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 a room sensor an advance time point is calculated based on the outside
temperature and the building time constant (prog. no. 6110). The optimization
time (advance) is limited here to a maximum value. By setting the optimization
time = 0, the function is switched off.
