NOTICE
If different faulty events occur at the same time, sensor/DAC LED lights up following the
priority below: Red (Fast Blinking) -> Red (On, Steady) -> Red (Blinking) -> Yellow -> Off ->
Green. For example, if there is a humidity sensor error and air temperature failure at the
same time, the sensor LED turns red rather than yellow.
After the Economizer controller enters the running state, it may take one minute for
peripheral devices to complete initialization. Before that, LED indication might be unstable.
