摘要：
A thermostat adapted for controlling heating and cooling apparatuses has a temperature control point adjustment means connected to a temperature responsive switch means for adjusting the control point thereof. A changeover switch means is connected to the temperature responsive switch means for selectively connecting either heating or cooling apparatus to the temperature responsive switch means. A temperature control point limit means is connected to the temperature control point adjustment means so that upon selecting by means of the changeover switch means either a heating or a cooling operation, the temperature control point limit means limits the movement of the temperature control point adjustment means to a first range of movement when heating is selected and a second range of movement when cooling is selected.
