5.1 [BufferFlex] function block
The setting parameters for the buffer are
dependent on the boiler
If the buffer is connected to a boiler with an
independent fuel conveying system (automatic boilers
such as the PelletsUnit, PelletsCompact, HACK, PE-
K), it is also possible to set minimum temperatures for
the buffer.
If the buffer is connected to a log boiler (manual
heating), fewer settings are possible. That is why the
following setting parameters are separated by boiler.
5.1.1 PufferFlex for automatic boilers
5.1.1.1 Basic settings
Basic PufferFlex settings
For the basic function of the buffer, the respective
temperature sensors must be assigned in the buffer
settings.Some of the following parameters can also be
found in the settings of the PufferFlex [Sensor assign-
ments].
Set or check the following parameters.
Explanation of [Total volume]
The whole buffer volume needs to be indicated for this
parameter. This enables the control system to optimise
the charging of the buffer.
