Classification: CPC F | IPC F

Claim 0:
1. An air conditioning system comprising:
a controller that controls an air conditioner;
a thermostat that
measures a temperature of an air conditioning target space,
changes a contact point to an ON state or an OFF state in accordance with a measurement result, and
manages input of a control signal to the controller to control operation of a component of the air conditioner;

a connection line group that electrically connects the thermostat and the controller, wherein the connection line group includes 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;
a relay that switches, to either a conductive state or a cut-off state, at least one of
the compressor operation command communication line and the fan operation command communication line;
a leakage detection sensor that detects refrigerant leakage from the air conditioner, and outputs a signal that controls the relay; and
a heater that is disposed separately from the air conditioner and that heats the air conditioning target space, 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.
