The invention relates to a method for managing a main module (1) of a production line, with said main module (1) being equipped with thermal means that operate in production at a setpoint temperature (1000), method in which during production, when there is a break in production continuity at said main module (1), the temperature of said thermal means is lowered, and then their temperature is reset until said setpoint temperature (1000) is reached. Advantageously, at least data from a past event comprising at least one temperature rise time of said thermal means from a first temperature to a second temperature is recorded, and based on said data, the temperature of said thermal means is adapted automatically to reach said setpoint temperature (1000), at the latest when the production continuity resumes at said main module (1). The object of the invention is also a corresponding management device.
