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.

the tank temperature rises above this value, domestic hot water preparation and
space heating/cooling are executed sequentially.
