Auto-recovery Mode
The thermostat has an auto-recovery function that brings your room
temperature to the set temperature of comfortable mode exactly at
the pre-set time by turning on the Heating/Cooling system earlier. When
it finds that the operation mode needs to change to comfortable mode
at the coming hour, it will turn on the Heating/Cooling system for a
short period to estimate the Heating/Cooling rate. Then, the thermostat
will continuously monitor the room temperature and estimate the time
required to heat-up/cool-down the room temperature to the set
temperature of comfortable mode. Once the unit finds that the
remaining time is just enough to bring the room temperature to the set
temperature of comfortable mode, it will turn on the Heating/Cooling
system, with flashing the comfortable mode icon .
Any key press during the auto-recovery mode will terminate the
process immediately and return to the current operation mode.
