Operational details

.  

If the response limits are exceeded and the flow rate 
and temperature difference are positive, the 

quantity of heat 

and the 

volume 

are summated. 

With the 

segment test, 

all segments of the display 

are activated to test the display itself. 

On the 

yearly

 

set day

 the meter readings for the 

quantity of heat and volume are placed in a 

previous year's memory

 identified with a 

V. 

 

*) With firmware versions 2.12 and 2.13 this function 
is not possible together with fast pulses! The display 
of S 00,01,-- means that the yearly set day is 
deactivated). 

The 

flow rate, 

the 

heat output

, and the

 differential 

(temperature difference) are acquired with the 
correct sign. If the lower response limit is violated, a 

u

 is displayed in front of the value. The current 

temperatures 

are displayed as integer values in °C 

together on one display line. 

The heat output and flow rateare averaged over the 

measuring period

 of, say, 60 min. The 

maximum 

values

 of mean value calculation are marked with 

an 

M

 in the leading position. 

The 8-digit 

property number

 (secondary address 

for M bus operation) can be set in parameterisation 
mode. The most significant position is suppressed in 
the display. The 

unit number 

is assigned by the 

manufacturer. 

The 

time of operation 

is counted from initial 

connection of the power supply. 

Time of downtime 

is summated if a fault prevents the heat meter from 
measuring. The 

date

 is incremented every day. 

The 

module type

 is displayed. If an M bus module 

is installed, the primary address is displayed on the 
next line. A modem, analog modul or radio modul is 
also displayed as M bus module. 

The number of the 

firmware version

 is assigned by 

the manufacturer. 

 

Additional 

The calculator may only be cleaned from the 
outside. Use only a soft and wet cloth without any 
aggressive detergent.
