During a power outage, the thermostat display remains lit for the
first 2 minutes. During this time, the LP (low power) indicator
appears and all buttons are disabled. Then the screen turns blank.
The settings are stored in memory. When power returns, the ther-
mostat returns to the mode of operation preceding the power out-
age. If the power failure exceeded 5hours, the clock and date must
be re-adjusted. Set Automatic Daylight Saving Time back to On if
you wish to continue using the feature.
