Device for automatically regulating the temperature of sheep sheds including sliding or skylight windows. It consists of a threaded part integral with a cable driven in translation by the rotation of a threaded rod, itself driven by a direct current motor 1 whose direction of rotation 2 is a function of two, maximum and minimum, thermostats. The power supply to the assembly is divided up 3 in such a way as to reduce the speed of progress. The power supply source is a battery 4, the apparatus is therefore independent. This device is particularly intended to keep a fixed temperature in sheep sheds equipped with openings controlled by cable. <IMAGE>
