Detailed screen with weather-dependent
curve
When weather-dependent (WD) operation is active the desired
leaving water or tank temperature is determined automatically
depending on the averaged outdoor temperature. When the outdoor
temperature is lower the leaving water or tank temperature will need
to be higher as the water pipes will be colder and vice versa.
2-points WD curve
The weather-dependent curve is defined by two setpoints:
▪ Setpoint (X1, Y2)
▪ Setpoint (X2, Y1)

>
Reheat only
.
Comfort setpoint
Only applicable when domestic hot water preparation is
Schedule
only
or
Sc reheat
. When programming the schedule, you
can make use of the comfort setpoint as a preset value. When you
later want to change the storage setpoint, you only have to do it in
one place.
The tank will heat up until the
storage comfort temperature
has
been reached. It is the higher desired temperature when a storage
comfort action is scheduled.
Additionally, a storage stop can be programmed. This feature puts a
stop to tank heating even if the setpoint has NOT been reached.
Only program a storage stop when tank heating is absolutely
undesirable.
