Circulating pump
A multifunctional relay is used for cont-
rolling the circulating pump. It must be
appropriately parameterized.
Circulating pump release
The circulating pump is switched on
during the release time (see below),
provided DHW heating is switched on
and at least one of the connected hea-
ting circuits is not in holiday mode. If
the DHW operating mode is "Off", or if
all connected heating circuits are in
holiday mode, the circulating pump
remains deactivated, independent of
the parameterized release. Release of
the circulating pump can take place in
different ways:
Time program 3/HCP
The circulating pump is released accor-
ding to time program 3 / HCP.
DHW release
With this parameterization, the circula-
ting pump is released when DHW hea-
ting is released
also.
Trinkwasser Freigabe
Bei dieser Parametrierung ist Zirkulati-
onspumpe freigegeben wenn auch die
Trinkwasserbereitung
freigegeben ist.
Time program 4/DHW
The circulating pump is released accor-
ding to time program 4 / DHW.
Time program 5
The circulating pump is released accor-
ding to time program 5.

Circulating pump cycling
When the function is activated, the cir-
culating pump is switched on for 10
minutes whithin the release time and
then switched off again for 20 minutes.
Circulating setpoint
If a sensor is installed in the DHW dis-
tribution pipe, the controller will monitor
its actual value during the time the le-
gionella function is performed. The ad-
justed setpoint must be maintained at
the sensor during the adjusted Dwelling
time. The circulating setpoint is limited
at the top at the nominal setpoint.
