If a room temperature sensor is connected, the actual value room temperature is used
for aborting quick setback.
If there is no sensor, the temperature of the room model is used to make the calcula-
tion. In that case, the setback time depends on the outside temperature and the build-
ing time constant.
The purpose of the "Boost heating" function is to have a shorter heating up time.
During boost heating, the room temperature setpoint is raised by an adjustable value.
The room temperature setpoint boost due to the morning boost and the room influence
bring about an increase of the flow temperature setpoint. The larger of the 2 influences
is active.
Morning boost is activated when a change is made from Economy mode or Protection
to Comfort or Precomfort mode and when the room temperature lies at least
0.25 K below the setpoint.

Limit and protective functions

10.8.1 Maximum limitation of the room temperature

If a room temperature sensor is connected, maximum limitation of the room tempera-
ture can be activated.
In contrast to room influence with modulating action on the flow temperature setpoint,
maximum limitation of the room temperature uses 2-position control.
When the actual value room temperature has exceeded the room temperature setpoint
by the adjustable room limitation increase, the heating circuit pump is deactivated.
⇒
When the pump is switched off, the heating circuit does not call for heat.
When the room temperature falls below the switch-off point by the amount of the room
switching differential, the heating circuit pump is switched on.
