The factory settings are highlighted in the following table.
Comment/restriction
Not used
The factory default for installations without the optional
diverter valve kit, is "Not installed",
Where the optional diverter valve kit is installed, the
boiler will automatically detect its presence and adjust
the default setting to "3-way valve installed"
Not used
Maximum released thermal output [%] (heating).
On natural gas appliances:
▶ Measure the gas rate.
▶ Correct deviations.
The time interval determines the minimum delay between
starting and restarting the burner.
The difference between the current flow temperature and
the set flow temperature until the burner is switched off.
The difference between the current flow temperature and
the set flow temperature until the burner is switched on.
Maximum power on hot water
No functionality; not used.
Menu only visible if DHW circ. pump is installed and set to
"On"
Number and duration of hot water circulation pump starts
per hour
Thermal Disinfection hot water temperature set point.
Start legionella protection cycle
▶ Perform thermal disinfection
( Chapter 7.3, page 58).
Stop legionella protection cycle
▶ In order to save energy and to keep potential flow
noises to a minimum, set a low pump curve
( Chapter 13.5, page 89).
• Save energy: intelligent shutdown of heat pump for
heating systems with weather-compensated
controller. The heating pump is only switched on if
required.
• With heat demand: the flow temperature controller
switches the heating pump. When there is heat energy
demand, the heating pump starts up with the burner.
