Setting the time program
Operating status for DHW heating
The different operating statuses indicate
how the DHW cylinder is heated.
"Standard"
The entire volume in the DHW cylinder is
heated to the "Set DHW temperature"
(see page 34).
"Top"
The upper section of the DHW cylinder
is heated to the "Set DHW tempera-
ture" (see page 34), e.g. in the case of
low DHW demand.
Start optimisation
Start optimisation ensures that DHW is
available at the required temperature at
the beginning of a time phase.
Note
This function is only active if a time pro-
gram has been set.

3. "Start optimisation"
Stop optimisation
The stop optimisation ensures that the
DHW cylinder is always fully heated at
the end of the time phase with the oper-
ating status "Standard".
(cont.)
"Temp. 2"
The entire volume in the DHW cylinder is
heated to the "Set DHW temperature
2" (see page 34), e.g. to kill off bacte-
ria.
Example:
From 06:00 h, hot water for showering is
required.
Set the start of the time phase to
06:00 h. With start optimisation, DHW
heating starts automatically earlier than
this.
This makes DHW available at the
required temperature at 06:00 h.
Note
This function is only active if a time pro-
gram has been set.
