Caution
- You may use ALL_OFF command to turn on all the indoor units but it is not recommended.
- If communication error occurs on devices such as SIM, On/Off Controller, Interface Module etc., other functions such as power distribution may also create a problem. You must have BMS system to check the errors and you must take action immediately.
