Abstract
An electronically controlled thermostat has an emergency power configuration which only provides long term emergency power to a real time clock. All other components of the thermostat function only for a limited period of time following a power outage. Emergency power to the other components is monitored during power outage with appropriate action being taken to assure that control information has been stored in nonvolatile memory before emergency power deteriorates to a critical level.
