1.3 Radio interface wireless M-Bus EN 13757-3, -4 (optional)
The radio interface is for the transmission of meter data (absolute values).
General information about the radio interface:
Installation of radio components between or behind heating pipes, or the presence of other
bulky metallic obstacles directly over or in front of the housing must be avoided.
The transmission quality (range, telegram processing) of radio components can be negatively
influenced by instruments or equipment with electromagnetic emissions, such as telephones
(particularly LTE mobile radio standard), wi-fi routers, baby monitors, remote control units,
electric motors, etc.
In addition, the construction of the building has a strong influence on the transmission range
and coverage. Furthermore, when using installation boxes (substations) they must be
equipped with non-metallic covers or doors.
The factory-setting of the clock in the meter is standard (winter) Central European Time (GMT +1). There is no automatic
changeover to daylight savings (summer) time.
The radio function is deactivated upon delivery (factory-setting). See section "Activation of the radio interface".
