REMARK: The remote controller transmits signal to indoor unit at 3 minutes intervals. If the indoor unit

has not received the signal for more than 10 minutes due to remote controller missing or other reason,

the sensor on indoor unit will be used for detecting indoor temperature automatically. Here, ambient

temperature of remote controller is likely to slightly different from that detecting by the indoor unit,

temperature will be compensated automatically. When the remote controller is missing or the batteries

are exhausted, please use the temporary switch.
