Classification: CPC F | IPC F

Claim 18:
19. A control system, said control system comprising:
a plurality of cooling systems, each cooling system of said plurality of cooling systems comprising
a motor connected to a fan operable in a forward direction and a reverse direction, the fan positioned before a coil of a cooling system of the plurality of cooling systems;
a motor performance sensor;
a local memory; and
a processor communicatively coupled to said motor, said motor performance sensor, and said memory and configured to control operation of said motor according to settings defined by configuration data stored in said memory; and

a server comprising a processor communicatively coupled to said plurality of cooling systems and communicatively coupled to a memory device configured to store instructions, wherein in response to reading the instructions, said processor is configured to:
instruct the processor of at least one cooling system of the plurality of cooling systems to periodically run the corresponding cooling system motor in a reverse direction opposite a normal operating direction over a measurement time;
receive, from a static air pressure sensor and motor performance sensor of each of a plurality of cooling systems a measurement sensor data over the measurement time; and,
instruct the processor of at least one cooling system of the plurality of cooling systems to determine if power draw from the measurement data has exceeded power draw of the configuration data.
