Clock setting¶
Normally the clock is automatically set once Wi-Fi is connected and synchronize for each day. So manual set is not necessary when it is online.
- Press to start the setting
- Press / to change the day of week
- Press again to confirm day of week setting and start to adjust hour
- Press / to change the hour
- Press again to confirm hour setting and start to adjust minutes
- Press / to change the minutes
- Press again to confirm minutes setting and start to adjust day of week
- Press [blank] to confirm or leave the clock setting. Or return after no key pressed for 20 seconds.
Clock synchronization¶
When Wi-Fi is connected and time synchronization is need. Please use the App for time synchronization.
Schedule Programming¶
When 1 day / 5+1+1 day / 7day program is selected in internal setting.
Override Temperature¶
The Set point can be adjusted by / .
When it is in program mode, the set point will be overwritten until the next time slot.
