Electronic cost allocator
EG RADIO electronic cost allocator is equipped with a radio interface. Parameters (time, cycles, S1 or T1 modes, AES-128 cryptography) can be configured through an optical interface by using the dedicated software. Standard configuration is as follows: T1 mode, AES-128 cryptography set but not active, data sending every 120 seconds, from 7 a.m. to 7 p.m., 5 days out of 7 (weekend excluded), 12 months, long telegram (current and historical data), yearly billing date (31/05).
|Approved to standard EN 834|
|Equipped with 2 temperature sensors|
|868 MHz Wireless M-BUS radio system|
|Approved to EN 13757-4. Thanks to this standard protocol it can be used with different radio receivers|
|Fixed or variable scale modes (a large library of WTP-Berlin Kc1-2 correction factors is available)|
|Optical interface for parameters configuration and data download|
|AES-128 cryptography for a protected data sending (can be activated)|
|Protection against tampering and external heating sources|
|Meter reading can be stopped in summertime|
|Over 10 years maintenance-free operation|
|Control number to check validity of meter reading|
|Wide range of fixing accessories|
EG RADIO cost allocator is equipped with an optical interface for data configuration and reading. Data can be acquired through an infrared optical head by using the dedicated software. Interface remains active for 15 seconds after it has been selected.
Remote sensor can be supplied upon request. Radiator sensor functions therefore as remote sensor (cable length: 2 m) and is mounted on the radiator.
Cost allocator can be installed close to the radiator. Its 7 and a half digit liquid crystal display is not active when instrument is on. Press selection key to activate display in order to read a value or to use the interface. Display switches off automatically after 30 seconds the selection key is unpressed.
EG RADIO cost allocator monitors the main functions in order to guarantee a proper working and promptly report eventual anomalies.
Control number is calculated through an algorithm which is unknown to user and it is then shown on the display. In this way both consumption and error bit are encrypted. This function allows to detect eventual removal of cost allocator from radiator.
