Claim 0:
1. A control system with a decentralized arrangement for adjustably operating a system undertaking operations, said control system comprising:
a plurality of control devices arranged in the system in a sequential order, wherein each respective control device of the plurality of control devices is configured to:
determine information at the respective control device comprising operational condition and a real-time measurement of at least one control parameter of the respective control device; and
share the information determined at the respective control device with at least one of the plurality of control devices in an upstream direction from the respective control device and at least one of the plurality of control devices in a downstream direction of the respective control device such that each of the plurality of control devices receive information shared from a different combination of the plurality of control devices; and
upon receipt of the information from at least one other one of the plurality of control devices at the respective control device indicating an out-of-tolerance condition, adjust an operational setpoint of said respective control device to a modified operational setpoint in accordance with the information received at the respective control device from the at least one other one of the plurality of control device;

wherein the control devices comprise heating systems and the control parameter comprises temperature; and
wherein each of the heating systems comprises a thermostat, a length of heat tracing line provided with electrical power through the thermostat, and a temperature sensor in contact with an object of the system to be heated by the length of heat tracing, the temperature sensor configured to provide a feedback input to the thermostat.
