Thermostat: Industrial interface design example

I find industrial interface design captivating because they work with so many constraints. Look at what this designer was faced with when applying labels to this thermostat: four teeny-tiny buttons.

I admire how the designer used icons and created boxes around the small buttons. The icons reinforce the meaning and the boxes increase the perceived size of each button. Well done, SensorStat! An excellent example of working within physical limits.
