In the following description, for simplification of description, a case where the remote controller 25 controls a plurality of indoor / outdoor unit sets (hereinafter, referred to as units) 26 via the group control communication line GL will be described.

First, in the controller (not shown) of the remote controller 25, at time t1 (or time t3) (see FIG. 3), the operation switch of the remote controller 25 is pushed down, and the unit 26 is changed from the stop state to the operation state. It is determined whether or not the transition has been made (step S1).

In the determination of step S1, the controller (not shown) of the remote controller 25 is currently set when the operation switch of the remote controller 25 is pushed down and the unit 26 shifts from the stopped state to the operating state. It is determined whether or not the operation mode is the normal operation mode (operation mode other than various timer modes) (step S2), and if the operation mode is the normal operation mode, the process proceeds to step S6.

If it is determined in step S2 that the operation mode is not the normal operation mode, the controller (not shown) of the remote controller 25 stops the operation after the preset operation time of the currently set operation mode has elapsed ( (One-time operation) It is determined whether or not the cutoff timer mode is set (step S3). If the cutoff timer mode is set, the process proceeds to step S6.

In the determination of step S3, if the operation mode is not the cutoff timer mode, the controller (not shown) of the remote controller 25 operates every operation after the preset operation time of the operation mode currently set has elapsed. It is determined whether or not the erase-forgetting prevention timer mode is stopped every time (step S4). If not, the process proceeds to step S6.

If it is determined in step S4 that the currently set operation mode is the erase-forgetting prevention timer mode, the controller (not shown) of the remote controller 25 starts the operation in the erase-forgetting prevention timer mode (step S5). ). More specifically, the countdown (or countup) of the built-in preset counter is started.

Subsequently, the controller (not shown) of the indoor unit constituting the unit 26 performs processing at the start of operation (step S6), and shifts to normal operation processing for performing various controls during normal operation (step S7). I do.

Next, the controller (not shown) of the remote controller 25 performs the operation mode selection process and the timer mode selection process in response to the user's request (step S8).

In this timer mode selection process, it is possible to set the preset count value of the preset counter.

Subsequently, a controller (not shown) of the remote controller 25 determines whether or not the countdown (or countup) of the preset counter, which is a cut-off timer for preventing forgetting to erase, has ended, that is, whether or not the time-up time has elapsed. Yes (step S9).

In the determination of step S9, the preset counter still counts down (or counts up).
Is not completed, that is, when the time-up time has not elapsed, the controller (not shown) of the remote controller 25 shifts the processing to step S1 again, and repeats the operation of step S1 and thereafter.

In the determination of step S9, when the countdown (or countup) of the preset counter is completed, that is, when the time-up time has elapsed (time t2 and time t3 in FIG. 3), the remote controller 25 is not shown. The controller performs various stop processes for stopping the unit 26 (step S15), shifts to normal stop process for performing various controls during normal stop, and performs the process (step S12).

Subsequently, it is judged whether or not the erase-forgetting prevention timer mode has been set (step S13). If the erase-forgetting prevention timer mode has not been set, the process proceeds to step S1 again and step S1. The following operation is repeated.

If the erase forget prevention timer mode is set in the determination in step S13, the controller (not shown) of the remote controller 25 resets (initializes) the preset counter (step S1).
4), the process moves to step S1 again, and step S1
The following operation is repeated.

In the determination of step S1, the unit 2
When 6 does not shift from the stopped state to the operating state,
The controller (not shown) of the remote controller 25 determines whether or not the operation switch of the remote controller 25 has been pushed down and the unit 26 has transitioned from the operating state to the stopped state (step S10).

In the determination of step S10, when the operation switch of the remote controller 25 is pushed down and the unit 26 shifts from the operating state to the stopped state, the controller of the indoor unit constituting the unit 26 is stopped when the unit is stopped. Various stop processes to be performed are performed (step S15), and the same processes as those described above are performed.

In the determination in step S10, the controller (not shown) of the remote controller 25 is the unit 26 when the operation switch is not pushed down.
It is determined whether or not is running (step S11).

If it is determined in step S11 that the unit 26 is in operation, the process proceeds to normal operation processing for performing various controls during normal operation (step S11).
7) After that, the same processing as described above is performed.

If it is determined in step S11 that the unit 26 is stopped, the process proceeds to normal stop processing for performing various controls during normal stop (step S1).
2) After that, the same processing as described above is performed.

As described above, according to the present embodiment, when the erase-forgetting prevention timer mode is set, when the operation switch is pushed down and the unit starts the operation, the preset counter counts down (or counts up). To determine whether or not the count value of the preset counter has reached a predetermined value, that is, whether or not a predetermined time (for example, 8 hours) has elapsed since the unit started operating, The operation of the unit is automatically stopped when a predetermined time has passed since the operation was started. Furthermore, since the preset counter is automatically preset in preparation for the next operation, it is possible to reliably prevent forgetting to turn it off without having to set a timer each time the operation is performed.

In the above embodiments, only the case of controlling the remote controller 25 has been described, but it is also possible to configure other controllers such as the main controller 2 to perform similar control.

Further, in the above embodiments, the case where a plurality of indoor / outdoor unit sets are controlled has been described, but it is also possible to make the same control independently for each indoor / outdoor unit set. is there. In this case, the operation may be stopped at different elapsed times for each indoor / outdoor unit set.
