Why can't I save my schedule for my smart thermostat MTS100, and it keeps showing an error code?

Please press the UP and DOWN buttons simultaneously for 5 seconds to reset the device and pair it with the hub again. 
If the issue persists, please log out and log in to your meross account and try again.
