Abstract
A control system with a clock or calendar based control has two time frames defined for assigning control events during different days of the week. The weekday time frame is defined as Sunday noon through Friday noon, while the weekend time frame is defined as Friday noon through Sunday noon. The defined timeframes are shifted from conventional definitions of weekday and weekend periods, which permits appropriate control scenarios to be realized that are closer to typical expectations. The control system uses a simple, two-timeframe control that permits greater flexibility in realizing lighting control applications without increased cost.
