be designed in the same way.
A combination of immersion sleeve and direct measurement is forbidden.

OPTION MAXIMUM VALUES
These optional displays show the current monthly
maximum values for power (3.11), flow rate (3.12) and
supply temperature (3.13) with time stamp. 18 maximum
monthly values are stored internally for each item, which
can be read out via M-Bus, optical interface or the LCD
display at the key date level (2.X.8 / 2.X.9 / 2.X.10). The
period duration for determining the maximum values
is 60 minutes. The period duration can be varied via
M-Bus or the optical interface with the help of the service
software, in a range from 1 min - 1440 min (= 1 day).
OPTION TARIFF FUNCTION
(NOT AVAILABLE FOR COMBI METERS)
With the optional tariff function, the values for energy
(1.12 / 1.14) and volume (1.13 / 1.14) are shown in ad-
ditional displays, under previously defined operating
conditions. These operating conditions can be defined
via one of the following parameters:
- Temperature difference - Flow rate
- Supply temperature - Power
- Return temperature - Time window
These parameters are programmed in the factory, and
can be changed by authorised service personnel using
the service software via M-Bus or optical interface, if
the displays are not marked with the § symbol. It is not
possible to adjust the parameters using the buttons on
the UltraMaXX.

OPTION DATA LOGGER
The UltraMaXX offers the option of saving predetermined
parameters at a fixed time interval via 4 parallel data reg-
isters. These saved values can be read out by authorised
service personnel using the service software via the M-Bus
option or via the optical interface. It is not possible to display
the values via the LCD display.
Annual logger
For 16 years, up to 6 parameters are stored once a year at
24:00 on a defined day.
Monthly logger
For 48 months, up to 6 parameters are stored at 24:00 on
the last day of the month.
Daily logger
For 460 days, up to 6 parameters are stored daily at 24:00.
Programmable logger
Up to 6 parameters are stored for 1500 steps, with a
programmable time ranging from 1 minute up to 7 days.
The time and the internal error messages are also saved
for all loggers. If the maximum number of stored values of
a logger is reached, the oldest value is discarded and the
new value is stored (rolling circulation) for each subsequent
scheduled storage.
