Installation
The installation of the meter is carried out by replacing the plastic connection
point in the metering units. No adaptors or other connection components
are necessary. The return temperature probe is integrated into the flow
measurement section. The flow temperature probe must be installed and
welded onto the delivery unit.
For the configuration of the GE552Y017 wireless module, refer to the relative
technical document.
Note.
If installation of the wireless module for energy meters GE552Y017 is
desired, it is recommended that the module mounted on the meter
is configured before installation of the meter itself within the system.
The configuration of the wireless module can only be carried out
when the module is installed on the meter.
