Optimum stop control

Optimum stop control acts only when a room sensor is used and when room influence
is active.
The maximum forward shift can be set with parameter "Maximum forward shift with
optimum stop control" (range is 0...6 h). This parameter can also be used to switch
optimum stop control off (setting = 0).
During occupancy hours, the heating is maintained at the nominal level. Towards the
end of the occupancy time, the control switches to the reduced level.
Optimization calculates the changeover time such that, at the end of occupancy time,
the room temperature will be 0.5 °C below the nominal setpoint (early shutdown).
Adaption takes place only with the first occupancy period per day. The switch-off point
is adapted in steps of 10 minutes. If the 0.25 K are not reached, the switch-off point is
shifted forward by 10 minutes (earlier shutdown). In the other case, the switch-off point
is shifted backward by 10 minutes (later shutdown).
