INFORMATION
When powerful operation is active, the risk of space
heating/cooling and capacity shortage comfort problems is
significant. In case of frequent domestic hot water
operation, frequent and long space heating/cooling
interruptions will happen.
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.

▪ 30°C~min(50,[6‑0E])°C
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.
