Power Outage

During a power outage, the thermostat display remains lit for approximately the first 15 minutes during which the LP (low power) indicator appears. The settings are saved 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.
