INFORMATION
To make tank defrost possible, we recommend a minimum
tank temperature of 35°C.
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.

Heat up mode:
▪ 0:
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
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:

Maximum:
[5.8]
[6-0E]
The maximum temperature that users
can select for the domestic hot water.
You can use this setting to limit the
temperature at the hot water taps.
The maximum temperature is NOT
applicable during disinfection function.

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.

Reheat setpoint
Desired reheat tank temperature, used:
▪ in Schedule
+
reheat mode, during reheat mode: the
guaranteed minimum tank temperature is set by the Reheat
setpoint minus the reheat hysteresis. If the tank temperature
drops below this value, the tank is heated up.
▪ during storage comfort, to prioritize the domestic hot water
preparation. When the tank temperature rises above this value,
domestic hot water preparation and space heating/cooling are
executed sequentially.

Hysteresis (reheat hysteresis)
Applicable when domestic hot water preparation is scheduled
