PROBLEM TO BE SOLVED: To provide a double-lined load control device having a wireless reception function capable of preventing a CPU from being reset due to a failure of the power for own circuit while continuously receiving control signals in a wireless manner.SOLUTION: The double-lined load control device which is connected in series between a commercial power supply and a load includes: a wireless reception section that controls signals transmitted from a radio transmitter and receives the same; and a power supply section that ensures the power to a control section and a radio transmitting section even when the load is OFF. When the load is OFF, the control section switches between a sleep state (#2) where the wireless reception section is not activated to ensure the power from the power supply section and a waiting state (#3) in which radio signals are receivable and performs an analysis after receiving a radio signal (#3-#10). As a result of the analysis, when the received radio signals are control signals intended to own machine (YES in #6), or when radio signals which are control signals not intended to own machine are received predetermined times (YES in #10), a sleeping period T1 immediately after the reception is set to be longer than the previous sleeping period (#8). |
