Claims (1)

[Scope of utility model registration request] In an automatic switching device for heating and cooling modes of an air conditioner having a cooling operation function and a heating operation function, the heating and cooling mode is automatically switched based on the magnitude of the temperature of the room to be conditioned and the set temperature, and the switched mode is A stored cooling/heating mode switching unit, an automatic switching mode for operating the cooling/heating mode switching unit, a switching switch for arbitrarily selecting either the cooling mode for cooling operation, or the heating mode for heating operation, and the heating/cooling mode. An operation control unit that performs heating and cooling operation based on the output of a thermometer that detects the temperature of the room to be conditioned, and a timer that starts counting from the time when the heating and cooling is stopped due to the thermostat being turned off during cooling or heating operation, or when the heating and cooling is stopped due to an operation stop switch. death,
A timer section that outputs a signal after counting a certain period of time;
An automatic switching device for heating/cooling modes of an air conditioner, comprising a control section that erases the mode stored in the heating/cooling mode switching section based on a signal from the timer section.
