Abstract

A method (400) for commissioning a plurality of sensors in an environment cooled by a plurality of cooling devices includes measuring (410) an initial temperature at each of the plurality of sensors in the environment, modifying (420) a cooling setting of a first of the plurality of cooling devices, the cooling setting corresponding to an air handler temperature of the first cooling device and determining (430) an influence factor of the first of the plurality of cooling devices for each of the plurality of sensors, the influence factor including a magnitude of change and a rate of change for each of the plurality of sensors. A system is also provided.
