Abstract
A thermostat for controlling heating and cooling apparatuses has a temperature control point adjustment knob connected to a temperature responsive switch means for adjusting the control point thereof. A single lever changeover switch is connected to the temperature responsive switch for selectively connecting either heating or cooling apparatus to the temperature responsive switch. Temperature control point limit stops are connected to the temperature control point adjustment. Upon selecting by the single lever changeover switch either a heating or a cooling operation, the temperature control point limit stops limit the movement of the temperature control point adjustment to a first range of movement when heating is selected and a second range of movement when cooling is selected.
