IMPROVEMENTS IN OR RELATING TO REDUCING ENERGY CONSUMPTION OF AN ENERGISABLE DEVICE

摘要

A controller (10) is provided which is capable of time-dependently periodically deactivating and reactivating an energisable device to reduce an energy consumption of the energisable device. The controller (10) includes a processor which can accept a global performance profile (GPP) which is comprised at least in part from an adaptive performance profile (APP) which utilises data external to the controller (10) in order to modify the period and/or frequency of the periodic deactivation and reactivation of the energisable device during its activation period. The adaptive performance profile (APP) being formed at least in part from a predetermined data set, map or profile.
