During quick setback, the heating circuit pump is deactivated and, in the case of mixing
valve circuits, the mixing valve fully closed.
•
Function with room temperature sensor:
When using a room temperature 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 frost level, the heating
circuit pump will be activated and the mixing valve will be released.
•
Function without room temperature 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
