ABSTRACT:
A rotatable knob for adjusting the temperature setting of a thermostat has a deformable tab that is permanently deformed upon rotational movement of the knob to a position that is indicative of a temperature setting greater than a predetermined optimum temperature setting. A deformed tab demonstrates that the knob was moved to a position for setting the thermostat at a temperature greater than the optimum temperature setting.
