Simplified readout of the unit
In this section is described the simplified readout of all the metering parameters for normal use.
The decimals in the readouts are after the point: to indicate them more clearly, the standards require that
the decimal figures are clearly distinct from the whole numbers; for this reason the decimal figures are
highlighted by dashes
.
The “v” indices are placed automatically above the diagrams which indicate by means of symbols tne significance
First page which always appears on the meter when the power is switched on; when the power is
switched off, the page appears by pressing
.
The metering in MWh (aligned if necessary) summed by heating (calories); if the symbol appears alter-
nating with ALA, this means that there is an alarm status the type of which will be explained later.
Press
This is the metering in MWh (aligned if necessary) summed by conditioning (frigories), if programmed,
otherwise this page is skipped.
