Describes the general requirements and applies to heat meters.

This European Standard specifies the general requirements and applies to heat meters. Heat meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The meter indicates heat in legal units. Part3 specifies the data exchange between a meter and a readout device (POINT/POINT communication). For these applications using the optical readout head, the EN62056‑21 protocol is recommended. For direct or remote local readout of a single or a few meters via a battery driven readout device, the physical layer of EN13757‑6 (local bus) is recommended. For bigger networks with up to 250 meters, a master unit with AC mains supply according to EN13757‑2 is necessary to control the M-Bus. For these applications the physical and link layer of EN13757‑2 and the application layer of EN13757‑3 is required. For wireless meter communications, EN13757‑4 describes several alternatives of walk/drive-by readout via a mobile station or by using stationary receivers or a network. Both unidirectionally and bidirectionally transmitting meters are supported by this standard.
