10.5 USB Plug-In Module (for M-Bus slot) 

 
Order number: 68504688 
Using this plug-in module, the calculator unit can 
be connected to a PC / Notebook or hand-held 
computer with USB input. If an M-Bus plug-in 
module is installed, this must be removed 
beforehand. A driver is required for connection, 
which is also supplied with a data carrier. The 
description of the driver installation is given there. 
 

10.6 LONWORKS

®

-FTT10A 

 
Using this plug-in module, the meter can be 
connected via a LONTALK

®

 protocol to 

appropriate instrumentation. A driver software is 
supplied on a mini-CD. For more detailed 
information, refer to Datasheet LH 6132 DE.  
 

10.7 Inserting the Plug-In Modules into the 
Calculator Unit 

 
In each calculator unit has a slot for the M-Bus 
modules (at the back, right) and the telecounting 
modules (at the front, left). 

The approved 

modules for the calculator unit must only be 
installed into the slots provided for them.

  

 
 
Figure 16: Installation of the plug-in modules 

 

 
During assembly, insert the plug-in modules into 
the left and right guide made from white plastic 
(Figure 16). 
The contact pins must not be bent and easily glide 
in the contact bushes provided for them. 
Guide the connecting cable through the hole in 
the moulded rubber part and establish strain relief 
using a cable-tie. Now connect the wires to the 
appropriate terminals and replace the moulded 
rubber part. 
 

10.8 Combined Heat / Cooling Meter (Order 
Option) 

 
Designation: 
PolluTherm H or PolluTherm X H 
 
With this option, the PolluTherm switches 
between metering of the heating and cooling 

energy with the aid of an automatic switching 
point. The factory setting for switching to cooling 
metering is: 
 

Flow temperature 

 25 °C 

and

 

Negative temperature differential 

 - 0.15 K 

 
To switch back to warm metering, the following 
applies: 
 

Flow temperature > 25 °C 

and

 

Positive temperature differential 

 0.15 K 

 
As required, this switching point can be adapted 
on site, using the service software MiniCom, from 
Version 3.6.0.65. 
 
 

10.9 Optional Integrated Data Logger (Order 
Option) 

 
If the option is installed, the housing cover has the 
additional inscription "Data Logger". 
The integrated data logger saves consumption 
values at a time interval and actual values   
(energy, flow, temperatures) that can be selected 
(3 to 1440 minutes). The logger data can be read 
out through the optical interface, M-Bus using the 
service software MiniCom, from Version 3.6.0.65. 
The time setting (factory setting: 60 minutes) can 
also be changed using the MiniCom, from Version 
3.6.0.65. 
 
For connection to a PC, either an optical data 
coupler (refer to Section 10.1.) or a USB plug-in 
module can be used. 
 

10.10 Conversion of Battery Device to Power 

Supply Device 

 
Before converting, observe the following and also 
carry out in this sequence: 

  Before the supply battery is removed, the 

calculator module must be removed from the 
calculator unit. For this, open the cover of the 
calculator unit and remove the right retaining 
screw (screwdriver: Torx 6) under the plastic 
cover (user seal, refer to Figure 17). 

  Subsequently, carefully pull the calculator 

unit module upwards, out of the plug-in 
connection. The left and middle seal must not 
be removed (loss of calibration)! 

  Insert the backup battery AA 3,6V 

(68504998) into the rear of the calculator unit 
module. The battery is required to secure the 
date and for temporary operation when the 
mains power is interrupted. 

 

Remove the main battery (D-cell) and insert 
the mains module.
