Backlighting (INDIGLO® | 47 |
Your thermostat has an electroluminescent lamp that backlights the display for easy viewing in the dark.
When any key is pressed the display is illuminated.
The display will remain illuminated for 15 seconds after the last key is pressed. This allows the light to stay on if you need to op-
erate several keys. The backlight will decrease in brightness before shutting off.
NOTE: The backlight is powered by the 24V AC supply. It will not operate when there is an AC power interruption or if the thermostat is removed from the wallplate.
