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

Configuration wizard: Tank

This part only applies to systems with an optional domestic hot water
tank installed.
Heat up mode
The domestic hot water can be prepared in 3 different ways. They
differ from each other by the way the desired tank temperature is set
and how the unit acts upon it.
# Code
[5.6] [6-0D] Heat up mode
▪ 0: Reheat only: Only reheat operation
is allowed.
▪ 1: Schedule + reheat: The domestic
hot water tank is heated according to a
schedule and between the scheduled
heat up cycles, reheat operation is

See the operation manual for more details.
INFORMATION
Risk of space heating capacity shortage for domestic hot
water tank without internal booster heater: In case of
frequent domestic hot water operation, frequent and long
space heating/cooling interruption will happen when
selecting the following:
Tank > Heat up mode > Reheat only.
Comfort setpoint
Only applicable when domestic hot water preparation is Schedule
only or Schedule + 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.
