ABSTRACT:
A replacement cover is provided for a wall mounted, circular thermostat. The replacement cover engages the rotatable sub-assembly of a wall mounted, circular thermostat and provides a transparent convex lens for enlarging the appearance of temperature indications. In a preferred embodiment a lamp is mounted in the replacement cover to illuminate the temperature indications for easier reading. The lighting circuit includes a battery, a lamp bulb and a normally open switch which can be closed by the operator/viewer of the thermostat.
