The "Room temperature limitation" function enables the heating circuit pump to be
deactivated should the room temperature exceed the current room temperature
setpoint by more than the adjusted differential.
The heating circuit pump will be 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 work in the case of 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 is possible with or without room temperature sensor.
