Information

This models validates the block Buildings.Controls.OBC.Utilities.OptimalStart for the case when the optimal start is not turned on for preheating or precooling before the scheduled occupancy.

The results shows that the optimal start time tOpt remains zero and the optimal start on signal optOn remains false during the simulation.
