Abstract
A sensor and control module have a housing with an internally mounted printed circuit board which supports a sensing element located in an outwardly projecting hollow portion formed at the lower part of the housing. The projecting portion is prism-shaped and includes air intake slots at its bottom side to enable external air to reach the element. The upper side of the projecting portion which is adjacent to control elements on the module is sealed. The housing is provided with an internal air passage adjacent to the printed circuit board between the air intake slots and air exit slots at a top side of the housing spaced from the control elements. In one embodiment, the module is a thermostat, and the sensing element is a temperature responsive resistor used to sense air temperature.
