Display
The calculator has a liquid crystal display with 8 digits and special characters. The values that can be shown are
divided into three display loops. All data is retrieved using the push button next to the display.
At the start you are automatically in the main loop (1st level). By pressing the push-button longer than 4 seconds
you change to the next display loop. Keep the push-button pressed until you reach the desired information loop.
By pressing the push-button briefly you can scan all the information within a loop. After 1 minute of non-use of
the push-button, the display automatically returns to the main loop.
Level 1 / Main loop
1) Standard display: total
heat energy; alternating
display: total cooling
energy (for
heating/cooling meter)
2) Segment test, all
segments triggered
simultaneously
3) Heat energy at last
reading date alternating
with last reading date
1
4) Total flow volume [m³]
5) Current power [kW]
6) Current flow [m³/h]
7) Current date
8) Hint flag (alternating
binary and hexadecimal
display)
9) Tariff register 1: values
alternating with tariff
register no. and criteria
2
10) Tariff register 2:
values alternating with
tariff register no. and
criteria
2
11) Momentary reading of
the pulse counter 1
alternating with the pulse
value
2
12) Momentary reading of
the pulse counter 2
alternating with the pulse
value
2
Tariff register and 2 pulse counters are options ex factory.
Level 2 / Technician’s loop
1) Maximum power [kW]
2) Maximum flow [m³/h]
3) Forward flow
temperature [°C]
4) Return flow
temperature [°C]
5) Temperature
difference [
K]
6) Days in operation since
calibration
7) Pulse value
[pulses per litre]
8) M-Bus address
