Claims

[Scope of Claim for Utility Model Registration] (1) Display section 3 that displays the operation mode, alarm means 14, and operation on/off switch 4-2 that controls operation.
, 4-1, a combustion continuation switch that also serves as an on switch 4-2, a timer switch 4-3, set room temperature increase/decrease switches 4-4, 4-5, etc., and controls input signals from these switches. In an open-type hot air heater that controls combustion by a microcomputer 13, by continuously pressing a predetermined switch among the switches for a certain period of time, the off switch 4-1 and the combustion A control circuit for a hot-air heater, characterized in that a control microcomputer 13 is programmed with means for prohibiting inputs other than the continuation switch 4-2 and prohibiting operation inputs during stoppage. (2) In claim 1, the set-off clamp 3 indicates that a predetermined switch is pressed continuously for a certain period of time to indicate that the switch has entered the input/inhibit mode.
-4 and alarm means 14. A control circuit for a hot air heater.
