This makes it possible to automatically and accurately maintain the temperature inside the greenhouse according to the environment inside and outside the greenhouse, within a range of set values predetermined by the grower.
Furthermore, it is possible to minimize the number of operations of ventilation windows that are not desired to be operated as much as possible.
