temperature is 70° by the time you wake at 6. The message "Recovery" is displayed
when the system is activated before a scheduled time period.
Compressor Protection: This feature forces the compressor to wait a few minutes

CAUTION: To avoid possible compressor damage, do not use Auto Changeover if the
outside temperature drops below 50°F (10°C).
