The quick setback is active if the room setpoint is switched from comfort level to
another operating level (selected between reduced mode or protection mode).
During the quick setback the heating circuit pump is turned off and the mixing
valve is also closed during mixing circuits. During the quick setback no heat re-
quirement is sent to the heat generator.
The quick setback is possible with or without room sensor: with room sensor the
heating circle function is switched off as long as the room temperature is above
the reduced setpoint or frost protection setpoint. If the room temperature is
above the reduced setpoint or the frost protection setpoint, the heating circuit
pump is switched on again and the mixing valve is released. Without the room
sensor the quick setback switched the heater off depending on the outside tem-
perature and the building time constant (prog.no. 6110) as long as the tempera-
ture has theoretically dropped to the reduced target value or the frost protection
value.

The optimization of the on/off switching time is a function of time and possible
with or without the room unit. With a room unit the conversion of the operating
level compared to the programmed time point is moved forward so that the
building dynamics (heat up and cool down time) is considered. In this way the de-
sired temperature level is reached exactly at the programmed time point. If this is
not the case (too early or too late) a new switching time point is calculated which
is used the next time.
Without room sensor an advance time is calculated based on the outside temper-
ature and the building time constant (prog. no. 6110). The optimization time (ad-
vance) is limited here to a maximum value. By setting the optimization time = 0,
the function is switched off.
