Method for maintaining an equilibrium of a physico-chemical parameter of a medium, associated computer program product and electronic module

A method for maintaining an equilibrium of a physico-chemical parameter of a medium, said method being implemented by a processing unit of a system for regulating said medium, said processing unit cooperating with memory recording data relating to a medium parameter, said memory comprising:

• a recording dedicated to said medium parameter and configured to store a current value of said parameter and a nominal value;
• said method comprises:
• a step for reading the current value of said parameter;
• a step for reading the nominal value of said parameter;
• a step for estimating a distance between said nominal value and the current value;
• a step for triggering an action depending on the value of said distance;
• wherein:
• the recording dedicated to said medium parameter comprises a field for storing a time limit value for recovering a determined nominal value;
• said method further comprises:
• before the step for triggering an action, a step for reading the value of the field for storing a time limit value;
• the step for triggering an action depending on said distance being implemented if and only if
• the value of the field for storing a time limit value comprises a predetermined value characterizing the absence of definition of a time limit (104-0) for recovering a determined nominal value.
