NOTICE
An external antenna is required for RF module T45-RADIO-EXT with an SMA connection,
e.g. WZU-ANT-MAG or WZU-ANT-WALL.
The RF intelligence resides in the meter, the module is only responsible for communications.
The RF meters are set by default to 'stationary'.
Data output conforming to OMS
The following data is available:
Stationary read out (F000)
Transmission interval 15 min
● Current energy
● Current volume
● Current power
● Current flow rate
● Current temperatures heat and cold side
● Error (manufacturer-specific)
● Current time stamp (type I)
Mobile read out (F001)
Transmission interval 30 s
● Current energy amount
● Current volume
● Prev. month value energy
● Prev. month value volume
● Save time last previous month
● Prev. year value energy
● Save day last previous year
● Error flags
● Meter time
Other data telegrams on request.
The applicable read out type must be indicated when ordering the RF module (stationary,
mobile).
Pulse inputs
Pulse input set T45-PULSE
Function description
The meter has two pulse inputs to count external volume pulses, e.g. as generated from a
chilled water meter and/or hot water meter.
Pulse inputs can be supplied via various communication modules and optical interfaces.
Meter readings of the pulse inputs can also be displayed on the LCD.
The pulse inputs must be activated by the service software.
