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 5 hours, the clock and date must

be re-adjusted. Set Automatic Daylight Saving Time back to On if

you wish to continue using the feature.
