PASSIVE DEVICE SETTING RECOMMENDATION INDICATOR BASED ON AMBIENT TEMPERATURE

Abstract

The invention relates to a display device that does not require electrical energy, consisting of a carrier body (11) separated from the outer casing (2) of the cooling device by means of a thermal insulation spacer (13), an air gap (14) created between the carrier body and the outer casing of the device, air passage openings (15, 16) and an outside air path (17) that allow the circulation of outside air, reversible thermochromic elements (20) with different threshold temperatures, a detachable adjustment scale (30) that can be changed according to different device models, and complementary asymmetric mechanical register slot (32) and mechanical register protrusion (33) that ensure that the said scale is placed in the correct position and direction.
