PURPOSE:To shorten the time spent by changing the set value of room temperature by detecting a jump instruction of room temperature by a single switching operation and then generating a control signal which changes it to a new value jumped by several steps. CONSTITUTION:There is provided a control circuit 3 which changes the set value to another value jumped by several steps when detecting a jump instruction. Namely, if an UP switch which is a means 7m of setting room temperature is depressed over 2sec, the set value of room temperature is set to be a maximum temperatue of 32 deg.C, for example, and if the switch is depressed for less than 2sec, the set value is set up by 1 deg.C. On the other hand, if a DOWN switch is depressed over 2sec, the set value is set to be a minimum temperature of 18 deg.C, for example, and if it is depressed for less than 2sec, the set value is set down by 1 deg.C. Each control member 5 is controlled via a group of actuators 4 to have the room temperature rise up or down according to the signals detected by a group of various sensors 6 and the other signal selectedly generated by the switches on a control panel 7. If the set value is required to be greatly changed to a newly set value, it may be obtained within a shorter expenditure of time for the changing because of the ability of jumping at a stride. |
