22.7 Connection to/via Extension module NFE
Connecting the transmitter and the sensors to an extension module or con-
necting the extension modules to each other is explained in the “Technical
Instructions for Extension module NFE”.
The technical description is shipped with the expansion module and is available for download

23 Controller operation (function additionally bookable as licence)
23.1 General
Special knowledge required
To set the controller function correctly and safely it is essential to have general basic know-
ledge about control technology as well as about parameters and setting procedures used in
the control technology.
To implement volume regulation it is necessary to have a NivuFlow 650 Type TR or TZ trans-
mitter available. Other types are not suitable since they do not have enough inputs and outputs
to drive control slide valves or are not equipped with the corresponding software for controller
functions.
If the Types T2, T4 and TM are still to be used for volume regulation it is necessary to use an
appropriate external controller which then needs to be programmed according to manufacturer
specifications.
