The maximum forward shift can also be set. Optimum start control can be deactivated
by entering 0 hours as the maximum heating up period.

Optimum stop control switches off the heating circuit at the earliest possible point in
time so that the room temperature will lie 0.5 K below the Comfort or Precomfort set-
point when the time switch changes from Comfort or Precomfort mode to Economy or
Protection mode.
Optimum stop control is possible only when type of optimization “With room temperature
sensor“ has been selected.

Quick setback and boost heating
The purpose of quick setback is to reach the new setpoint as quickly as possible when
changing the room operating mode.
During the time quick setback is active, the heating circuit pump is deactivated and the
heating circuit’s mixing valve fully closed. The heating circuit remains off until the
required room temperature is reached.
The “Quick setback“ function can be deactivated on the service level.

Quick setback is started when the room operating mode changes from Comfort or
Precomfort to Economy or Protection .
It will be ended when the room temperature has reached the new setpoint or when a
change back to Comfort mode is made.
If a room temperature sensor is installed, the actual value of the room temperature will
be 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 will depend on the outside temperature and the
building time constant.
The purpose of the “Boost heating” function is to work with shorter heating up times.
During the time boost heating is active, the room temperature setpoint is raised by an
adjustable value.
The room temperature setpoint increase heating due to boost heating and the room
influence produce an increase of the flow temperature setpoint. The larger of the 2
influences will prevail.
