Start Optimisation; A Stop Optimisation - Viessmann VITOCAL WPR 300 Service Instructions Manual

DHW control settings

6009 Start optimisation

Comfort function for DHW cylinder heating.
The start optimisation ensures that
DHW is already available at the
required temperature at the beginning
of DHW heating in accordance with
the set switching times. For this, DHW
heating begins accordingly before the
set switching time. The control unit
calculates this time point for the start
of DHW heating from the differential
between the set and actual cylinder
temperatures, and parameter "T rise /
hour" (600D).
"Yes" Start optimisation is on.
"No" Start optimisation is off.

600A Stop optimisation

Comfort function for DHW cylinder heating.
The stop optimisation ensures that
the DHW cylinder is always fully
heated at the end of the start time for
DHW heating. Cylinder heating
begins accordingly before the set end
of DHW heating. The control unit cal-
culates the time point for the start
from the differential between the set
and actual cylinder temperatures, and
parameter "T rise / hour" (600D).
"Yes" Stop optimisation is on.
"No" Stop optimisation is off.

Note
If a second, lower temperature sensor
is installed in the DHW cylinder, heat-
ing with start optimisation is started
and stopped via this sensor.
