PURPOSE:To concentrate component parts on an operation panel and enable a small-sized and low cost heating and cooling unit to be provided by a method wherein some sensed signals from one variable adjuster fixed to the operation panel are classified by a selector means and applied as a timer input signal and a set temperature input signal. CONSTITUTION:When a range 'High' button 5a, for example, is selected, this signal is inputted to an output control means 11. When an input setting knob 13a is operated, an output from a variable adjusting means 13 is varied and this output signal is inputted to a timer input memory means 14 through a movable contact point 16c of a selection means 16 and a first fixed contact point 16a of normally-closed contact point. The input setting knob 13a is operated to set the desired time. The timer input signal S1 is stored in the timer input memory means 14 and then when a cooking button 5e is depressed, these signals are read by the output control means 11, a changeover means 18 is controlled on the basis of this timer input signal S1 and a signal of the range 'High' button 5a from the input means 10 in the output control means 11, and this contact point 18a is closed for a specified period of time and a range cooking by magnetron 2a is performed. |
