Power outage

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 thermostat returns to the mode of operation preceding
the power outage. If the power failure has exceeded 5 hours, the clock and
date must be re-adjusted.
Set the day and time that you want the temperature to
start rising so that the comfortable level is reached by
the time you arrive (e.g., Friday at 3:00 pm).
Set the day and time that you want the temperature to
start dropping to the economy level if you do not show
up (e.g., Friday at 8:00 pm).
