Quick setback

Example
Siemens Schweiz AG
HVAC Products
Boost heating is used to reach the new setpoint more quickly when switching from the
Reduced setpoint to the Comfort setpoint, thus reducing 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 sensor.

During quick setback, the heating circuit pump is deactivated and, in the case of mixing
circuits, the mixing valve is fully closed.
Function with room sensor:
When using the room sensor, the function keeps the heating switched off until the room
temperature has dropped to the level of the Reduced setpoint or the frost level.
When the room temperature has fallen to the Reduced level or the frost level, the
heating circuit pump will be activated and the mixing valve will be released.
Function without room sensor:
Quick setback switches the heating off for a certain period of time, depending on the
outside temperature and the building time constant.
Duration of quick setback when Comfort setpoint minus Reduced setpoint = 2 °C
(e.g. Comfort setpoint = 20 °C, Reduced setpoint =18 °C).
