ABSTRACT:
A thermostat having a cover plate rotatable about a central horizontal support in which a bimetal or other thermally responsive member supported on the cover plate actuates a mercury switch also on the cover plate. This cover plate also has upon it indicia such as degree marks or simply arrows indicating "colder -- warmer" operable against an imaginary vertical lubber line to indicate a setting. The need for time consuming and expensive levelling of the thermostat during installation is thus obviated because the thermostat is automatically levelled by the user as a result of setting the indicia in relation to the imaginary vertical line.
