摘要： PURPOSE: To execute fresh setting by a minimum key input operation by shifting a set value to a lower limit value at a time point when the set value increased from the present one exceeds an upper limit value or by shifting the set value to the upper limit value at a time point when the set value decreased from the present one lowers below the lower limit value. CONSTITUTION: When an up key 1 is pushed, the content of display of a display unit 3 changes as shown by dotted lines and shifts to 10 deg.C, a lower limit value, when it reaches 30 deg.C, an upper limit value of a setting range. When the present set value is 27 deg.C and a set value to be set afresh this time is 13 deg.C, for instance, the present value is changed in such a way as 27→28→29→30→10→11→12→13 deg.C by pushing the up key. When the present set value is 14 deg.C and the set value to be set afresh this time is 28 deg.C, on the other hand, the present value can be changed also in such a way as 14→13→12→11→10→30→29→28 deg.C by pushing a down key 2. Accordingly, fresh setting can be executed by a minimum key input operation.
