Note
■ For system schemes 1 and 2, this
function is only available if option "1"
was selected under "Buffer cylinder
7200".
■ If the value specified here is below the
maximum possible set flow tempera-
ture of one of the connected heating
circuits, this heating circuit may not be
able to be supplied with the calculated
flow temperature when there is a
greater heat demand.

operating status with heating water buf-
fer cylinder (see the operating instruc-
tions for further details regarding the
operating status).
If the long-term average outside temper-
ature exceeds the dual mode tempera-
ture, the control unit block the operation
of the heating water buffer cylinder in
operating mode "Fixed val." (e.g. in
summer). The heating water buffer cyl-
inder will then only be heated to the set
temperature for operating status "Nor-
mal".
If the long-term average outside temper-
ature falls below the dual mode temper-
ature by 0.5 K (hysteresis), operation of
the heating water buffer cylinder in oper-
ating mode "Fixed val." is automatically
continued.
