Wireless meters
ACT50 is used to configure the wireless modules.
Wireless operation is activated via the WFZ-PS radio telegram tool or the ACT50 software.
Wired meters
Since the M-bus module adopts all parameters from the meter, only the primary address can
be configured via the M-bus system.
The power required for operation is supplied by the M-bus system, but the module is
equipped with a battery. It powers the module when there is no power available from the M-
bus.
The modules do not affect the acquisition of consumption data and, for this reason, can be
retrofitted at any time without damaging the seal.
Sealing
After mounting the meter, all components must be sealed to prevent tampering (observe
national regulations):
● The flow measuring section with its fitting (inlet)
● The flow temperature sensor with the ball valve or the immersion pocket, the immersion
pocket with the pipe and, if required,
● The module with the processor
