days the filter is used. When the recorded number of days reaches the
preset value, the main display will flash with the filter icon to prompt
you to replace or clean the filter.
Pre-cooling/preheating
This function works with your TIMING schedules. When the pre-
cooling/preheating function is enabled, the thermostat will calculate how
far in advance it should start so that once the scheduled time arrives, the
desired room temperature range has already been achieved. The
“Recovery” character will be shown on the main display screen when pre-
cooling/preheating has been initiated.
