Abstract
A visual display system and method for a digital thermostat having a user display screen to provide operational status information of the heating and/or cooling equipment controlled by the thermostat is provided. This visual display system utilizes animated icons to show operational status of the heating and/or cooling equipment. Static icons may also be used in one embodiment to indicate the current mode of the thermostat. Animated icons for the heating system, the cooling system, and fan operation are provided. The illusion of animation is provided by overwriting or replacing a displayed image with another image at a predetermined frequency. This predetermined frequency may be changed programmatically, and varied to provide different visual effects.
