Protective functions
menu 7
F 7 - Protective functions
Menu
„7. Protections”
can be used by specialists to
activate and set various protective functions.
This does not under any circumstances
replace the safety facilities to be provided
by the customer!
The menu is closed by pressing
„esc”
or selecting
„Exit protections“
F 7.1 - Seizing protection
menu 7.1
If the anti-seizing protection is activated, the controller switches the pump and the valve on/off at 12:00 pm for
5 seconds to prevent seizing of the pump/valve after long periods of inactivity.
Setting range: on, off
Default: on
F 7.2 - Frost protection
menu 7.2
Frost protection function for the heating circuit. If the outdoor temperature at sensor S1 drops below 1
°C and
the heating circuit is switched off, the controller switches it back on with the reference temperature set in menu
7.3 (min.
fl
ow temperature). As soon as the outdoor temperature exceeds 1
°C ,the heating circuit is switched
off again.
Setting range: on, off
Default: on
Switching the frost protection function off or setting the minimum
fl
ow temperature too low can
lead to severe damage of the system.
F 7.3 - Min. flow temperature
menu 7.3
The minimum
fl
ow temperature is the lower limit for the characteristic curve/slope and as a result also for the
reference
fl
ow temperature of the heating circuit. Additionally, the min.
fl
ow temperature is the reference
fl
ow
temperature for the frost protection.
Setting range: 5
°C to 30
°C
Default: 15
°C
F 7.4 - Max. flow temperature
menu 7.4
This is used as the upper limit for the reference
fl
ow temperature of the heating circuit. Should the heating
circuit temperature exceed this value, the heating circuit is switched off until the temperature drops below. This
feature is used e.g. to protect under
fl
oor heating.
Setting range: 30
°C to 105
°C
Default: 45
°C
For safety, an additional limiting thermostat must be provided which is connected to the pump in
series.
F 7.5 - Anti Legionella
menu 7.5
When the anti Legionella function is active, the domestic hot water part at sensor S3 can be heated up to
a speci
fi
c temperature, provided that the energy is suf
fi
cient.
AL function - Setting range: On, Off / Default: Off
AL Tset - Setting range: 60
°C to 80
°C / Default: 70
°C
AL interval - Setting range: 1 to 28 days / Default: 7 days
AL heat: The last time the AL function completed successfully.
During the anti-Legionella function the storage tank is heated up to high temperatures which can lead to
scalding and damage to the system.
The operating times for the AL function have to be set in the
„Times”
menu (see 3.5)
This anti-Legionella function does not provide complete protection against Legionella, because the controller
is dependent on suf
fi
cient energy being fed in, and it is not possible to monitor the temperatures in the
entire range of the storage tanks and the connected piping system. To provide complete protection against
Legionella bacteria, it must be ensured that the temperature is raised to the necessary temperature, and at the
same time there must be water circulation in the storage tank and piping system by means of other additional
energy sources and control units.
7.6 Discharge protection
menu 7.6
To prevent unnecessary cool down of the system, the heating circuit is switched off when the buffer
temperature drops below reference temperature.
Settings range: On, Off / Default: Off
