Pulse inputs
Note:
The pulse inputs need to be activated via UltraAssist.
Note:
It is recommended to use the pulse input set T45-PULSE-
IN for the connection.
The meter has 2 pulse inputs enabling the determination in number of external
volume pulses which can be generated, for example, by a cold water meter
and / or a hot water meter.
The pulse inputs can be output via the 868 MHz radio module, the M-Bus
module or the optical interface.
The meter readings of the pulse inputs are also indicated on the LCD.
