10.11.3 Circulating pump
A circulating pump can be configured for DHW circulation.
The output is to be activated via "Extra configuration":
Main menu > Commissioning > Extra configuration > DHW > Outputs... > Circulating
pump
Assign terminal
Control can take place via a specific time program or depending on user requirements
(DHW time switch). Using setting Acc to DHW time switch , the circulating pump will
run during operating mode "Normal ".
By activating the circulating pump for the period of time the legionella function is per-
formed, the circulation pipe can also be protected against legionella viruses
For detailed information, refer to subsection 10.6.2 "Sequence of legionella function".

External circulating pump
The circulating pump can be operated according to the time switch or, using this set-
ting, can be made to run constantly (24-hour operation). This setting will be overridden
when preselecting "Off" with the DHW operating mode, which means that the circulating
pump will also be deactivated.
The circulating pump can be operated according to its time switch or the DHW time
switch. This setting will be active only if "Operation circulating pump" is set to "Time
switch".
In interval operation, the circulating pump runs for 10 minutes at 30-minute intervals
(every full and every half hour), resulting in off times of 20 minutes. The pump runs only
when enabled according to the time switch or parameterization. When enabling is
started, the pump always runs for 10 minutes, independent of the time of day. But this
does not apply when turning on power or when leaving commissioning.
Some of the functions require a circulating pump, such as the legionella function in
connection with consumer control or direct DHW heating. If a circulating pump is in
operation that is independent of the controller, this can be communicated to the control-
ler by making use of this setting.

To include the circulating pump in the legionella function, this setting can be used to
activate the pump for the period of time the legionella function is performed. When using
setting Time switch , the legionella function has no influence on the circulating pump.
