Child lock
The standard display settings and in the menu can only be modified if the
child lock (key lock) has been disabled ( page 8).
Mixing device
Assembly that automatically ensures that hot water can be drawn from
the taps at a temperature no higher than the temperature set on the
mixer.
Optimised operation
Automatic mode (the heating time program) is not active during
optimized operation, instead the system is continuously heating
according to the temperature set for optimized operation.
Reference room
The reference room is the room in the home where a room unit has been
installed. The room temperature in this room acts as the control variable
for the assigned heating circuit.
Switching time
A certain time at which the heating system starts to heat or hot water is
produced, for example. A switching time is a component of a time
program.
Temperature of an operating mode
A temperature that is assigned to an operating mode. The temperature is
adjustable. See the explanations on operating mode.
Flow temperature
Temperature at which the heated water flows in the central heating
system from the heat source to the heating surfaces in the rooms.
Hot water cylinder
A hot water cylinder stores large volumes of heated tap DHW. Thereby,
sufficient DHW is available at the draw-off points (e.g. taps). This is a
prerequisite for longer hot showers.
Time program for the heating system
This time program ensures automatic changeover between operating
modes at defined switching times.
