16.1.5 Operation of circulating pump

Operating line 150 is used to select whether the legionella function shall act on the
d.h.w. circulating pump:
With setting 0, the legionella function does not act on the circulating pump
With setting 1, the legionella function acts on the circulating pump

16.2 Mode of operation

Preconditions for the legionella function:
The storage tank temperature is acquired by 1 or 2 sensors (legionella function
with thermostats is not possible)
The legionella function was activated by defining a setpoint (operating line 130).
D.h.w. heating is on (button
The holiday function is not active
Charging is effected via the heating system and not with the electric immersion
heater
If the criteria of periodicity and starting time are fulfilled, the legionella function is
released. Release of the legionella function means that the d.h.w. temperature
setpoint is raised to the level of the legionella setpoint and that forced charging is
triggered.
If d.h.w. heating is off, or the holiday function or operating mode changeover is
active, the legionella function is released, but not the setpoint boost. On completion
of the overriding function, d.h.w. charging to the legionella setpoint is started since
release of the legionella function is maintained.
