Usage example: You immediately need more hot water
You are in the following situation:
▪
You already consumed most of your domestic hot water.
▪
You cannot wait for the next scheduled action to heat up the domestic hot water
tank.
Then you can activate powerful operation. The domestic hot water tank will start
heating up the water to the Comfort temperature.
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.
About preset values
For some settings in the system, you can define preset values. You only need to set
these values one time, then reuse the values in other screens such as the
scheduling screen. If you later want to change the value, you only have to do it in
one place.

You can set the following user-defined preset values:

Additional to the user-defined preset values, the system also contains some

the DHW tank) if the DHW tank mode is
one of the following:

The software uses this preset value if
the DHW tank mode is

You can use these preset values in
