Display backlighting

The display has two levels of lighting, high level and continuous low level. High level lighting comes on for 10 seconds any time a button is pressed. Continuous low level lighting is only available if the thermostat is operated from 24VAC. It is not available with batteries. Continuous low level backlighting is a configurable option (see configuration settings above).
