Abstract: A remote controller controlling an air-conditioning apparatus includes: a main part, a three-axis acceleration sensor; a normality determination part that determines whether an installation state of the remote controller is in a normal installation state or in an abnormal installation state, based on a detection value of the acceleration sensor; a stationary state determination part that determines whether the installation state is in a stationary state; a vibration determination part that determines whether a vibration occurs; a thermo sensor; and a control part that controls the air-conditioning apparatus. The main part includes a back face, a front face, and a bottom. The remote controller is in the abnormal installation state due to a shape and a centroid when the remote controller is placed on a horizontal surface. The control part performs a limited control that includes limitation of a control of the air-conditioning apparatus based on the environment temperature.

Abstract: An air-conditioning control system, which controls a central-type air-conditioning system, includes a plurality of auxiliary controllers respectively set in a plurality of areas and a main controller capable of communicating with each auxiliary controller. Each auxiliary controller includes a sound wave receiving unit, which receive sound waves that are outputted from a portable apparatus capable of outputting sound waves, and a sound wave strength information transmitting unit which transmits, to the main controller, sound wave strength information indicating sound wave reception strength.

Abstract: A controller as a CO2 sensor reference value calibration apparatus calibrates a reference value of the CO2 sensor in the following manner. Introduction of outside air is started after a person is not detected. A CO2 concentration, which is acquired when a preset first waiting time elapses, is set as a provisional reference value. The carbon dioxide concentration, which is acquired when a preset second waiting time elapses, is compared with the provisional reference value. In a case where a change rate of the carbon dioxide concentration is out of a preset allowable range, the carbon dioxide concentration is acquired when the second waiting time elapses after newly setting the acquired carbon dioxide concentration as the provisional reference value. In a case where the change rate of the carbon dioxide concentration is in the allowable range, the currently set provisional reference value is set as the reference value.

Abstract: A proximity sensor of the electrostatic type has a pulse-generating circuit and first and second delay circuits which are respectively connected to an output of the pulse-generating circuit. The first and second delay circuits are of the integrating type having capacitances which are charged over time. The second delay circuit is a reference circuit and has a delay based on a fixed capacitance. The first delay circuit has its capacitance based on a capacitance of a detection electrode. The first and second delay circuits each have their respective capacitances charged or drained by constant current circuits, each moving the same amount of current. Outputs of the first and second delay circuits are each applied to a respective limiting amplifier such as a Schmitt trigger, each Schmitt trigger then has an output to input to a common phase detector. The phase detector determines the sequence of arrival of pulses generated by the first and second delay circuits.
