Terminals (module) 

To connect the external cables to the module, 2-way or 4-way (Phoenix) screw terminals are 
used. Here is an extract from the data sheet: 

Insulation stripping length 

−

 5 

mm 

Connection capacity 

−

  rigid or flexible, 0.2 - 2.5 mm² 

−

  flexible with wire-end ferrule, 0.25 - 1.5 mm² 

−

  conductor sizes 26 - 14 AWG

Test mode 

Test mode can also be called from normal mode by telegram (“heat meter to Pb”). 

 

Test mode 

From here it is possible to call any of the test modes. 
Return to normal mode is performed automatically after no more than 15 hours. 

 

Test mode flowrate 

The flowrate measurements are performed in a measurement timebase of 250ms. Pulses 
proportional to the volume are output via the optical interface. 
The flowrate is – depending on volume measuring unit - displayed with a resolution of e.g. 
0.0001 m³/h (100 ml/h). Each update of the display value is indicated by brief display of an 
arrow symbol on the LCD. 

 

Measured flowrate 

Return to normal mode is performed automatically after no more than 15 hours. 

 

In the 

test mode menu

, it is possible to call the required test mode manually. The display loop 

can be operated with LCD button 1. The required function is called by pressing LCD button 2. 
The values for volume and quantity of heat measured in normal mode remain unchanged. 
While the calibration seal is not set, the required test mode can also be called by telegram via 
the optical interface. 

 

Call 

test mode volume

 

 

Call 

test mode flowrate

 

 

Call 

test mode quantity of heat

 

 

Call 

test mode temperature

 

 

Return to normal mode 

Test mode is ended by pressing LCD button 1. A star symbol (*) now appears in the second 
digit as acknowledgment. When LCD button 1 is pressed again, the next line of the menu is 
shown and it is possible to advance further through the display loop. 
Return to normal mode is performed automatically after no more than 15 hours. 

 

Test mode quantity of heat 

The accumulated quantity of heat is displayed with a resolution of 0.01 kWh. The average of 
640 temperature measurements is evaluated. 
The measurements are ended when the simulated volume of 2 m³ is reached. Then the numeric 
values for the measured quantity of heat and the simulated volume are displayed at appox. 2-
second intervals.
