means the timer is off. Tap the schedule to edit it. You may modify the time, days of the week, and adjust the heat and cool temperature ranges. Note that up to 12 timers can be set. Key Lock Password setting:
Each time you enable the key lock you will need to enter a new password. This password will save until Key Lock is disabled. When the Standby parameter is set to Never and the Key Lock is enabled, the Key Lock will activate once the thermostat has been idle for 30 seconds. When the Standby time is set to any other time value and the Key Lock is enabled, the main interface will lock immediately. When the system is locked, changing the main interface state, System Mode or Setting will require you to input the Key Lock password.

The thermostat will keep track of the number of 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.
