[A] For example, if the wake-up scheduled time is set at the operation start time of the timer (1), and the time to go to work is set at the operation end time {lamp 806 is turned on}. If the switch 531 is pressed, the heating operation can be started at that time, and the heating operation can be automatically ended when the current time reaches the operation end time.

Also, it is necessary to set the scheduled wake-up time at the operation start time of the timer (1), set the time to go to work at the operation end time, and turn on the lamp 806. The override switch 5
By pressing the button 31, the heating operation can be terminated at that time.

Therefore, the timer operation can be changed by one operation, and when the current time becomes the operation end time,
It is convenient and easy to use because it returns to the usual timer operation.

(I) When the lamps 806 and 807 are turned off, the timer (1) setting switch 521 and the timer (2)
When the timers (1) and (2) are set to the effective side by pressing the setting switch 522, the operation start time and the operation end time are set to a predetermined time (this embodiment) as shown in steps S5 and S6 in FIG. In this example, the display is sequentially displayed on the display 6 for 0.5 seconds each.

Therefore, the operation start time and the operation end time can be confirmed, and if there is a setting error in the timer,
You can discover it.

[0] Timers (1) and (2) can be set for only one or both, so they can be used for morning and night, or for weekdays and holidays. It is convenient.

[E] The override switch 531 is an unlock switch. For this reason, there is no change in the mechanical position of the operation unit of the switch before and after the operation, and there is no uncomfortable feeling when the current time becomes the operation end time and the operation of the timer operation unit returns to the original.

A. In the FF type gas hot air heater A, the current time is a predetermined time (for example, three o'clock) from the operation start time.
Interval) Override switch 53 only when it is before
It is good also as a configuration to enable the override function by 1.
Yes {corresponding to claims 1, 3, 4}.

B. In the FF type gas hot air heater A, a configuration in which the override function by the override switch 531 is enabled only when the current time is a predetermined time (for example, three hours) before (operation start time -preparation time). {Corresponding to claims 2, 3, and 4}.

In this case, the FF gas hot air heater A does not enter the operating state even after the operation of the override switch 531 from the operation end time until, for example, (operation start time−3 hours). Override switch 531
There is no problem such that the vehicle is in the driving state for a long time due to the erroneous operation of.
