10.8.3 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.
When quick setback is active, the heating circuit pump is switched off and the heating
circuit mixing valve shut. The heating circuit remains switched off until the required
room temperature is reached.
The "Quick setback" function can be deactivated at the service level.

Quick setback
Quick setback is started when the room operating mode changes from Comfort
Precomfort to Economy or Protection
room temperature has reached the new setpoint or when a change back to Comfort
mode is made.
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 will depend on the outside temperature and the
building 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
will be active.
Morning boost will be activated when a change is made from Economy mode or Pro-
