SH Operation
Buffer with solar
Different overviews depending
on configuration
The way the buffer and the temperatures are
displayed on the screen differs depending on the
configuration of the heating system.
Buffer with a solar heating system
If the current
solar panel
temperature is
5°C
(factory setting)
higher than
the
Buffer bottom
solar
temperature, the solar heating system begins
to charge the buffer. The icon for solar charging
appears together with the current solar
panel temperature.
If the
solar panel temperature falls below the
Buffer bottom solar
temperature, the
solar coll-
ector pump is switched off
.

Buffer with solar heating system and stratified
charging valve
The stratified charging valve
toggles solar
charging between the top and bottom sections
of the buffer
. With this function, the temperatures
"Buffer top solar" and "Buffer bottom solar" are
continually compared with the current solar panel
temperature.
First the
top
is always charged as soon as the
solar
panel temperature is higher
than the
Buffer top
solar
temperature.
After reaching the
Buffer target
temperature,
charging switches to
Bottom
until the
Buffer
target
temperature has also been
exceeded
at the
bottom
.
The icon for solar charging
is shown at the
top or in the middle of the buffer, depending on
the position of the stratified charging valve.
