Classification: CPC F | IPC F

Claim 5:
6. A method of controlling an air conditioning system, the method comprising:
controlling an air conditioner with a controller;
measuring, with a thermostat, a temperature of an air conditioning target space;
changing, with the thermostat, a contact point to an ON state or an OFF state in accordance with a measurement result;
managing, with the thermostat, input of a control signal to the controller that controls operation of a component of the air conditioner;
connecting the thermostat and the controller with a connection line group including a compressor operation command communication line that controls a compressor of the air conditioner and a fan operation command communication line that controls an indoor fan of the air conditioner;
controlling, with a relay, a conductive state or a cut-off state of at least one of the compressor operation command communication line and the fan operation command communication line;
detecting, with a leakage detection sensor, refrigerant leakage from the air conditioner;
outputting, with the leakage detection sensor, a signal that controls the relay; and
heating the air conditioning target space with a heater that is disposed separately from the air conditioner, wherein
the connection line group further includes a heating operation command communication line that controls the heater, and
when the leakage detection sensor detects refrigerant leakage from the air conditioner, the relay switches the heating operation command communication line to either a conductive state or a cut-off state.
