ultego® III perfect
Functional details
If the response thresholds are exceeded and the flowrate and temperature difference are positive, the quantity of thermal
energy and the volume are summated. In the segment test, all segments of the display are switched on for test purposes.
On the yearly set day, the meter readings for quantity of heat and volume, the values for the service life maxima and the
flowrate and missing times are placed in the previous year memory.
The flowrate, heat power, and temperature difference are acquired with the correct sign. If the response threshold is not rea-
ched, the value is preceded by a u. The current temperatures are shown together on one line of the display as integers in °C.
To calculate the maximum, the heat power and flowrate are averaged over a measuring period of, for example, 60 min. The
maximum values from the average calculation are preceded by Ma on the LC display.
The 8-digit property number (also the secondary address in M-bus operation), can be set in parameter setting mode. The unit
number is assigned by the manufacturer.
The operating time is counted from the first time the power supply is connected. Missing times are summated, if an error is
pending that prevents the heat meter from measuring. The date is incremented daily.
The type of installed modules is displayed. If an M-but module is installed, the primary and secondary address will be dis-
played on the following lines.
The number for the firmware version is assigned by the manufacturer.
Notes
Regulations on the use of heat meters must be observed, see EN 1434, Part 6!
In particular, cavitation in the system must be avoided.
Heat meters up to DN25 may only be installed with directly immersed sensors according to German calibration law!
Install the unit in such a way that no water can enter the electronic unit during operation.
All information given on the data sheet of the heat meter must be observed.
User seals may only be removed by authorized persons for service purposes and must be replaced afterwards.
No later than 30 seconds after installation, the heat meter detects the plugged modules automatically and is ready for
communication or pulse output.
The type of modules plugged can be displayed in the service loop depending on how the display is parameterized.
For fast pulses, the parameters must be set accordingly with the PappaWin software.
