1. A cabin temperature control system comprising:
an environmental control system controller configured to supply clean air at a set temperature to an aircraft cabin;
a set point controller communicatively coupled to the controller; and
one or more micro-climate conditioners positioned in the aircraft cabin and communicatively coupled to the set point controller, each micro-climate conditioner configured to receive and supply the clean air to at least one seat positioned in the cabin, each micro-climate conditioner further configured to enter a temperature change request;
wherein the environmental controller, upon receiving temperature change requests from the one or more micro-climate conditioners through the set point controller, is further configured to:
decrease the set temperature upon receiving a number of decrease temperature change requests exceeding a predetermined threshold number of decrease temperature change requests; and
in an absence of the number of decrease temperature change requests received exceeding the predetermined threshold number of decrease temperature change requests, and if a previous change implemented by the environmental controller was not a decrease to the set temperature, increase the set temperature.
