Abstract:
A thermostat, comprising:a low-profile thermostat housing configured for flush mounting onto a wall surface; a front cover of the thermostat housing; at least a first opening in the front cover of the thermostat housing, the first opening enabling ambient air to enter the housing; at least a second opening in the front cover of the thermostat housing, the second opening enabling air to exit the housing; a first temperature measurement chamber extending from the first opening; a second temperature measurement chamber extending from the second opening; a circuit board mounted in the thermostat housing; an elastomeric pad comprising a front surface and a back surface mounted between the front cover and the circuit board, wherein the first temperature measurement chamber and the second temperature measurement chamber are defined at least in part by the elastomeric pad and a front surface of the circuit board; a connecting air chamber within the thermostat housing, the connecting air chamber communicating with the first temperature measurement chamber and the second temperature measurement chamber; a temperature sensing element in the first temperature measurement chamber and thermally insulated at least in part by the elastomeric pad; and a heat generating element in the second temperature measurement chamber to create convective air flow causing an air flow into the first opening, across the temperature sensing element, and out the second opening.
