INSTALLATION AND OPERATING MANUAL
This system allows all the consumption data of the building to be handled from a single station, thus reducing measure-
ment times whilst protecting user privacy. Transmission frequency is the 868 MHz established by the national radio tran-
smission plan (European standard). The duration and power of the radio signal are irrelevant and are in no way connected
with problems of “electro smog”.
The heat meters of the various user modules transmit consumption via a radio signal and the relative floor aerials (WTT16)
which receive and save the data. Consumption can be read by connecting a Personal computer to any of the floor aerials
via radio or making a cable connection to an aerial with a serial output or using a remote modem (GSM).

During installation, no special start-up procedures are required for radio transmissions as all the system components are
automatically configured for signal transmissions. These characteristics guarantee rapid, problem-free start-up and
simple system management.
Install the Radio system according to the following parameters:

The floor aerials (WTT16) must be fixed to a wall of the stairwell, at a height that prevents tampering, using the supplied
expansion grip.
The Gateway aerial (WTX16.GSM) must be installed in the entrance area of the metered building (this component requires
mains voltage input).
