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

domestic hot water temperature depends on this setpoint as well as the actual
storage tank temperature. For more information about how to do this, see
"10.3.5 Setpoint screen" [

To activate powerful operation
Activate or deactivate Powerful operation as follows:
1 Go to [5.1]: Tank > Powerful operation
2 Turn powerful operation Off or On.
Usage example: You immediately need more hot water
If you are in the following situation:

▪ You cannot wait for the next scheduled action to heat up the storage tank.
Then you can activate DHW powerful operation.
Advantage: The storage tank is immediately heated up to the tank temperature
setpoint.
INFORMATION
When powerful operation is active, the risk of space heating/cooling and capacity

operation, frequent and long space heating/cooling interruptions will happen.
