PROBLEM TO BE SOLVED: To improve the efficiency of the data transmission without achieving the unnecessary transmission by controlling the transmission time interval according to the environmental detected value, and transmitting the environmental detected value at the frequency corresponding to the environmental condition from an environmental detecting device to a dwelling equipment. SOLUTION: An equipment control means 111 controls the frequency of a compressor of a dwelling equipment (air conditioner) 102 so that the room temperature is the set value Th1 when a person is 'present', and the room temperature is the waiting temperature Th0 higher than the set temperature Th1 for energy saving when a person is 'absent'. When a person enters a room and the presence is detected, an environmental detecting device 101 transmits the temperature detection value with a short time interval. The equipment control means 111 controls the frequency of a compressor of the air conditioner 102 based on the received temperature detection value to rapidly stabilize the room temperature controlled to the waiting temperature Th0 to the set temperature Th1 . When the person leaves the room, the environmental detecting device 101 transmits the temperature detection value with a long interval, and the frequency of the air conditioner 102 is controlled based on the received temperature detection value. |
