The tank type is displayed, but cannot be adjusted.
Emergency
When the heat pump fails to operate, the booster heater can serve
as an emergency heater. It then takes over the heat load either
automatically or by manual interaction.
▪ When
Emergency
is set to
Automatic
and a heat pump failure
occurs, the booster heater in the tank automatically takes over the
domestic hot water production.
▪ When
Emergency
is set to
Manual
and a heat pump failure
occurs, the domestic hot water heating stops.
To manually recover it via the user interface, go to the
Malfunctioning
main menu screen and confirm whether the
booster heater can take over the heat load or not.
To keep energy consumption low, we recommend to set
Emergency
to
Manual
if the house is unattended for longer periods.

INFORMATION
The auto emergency setting can be set in the menu
structure of the user interface only.
Booster heater capacity
The capacity of the booster heater must be set for the power
consumption control feature to work properly. When measuring the
resistance value of the booster heater, you can set the exact heater
capacity and this will lead to more accurate energy data (e.g. for
Power consumption control). The capacity of the booster heater
installed in the domestic hot water tank is 1,2 kW.

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.

only
: Only reheat
operation is allowed.
▪ 1:
Sc reheat
: The domestic
hot water tank is heated according to a
schedule and between the scheduled
heat up cycles, reheat operation is
allowed.
▪ 2:
Schedule only
: The domestic hot
water tank can ONLY be heated
according to a schedule.
See the operation manual for more details.
Settings for Reheat only mode
During Reheat only mode, the tank setpoint can be set on the user
interface. The maximum allowed temperature is determined by the
following setting:

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.

Desired reheat tank temperature
, used in
