12.3.2 Switching off the DHW circuit
Note
If you want to switch off a DHW circuit, use the op -
erating program of the heat pump controller. Do not
disconnect the heat pump from the power supply.

12.4 Anti-legionella mode
Anti-legionella mode is designed to meet the hygiene re-
quirements for legionella bacteria.
For each DHW circuit, a time program can be used to start
anti-legionella mode. In this mode, the system is heated
to an increased target value and this value is maintained.
If the DHW temperature falls below the set switching dif-
ferential during anti-legionella mode, the system reheats.
1 Set target value
2 Set switching differential
3 Current temperature at temperature sensor
4 Heat demand
WARNING:
Incorrect settings for the target value and switching
differential may result in the build-up of legionella
bacteria.
»
Set the target value and the switching differ -
ential so that the DHW temperature cannot
fall below 60°C, even due to the switching dif-
ferential. (Target value - switching differential
> 60°C)
While anti-legionella mode is active, it will appear on the
main screen of the respective DHW circuit.
1 Anti-legionella mode is active.
After the period set in the time program expires, the con-
troller switches back automatically to the originally set
operating program.
Note
If the target value is not reached within the period
defined for anti-legionella mode, this mode remains
active until the target value is reached.
Note
The time program for anti-legionella mode takes
precedence over the time programs for the follow-
ing operating programs:
- ECO
- COMFORT
In order to save energy, we recommend that an-
ti-legionella mode is coordinated with the time
program for DHW mode. (See page 37, Example
of a DHW time program)
