3.2 Function
Using bare wire heating in the unit's heating block,
drinking water is heated and can then be drawn from
one or more points. The electronics measure the tem-
perature of the cold water supply and the water volume
flow. The electrical performance required to heat the
water to the required temperature is calculated using
these two values. The unit's display temperature can be
changed in increments of 0.5 °C. The volume and heat of
the hot water is dependent on the electronicVED plus
performance category and settings. The output of each
VED unit is listed in section 11. In addition, the water and
energy consumption data can be linked to the perform-
ance data via the display. This means that the
electronicVED plus can be configured in such a way that
both the current and cumulative energy consumption
can be displayed and called up. The built-in Memo func-
tion allows 4 fixed temperatures to be saved and these
can be called up by pressing a button.
