The "Room temperature limitation" function enables the heating circuit pump to be
deactivated if the room temperature exceeds the current room temperature
setpoint by more than the adjusted differential.
The heating circuit pump is activated again as soon as the room temperature
returns to a level below the current room temperature setpoint.
During the time the "Room temperature limitation" function is active, no heat
request is sent to the heat source.
Room temperature limitation does not function with pure weather compensation.

Boost heating is used to reach the new setpoint more quickly when switching from
the Reduced setpoint to the Comfort setpoint, thus shortening the heating up time.
During boost heating, the room temperature setpoint is raised by the value set
here.
A higher setting leads to shorter heating up times, a lower setting to longer heating
up times.
Boost heating can be provided with or without room sensor.
