Note
In mode 3 two measuring electrodes NRG 6-9 (one for banking-up of condensate and
one for steam loss) per measuring channel are connected together so that e. g. a float trap
can be monitored. For more information see the installation instructions for NRG 6-9,
NRG 6-7, NRG 6-8.
In mode 6 and 7 the measuring electrodes NRG 6-7, NRG 6-8 receive the measure-
ments of the condensate temperature only from the integrated temperature sensor.
