An HVAC control unit (10) is formed of a molded, electrically insulative material. The HVAC control unit (10) has a wall plate (36) and a cover plate (14). The wall plate (36) attaches to a standard electrical box (54) and has an opening for wires (66), and a cover plate (14) attaches to the wall plate (36) forming a sensor compartment (20, 22) a temperature sensitive chamber (20) and an electrical component chamber (22). Electrical contacts (38) extend through the separation wall (18). The cover plate (14) includes lower and upper ventilation openings (24, 25, 26, 27) to allow unforced air flow from the outside room through the temperature sensitive chamber (20). The vertical separation wall (18) restricts air flow between the two chambers (20, 22), closing the temperature sensitive chamber (20) to the electrical component chamber (22).

L'invention concerne une unité de commande de CVC (10) réalisée dans un matériau électroisolant moulé. Cette unité de commande de CVC (10) comporte un panneau de paroi (36) et un panneau de couverture (14). Le panneau de paroi (36) est fixé sur un boîtier électrique standard (54) et comporte une ouverture conçue pour des fils (66), et un panneau de couverture (14) est fixé sur le panneau de paroi (36) formant ainsi un compartiment de capteur (20, 22) composé d'une chambre sensible à la température (20), et d'une chambre de composants électriques (22). Des contacts électriques (38) s'étendent au travers d'une paroi de séparation (18). Le panneau de couverture (14) comporte des ouvertures de ventilation inférieures et supérieures (24, 25, 26, 27) pour permettre un courant d'air non forcé de la chambre extérieure au travers de la chambre sensible à la température (20). La paroi de séparation verticale (18) empêche le courant d'air entre les deux chambres (20, 22) par fermeture entre la chambre sensible à la température (20) et la chambre de composants électriques (22).
