Temperature Recovery Feature
Your thermostat is equipped with a feature that accommo-
dates recovery time to ensure your comfort.
Recovery time is the time that it takes your heating and cool-
ing equipment to recover from energy−saving settings pro-
grammed during away or asleep periods. Recovery time
depends on local weather, your schedule, the contruction of
your home and your heating and/or cooling equipment.
Your thermostat tracks the time that it takes for your system
to reach your desired settings (recovery period). This allows
the thermostat to accommodate this recovery period and to
ensure your comfort at the programmed wake and return
settings.
For example, your WAKE period is programmed for 6:00
a.m. and 70°F. The thermostat activates heating in advance
of 6:00 a.m. to ensure that your desired comfort setting of
70°F is reached by the time you awake.
A recovery notice is displayed when the system is operating
before the scheduled time.
