rules here described is part of the measures for the
safe use of the product and is considered part of the
warranty conditions.
Description
The boiler is heated with photovoltaic electricity. This mode
should be selected if a PV module is connected or if there is an
external energy management system (e.g. solar charge control-
ler with deep discharge protection) that releases the current for
the boiler.
As soon as the battery reaches a voltage of 13.5 V during the
charging process, the excess energy is used to heat up the
boiler.
In addition to the excess control as in mode 2, the water is also
heated to this temperature again as soon as the set minimum
temperature is undershot. (But only until the maximum battery
voltage of 12.4 V is reached.)
As soon as the battery reaches a voltage of 27.0 V during the
charging process, the excess energy is used to heat up the
boiler.
In addition to the excess control as in mode 5, the water is also
heated up to this temperature again as soon as the set mini-
mum temperature is undershot. (But only until the maximum
battery voltage of 24.8 V is reached.)
