APPARATUS FOR IDENTIFYING BATTERY DISCHARGES IN COMMUNICATION INABILITY ON WIRELESS CONTROLLING SYSTEM FOR ROOMS AND ITS IDENTIFYING METHOD THEREOF

摘要

An apparatus for discriminating the discharge of a battery in a communication-impossible state in a system for wirelessly controlling each room and a method thereof are provided to increase the usability and operationality of a consumer drastically. Warning data for informing that battery power is insufficient is prepared(S3). Data about various states is wirelessly received from wireless sub remote controllers(S7). It is determined whether the state information data is not received for a predetermined time(S9). If the warning data is received from a corresponding sub remote controller(S10), an error which is caused by the insufficient battery power is decided(S11).
