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.
