Zusammenfassung:	Chiller systems can include a controller that is configured to determine whether to restart the chiller in a rapid restart mode or a soft loading restart mode, and methods can include determining the mode for restarting the chiller. The soft loading restart mode controls the chiller to provide a comparatively gradual loading, to avoid overshooting a target temperature. The rapid restart mode more aggressively loads the chiller to return more rapidly to a particular load level. The determination of the restarting mode can be based on characteristics of the interruption of power to the chiller system. In chiller systems, the controller can receive power from an uninterruptable power source to maintain continuity of power. The logic used by the controller can be based on whether or not the controller shares continuity of power with other components of the chiller system.
