Service loop n
LCD button 1 advances the display to the next loop.
After the last loop, the user loop (LOOP 0) appears
again.
LCD button 2 displays the content of the selected
service loop.
Within a loop, the LCD button 2 is used to advance
to the next line of the display. After the last line of
the display, the first display line appears again.
Service loop 1 (“LOOP 1”)
Head of the loop
Current flowrate
Current heat power
Current flow/return temperature
Operating time
Operating time with flowrate
Missing time
Property number, 8-digit
Date
Yearly set day (DD.MM)

Service loop 2 (“LOOP 2”)
In service loop 2, the
maxima
are displayed. LCD
button 2 calls the displays one after the other.
Head of the loop
Max. flowrate,
at 2s intervals with date stamp
Max. power,

Max. temperatures,
at 2s intervals with date stamp
for flow and return maximum
Measuring period for maximum calculation
Service loop 3 (“LOOP 3”)
Service loop 3 shows the
monthly values
. LCD
button 1 is used to select a month out of the 18
previous months. The data for that month are then
opened with LCD button 2. Each further press of
LCD button 2 shows the next value for the selected
month.

Quantity of heat on the set day
Tariff register 1 on the set day
Volume on the set day
Max. flowrate on the set day,
at 2s intervals with date stamp
Max. heat power on the set day,
at 2s intervals with date stamp
Max. temperatures on the set day,
at 2s intervals with date stamp
for flow and return maximum
Missing time count on the set day
After the last display, the previously selected set day
is displayed again. Pressing LCD button 1 selects
the next set day.
Note: If you want to drop out and go directly to the next loop,
choose a monthly value by pressing LCD button 2 and then press
LCD button 1.
Service loop 4 (“LOOP 4”)
Service loop 4 shows the
unit parameters
. LCD
button 2 calls the displays one after the other.
Head of the loop

Previous year’s values
The electronic unit stores the current meter readings
for quantity of heat, volume, the tariff register,
missing time, and flowrate measuring time as well as
the service life maxima for flowrate, power,
temperature difference, flow temperature, and return
temperature with their date stamps on a yearly set
day.
Monthly values
The electronic unit stores the meter readings for
quantity of heat, volume, the tariff register, missing
time, and flowrate measuring time as well as the
monthly maxima for flowrate, power, temperature
difference, flow temperature and return temperature
with their date stamp for 18 months on the set day of
each month.
Note: The standard time used is Central European
Time (CET). If daylight-saving time is activated,
storage will be performed accordingly.
The monthly values can also be read out via the
optical and the 20 mA interface.
