Priority Size Explanation
Wiring test During the wiring test (highest priority), the plant
components can be directly controlled, independent
of all other settings
The controller-internal safety functions will
be overridden!
Plant operation selector The plant operation selector has the second highest
priority and can only be overridden by the control-
ler-internal frost protection functions
Electric immersion
heater
When the heat source changes to summer opera-
tion, DHW heating, if installed, will switch over to
the electric immersion heater.
The controller-internal frost protection functions
continue to be ensured. By contrast, the legionella
program will be overridden
Legionella protection The legionella program can be started in any of the
operating modes, with the exception of preselected
operating mode
“Protection”
Forced charging Using button “Forced charging” (DHW push),
recharging to the normal setpoint
can be triggered
in any of the operating modes. Forced charging can
also be performed during holiday periods
