During a power outage, the thermostat display remains lit for approx-
imately the next 15 minutes during which the LP (low power) indica-
tor appears. The settings are stored in memory. However, if the
power failure exceeds 5 hours, only the thermostat’s clock must be
re-adjusted. When power returns, the thermostat returns to the mode
of operation preceding the power outage.
