ABSTRACT:
A user-operable power-up mode switch included within an electronic air conditioning mode control circuit of the type including momentarily-actuated user mode selection switches and a volatile mode selection memory. In the event of power interruption, the mode selection memory "forgets" the last selected mode after a relatively short time when power supply filter capacitors have discharged. The power-up mode switch allows user selection of the particular mode in which operation resumes upon power restoration, but the user power up mode selections do not include all the operational modes selectable by the momentarily-actuated user mode selection switches. Thus operation continues in a mode at least appropriate for the season.
