ABSTRACT:
The present invention is an apparatus and method for bidirectional alteration of a multivalue parameter from an initial value using a two-state manual input. In accordance with the present invention, the multivalue parameter is altered from its initial value in a first direction if the manual input is in a preselected state for less than a predetermined period of time. If the manual input is in the preselected state for a period of time longer than this first interval of time, then the multivalue parameter is altered from its initial value in the opposite direction. Additionally, if the manual input remains in the preselected state for additional periods of time, the value of the multivalue parameter is further altered in the opposite direction for each such additional interval. This invention is taught as useful in providing programs for programmable memory devices, in particular programmable thermostats.
